# 1.4 Operating Parameters The following operating parameters apply to Solo. Always operate Solo within these parameters. Solo’s performance and behaviors may vary significantly if flying in that conditions violate the paramet ers listed below.

Figure 1.4.1 : Solo Operating Parameters * Flight time varies with payload, wind conditions, elevat ion, temperature, humidity, flying style, and pilot skill. Listed flight time applies to elevations less than 2,000 ft above sea level. ** To adjust maximum altitude, see Section 8.7. *** Depending on environmental conditions **** This top speed corresponds to Solo when operating in Fly mode. Maximum speeds for advanced modes may vary; see Section 8.1 for more information. Estimated flight time up to 25 minutes* Default maximum altitude 150 ft. (46 m) above ground level** Range .5 mile*** (.8 km) Payload capacity 1 lb. (450 g) Cruise speed 18 mph (8 m/s) Maximum speed 33 mph (15 m/s)  Wind speed limitation 25 mph (11 m/s) Operating temperature 32° F - 113° F (0° C to 45° C)5 

# 1.5 Autopilot Solo uses a Pixhawk 2 autopilot running ArduPilot Copter software. ArduPilot is open-source flight control based on the MAVlink communication protocol. Pixhawk 2 runs an ARM Cortex-M4 STM32F427 processor with 2 MB of flash memory and 256 KB of RAM. Combined with an array of CAN, I2C, SPI, PWM, and UART interfaces, Pixhawk 2 uses a suite of onboard sensors to calculate Solo’s orientation and motion in flight. This data is input into ArduPilot’s inertial navigation and position-estimation algorithms and combined with control inputs to send commands to Solo’s propulsion system. 

# 1.6 Propulsion Solo uses four brushless 880 K v motors and four self-tightening propellers for propulsion. For control and aerodynamic efficiency, two motors spin clockwise and two motors spin counterclockwise. Navigation in the air is achieved by mixing propulsion of the four motors to actuate flight control along the roll, pitch, and yaw axes. Each of the four motors is numbered by the marking on the arm. These numbers correspond to the autopilot calculations for these commands and are used for indicating motor replacement procedures. Each motor is controlled by an ESC (Electronic Speed Controller) that regulates the rotation of the motors to achieve the speed commanded by the autopilot.

• Start and stop recording (HERO4 models) while you fly so you can pick and choose the shots you want.
• Footage stabilized to within 0.1 degree of pointing accuracy for enhanced Smart Shots.
• Fine-grain camera tilt control, including angle presets and instant speed adjustment. Note : If you purchased the Solo with 3-Axis Gimbal package, skip to section “Camera Installation” on page 19
. 

# 3.1 In the Box The Solo 3-Axis Gimbal package includes the Solo Gimbal, the sunshade, four balance weights for the GoPro® camera, and a screwdriver for installing the Gimbal.

Figure 3.1.1 : Solo Gimbal Parts To install the Solo Gimbal and start utilizing its features, follow these Solo Gimbal installation instructions: 

# 3.2 Gimbal Installation Before installing the Solo Gimbal, make sure the firmware on Solo and your GoPro as well as the Solo App on your mobile device are up to date for the best performance. Recommended versions:
• Solo: 1.2.0 or higher
• Solo App: 1.2.0 or higher
• GoPro: 3.00.00 or higher 3.2.1 Remove The Frame 1. Flip Solo over to access the bottom of the vehicle. 2. The Frame is secured to Solo by three captive screws (permanently attached to the mount to prevent losing them). Since these screws don’t come out all the way, loosen each screw until they can’t be backed out any further. 3. Detach the mount from Solo by gently lifting up on it. 4. Route the HDMI cable out through the mount to complete the separation. Balance weights (4)

Loosen the three screws securing the mount. Gently detach the plate.

Free the cable, and remove the mount.

e
3.2.2 Connect Gimbal 1. Remove the foam insert holding the gimbal in place and set it to the side (this piece is used to help protect the gimbal during travel). 2. On the bottom of the gimbal plate are two ports: one for the HDMI cable and one for the gimbal cable. Plug in the cables running from Solo to their respective ports on the gimbal, as shown following.

Connect gimbal cable. Connect HDMI cable.

Figure 3.2.2.1 : Connecting cables
3.2.3 Position Cables With both cables now connected to the Solo Gimbal, it is important to position each cable out of the way of other internal components. When configuring the HDMI and gimbal cables, the HDMI cable should rest on top of the gimbal cable. 1. Position the gimbal cable out out of the way by pushing any slack towards the front of the Solo Shell.18 Tuck the Gimbal Cable’s slack into the front of the Solo body

Figure 3.2.3.1 : Positioning the Gimbal Cable 2. Loop the HDMI cable around and inside the front of the body, pushing any extra slack towards the pocket of Arm #01 as seen below.

Tuck the HDMI Cable’s slack into the side of the Solo body

Figure 3.2.3.2 : Positioning the HDMI Cable
3.2.4 Mount the Gimbal 1. Position the gimbal plate over the opening in the Solo Shell, making sure that the three screw positions are aligned (two in the back and one in front). 2. Slide the back of the plate in first, and then pinch the two front prongs in and down to insert the plate.19 Figure 3.2.4.1 : Mounting the Gimbal 3. When the plate is inserted and resting flush with the Solo Shell, tighten each of the three captive screws. If the plate isn’t resting flush with the Solo Shell, the most likely cause is that the screws didn’t catch correctly. If the screws are misaligned, do not try to tighten them. Back out any crooked screws with the screwdriver, then realign them manually before tightening with the screwdriver.
3.2.5 Camera Installation The 3-Axis Solo Gimbal holds your GoPro® HERO 3, 3+ or 4. To install your GoPro camera, follow these directions: 1. To create space for your GoPro inside the camera housing, move the the rubber HDMI plug out and away from the camera housing.

Make sure that the Wi-Fi on your GoPro ® is turned OFF. Otherwise, it can interfere with Solo’s communication signals and cause unexpected behavior.23 3.3.2 LED Signals On the back of the Solo Gimbal is an LED that signals different status modes of the gimbal.

Figure 3.3.2.1 : LED Gimbal Signal The Gimbal LED displays several different signals:

• Breathing green: the gimbal is functioning properly and ready for use. • Blinking orange: the gimbal is booting up (commonly seen while performing an update). • Blinking blue: the gimbal has lost the communication signal. Please contact customer support. • Breathing red: the gimbal is in a temporary fault mode. Restart the gimbal, and if the issue persists, please contact customer support. • Solid red: the gimbal is in an unrecoverable fault mode. Restart the gimbal, and if the issue persists, please contact customer support.
3.3.3 Troubleshooting If the Solo Gimbal is not working properly, follow the steps below to troubleshoot the problem: 3.3.3.1 The gimbal is not centered with respect to Solo

• Sy mptoms: The gimbal angle seems cockeyed or the beauty plate (at the top of the gimbal) does not mount flush with the Solo bottom surface. • Reason: Improper cable routing can cause the gimbal to be off-center. This also hurts gimbal performance because of interference on dampers. • Resolution: Make sure the HDMI cable is coiled from left to right in the big radius following the contour of the Solo. The Gimbal Data cable can interfere, make sure the Gimbal Datacable is unwound and is not twisted. For details, go to https://3drobotics.com/kb/gimbalinstallation/. 3.3.3.2 Frozen GoPro

• Symptoms: GoPro doesn’t respond to a button press, either on the camera (physical button) or in the Solo App. • Reason: GoPro firmware is not up to date. • Resolution: Your GoPro model must be Hero 3+ or higher. If so, follow these steps: 1. Remove the GoPro from the gimbal. 2. Remove the battery from the GoPro. 3. Wait 20 seconds. 4. Replace the battery. 5. Power on the GoPro. At this point, make sure the GoPro firmware is the latest version.24 3.3.3.3 The gimbal is not turning on or responding

• Symptoms : Gimbal appears not to be receiving power. • Reason: Possible connectivity issues. • Resolution: Check the LED on the gimbal (behind the GoPro) and refer to the color guide in Section 3.3.2. If the LED is off, make sure the gimbal connector is plugged in and seated properly. If none of the preceding steps resolved your gimbal issue, please contact customer support at 3dr.com/support.25 

# 4 Safety The following best practices will help ensure safe, successful flights and help reduce the risk of accident and serious injury: • Always fly under adult supervision and with your full attention at all times. • Do not fly under the influence of drugs or alcohol or when your ability to operate Solo safely is impaired. • Use common sense to avoid unsafe situations and always operate Solo responsibly.



# 4.1 Location When choosing an appropriate place to fly Solo, keep these location factors in mind: • Don’t fly Solo indoors. • Always fly outside in clear, open areas at a safe distance from yourself, other people, power lines, animals, vehicles, trees, and buildings. • When flying in areas with potential hazards, maintain a distance of at least 100 feet (30 m) from any people, vehicles, or structures. As the operator, you are responsible for navigating Solo to avoid obstacles, including during Smart Shots. • Don’t fly within five miles of an airport or within any airspace restricted by your local, state, or national airspace authority. As the operator, you are responsible for knowing and understanding the regulations that govern small, unmanned aircraft like Solo in your jurisdiction. 

# 4.2 Environmental Awareness Don’t fly Solo in extreme weather conditions such as rain, high winds, snow, or fog. Such weather conditions can permanently damage Solo or cause instability in flight. Before flying, determine the boundaries of the safe flying area at your location. Be aware of any risks, including bodies of water, structures, trees, power lines, etc, and designate a few areas where you can land Solo in case of an unsafe situation. Throughout your flight, be prepared to recover Solo manually or use an emergency procedure if Solo flies outside the safe flying area. 

# 4.3 Visual Line of Sight Always fly Solo within your visual line of sight. Don’t let Solo get so far away from you that you cannot see its orientation or so that any physical obstructions block your view of Solo. Read and understand these important safety instructions before your first flight to help reduce the risk of accident and serious injury.

Physical obstructions can also block communication signals with the controller, causing Solo to attempt to Return Home along an obstructed path26 

# 4.4 Flight School If you’re new to flying, review the video tutorials in the Flight School area of the App before your first flight (make sure your device is connected to the Internet). Flight School provides useful tips for learning to operate Solo safely and correctly.

Figure 4.4.1 : App Flight S chool 

# 4.5 Propellers

To avoid hazardous contact with Solo’s high-speed propellers, always power off Solo before handling Solo or the propellers. When prompted to start motors before takeoff, always ensure that the propellers are clear of any obstructions and at least 20 feet away from any people, animals, or property before activating. Do not touch moving propellers or approach Solo while the propellers are spinning. After landing or returning home, Solo automatically detects the landing and stops the motors. Do not approach Solo until the propellers stop spinning, and always power off Solo before picking it up. 

# 4.6 GPS Solo requires an active GPS signal for flight. After powering on, Solo can take up to five minutes to acquire a strong GPS lock. Always choose a flying location with a clear view of the sky to improve GPS signal strength. The following requirements define a GPS lock:

• Reported horizontal position accuracy < 16 ft. (5 m) • Reported speed accuracy < 2 mph (1 m/s) • Number of satellites ≥ 6 • Difference between GPS and inertial navigation vertical velocity < 2 mph (1 m/s) If satellite coverage drops beneath a reliable threshold during flight, Solo will automatically switch to Fly:Manual mode. This mode does not provide the flight-stabilizing GPS functionality, but it still lets you control Solo. Spinning propellers can cause serious injury. Never touch moving propellers or place any objects in the way of the propeller arcs while Solo is powered. 400 ft 400 ft27 

# 4.7 Home Position Solo’s home position is the latitude and longitude coordinates of the launch point and is used by the autopilot as the end point of a return-home command. The autopilot saves the home position location to where the motors are started, assuming GPS lock has been achieved. If Solo has taken off without GPS lock and then achieves GPS lock mid-flight, the home position will be set to wherever GPS lock was acquired. The location of the home position depends on GPS signal strength and is usually within one to two meters of accuracy. Always take off from an open location with a clear path for Solo to return home safely. For home position safety in advanced mode, see Section 8.4. 

# 4.8 Altitude Limit Always fly at appropriate altitudes for your flying location and local regulations. Solo cannot avoid obstacles on its own, so always select altitudes that avoid any obstacles, such as trees, buildings, and power lines. Solo includes a safety fence enabled by default at 150 ft. (46 m). If Solo reaches the altitude limit, it stops ascending and limits throttle input to stay below the altitude limit. To adjust the altitude limit, see Section 8.7. FAA regulations mandate a maximum altitude of 400 ft. to avoid potential conflicts with manned aircraft and represents a safe line-of-sight altitude. 

# 4.9 Emergency Procedures If you experience a problem in flight, use one of the following emergency procedures to stop Solo, end your flight, or shut off the motors.
4.9.1 Pause The controller’s Pause button allows you to stop Solo in mid-air. Solo hovers at the paused location until given another command. Use the Pause button to stop Solo from hitting an obstacle or to reorient Solo for navigation. During Return Home or Land, you can pause Solo and stop the landing by pressing Pause. Pause is available only with GPS lock. 4.9.2 Regain Manual Control Keep the controller easily accessible at all times during flight, including during Smart Shots, and be prepared to regain manual control at any time. To return to standard flight during Smart Shots, Return Home, or Land, press the Fly button. 4.9.3 Return Home If Solo acquired GPS lock prior to takeoff, you can return it to the launch point and land by pressing Return Home on the controller. If you receive a low-battery notification or want to quickly end your flight, press Return Home. Solo does not avoid obstacles while returning home; always verify that the return path is clear before activating Return Home. 4.9.4 Land To land Solo at its current position, press and hold the Fly button. To exit the landing procedure at any time, lift the throttle. If Solo does not have GPS lock, automatic positioning is not available as Solo descends, and drifting can occur depending on environmental conditions.28 4.9.5 Motor Shutoff In the event that Solo’s motors do not stop after landing or for an emergency in-flight kill switch, Solo includes an emergency motor shutoff procedure. To shut off the motors at any time, either in flight or on the ground, hold the A, B, and Pause buttons at the same time. An initial screen will appear on the controller to confirm the shutoff command; continue to hold A, B, and Pause buttons to activate motor shutoff. Use the emergency motor shutoff only as a last resort.

Figure 4.9.5.1 : Controller - Motor Shutoff 

# 4.10 Flight Battery Use caution when handling the Solo Smart Battery; lithium polymer batteries can cause a fire if handled incorrectly. Never alter, puncture, throw, bend, or impact the battery. Keep the battery away from liquids, fire, microwaves, and other hazardous or combustible materials. Don’t expose the battery to extreme temperatures. If the battery is hot to the touch, wait for it to cool before using or charging. Inspect the battery before and after each flight. It is possible for the battery to be damaged in shipping, use or charging. If you notice any abnormal features such as damage to the exterior shell, swelling, deformation of the battery, abnormal smell, leakage, or other unexpected behavior, do not use the battery! These can be signs of serious damage that can cause the battery to catch fire. To prevent a hazard in case of fire or explosion, disconnect the battery, and place the battery in a safe area outside of any buildings or vehicles and away from flammable materials. Do not dispose of the battery in the trash; bring it to a battery recycling center as soon as possible. In the US and Canada, visit call2recycle.org to find a location. For long-term storage, store the battery in an 64° F (18° C) to 82° (28° C) F environment, between 45-85% relative humidity and with 50% charge. Always store the battery in a place where it won’t be exposed to extreme temperatures or direct sunlight. 

# 4.11 Controller The controller’s rechargeable lithium ion (Li-ion) battery is housed inside the controller, accessible by the battery door on the back of the controller. The controller battery is pre-attached to the controller, and shouldn’t be disconnected unless: • You plan to store the controller for over three months without using it. In this case, disconnect the battery from the controller and leave the battery inside the controller to store it. • You need to replace or upgrade the controller battery. Upgraded controller batteries with double the capacity are available from store.3dr.com or an authorized retailer. In the case where you need to store the extra controller battery, store it in a location where it will not come into contact with metal objects or other batteries. If the battery’s connector comes into contact with a metal object, it can short circuit the battery and cause a fire. Keep the controller away from liquids, fire, microwaves, and other hazardous or combustible materials. Don’t expose the controller to extreme temperatures. If the controller is hot to the touch, wait for it to cool before using or charging. Perform periodic visual inspections of the controller battery to check for any damage, and handle the controller battery using the same safety precautions as the flight battery. **KILL SWITCH UI - EMERGENCY MOTOR SHUTOFF**

When you command Solo to land, it will land at the current location, wherever it is. Always make sure there is a clear path to a safe landing point directly below Solo before landing.

Never approach Solo while the propellers are spinning. After an auto-landing or return-to-home, always wait until the propellers stop before approaching or touching Solo.32 

# 5.4 Return Home The Return Home function brings your flight to an end by recalling Solo to its launch location and landing. You can initiate Return Home manually by pressing the Return Home button on the Controller. Alternatively, in certain circumstances, Solo initiates Return home autonomously; for details, see Section 7.2, In-Flight Errors, on page 53
. Keep in mind that Return Home requires enough battery charge to get back to the launch point. If you need to end your flight immediately, land manually or hold the Fly button. Return Home requires GPS lock prior to takeoff.

Figure 5.4.1 : Return H ome Button

5.4.1 Smart Return Home Functionality When a call to Return Home is triggered, it is critical that Solo make a swift and safe journey back to the Home Position. Among the factors involved in balancing these priorities are:
• The farther away Solo is, the greater the likelihood that it could encounter unforeseen obstacles (buildings, trees, etc.). Because of this, longer-distance scenarios benefit from climbing in altitude before traversing back home.
• The closer Solo is to the Home Position, measured laterally, the more confident we can be that there are fewer obstacles in the return path, and thus the safer it would be for Solo just to land. To help eliminate unnecessary ascents in favor of more efficient return flights, we developed the “Cone Zone.”

Figure 5.4.1.1 : The Cone Zone The Cone Zone represents the volume that is least likely to be filled with problematic obstacles. The shape of thiscone is based on a 1:3 ratio of horizontal distance to altitude. So as your altitude increases, so does the crosssectional area of the cone. Once Solo reaches the boundaries of the cone or is already within the cone, then its main priority is to traverse to directly over the Home Position and land. Always verify that there is a clear path to the home point before activating Return Home.33 5.4.2 Obstacle-Free Cone Zone The following examples walk you through the different flight scenarios and how the Cone Zone affects the Return Home behavior in each scenario.
Case #1: Above the Return Home Altitude

Figure 5.4.2.1 : Above R eturn Home When a call to Return Home is triggered and Solo is flying above the Return Home Altitude (default: 25m), Solo: 1. Climbs 10m 2. Traverses to the Home Position 3. Descends and lands
Case #2: Within the Cone

Figure 5.4.2.2 : Within the C one When Solo is inside the cone and Return Home is triggered, Solo: 1. Climbs 2.5m 2. Traverses to the Home Position 3. Descends and lands34 Case #3: Below the Return Home Altitude and Outside the Cone

Figure 5.4.2.3 : Below Return Home and Outside the Cone The radius of the Cone Zone expands at a 1:3 ratio of lateral distance to altitude. This means that the Cone radius is directly related to the Return Home altitude. As Solo’s altitude increases, so does the radius of the cone. If Solo’s lateral distance from the Home Position exceeds this ratio, it is then outside the cone. In the occurrence of a call to Return Home, Solo: 1. Either climbs to the boundary of the cone or to the Return Home Altitude, whichever happens first 2. Moves to the Home Position 3. Descends and lands 

# 5.5 In-Flight Data Use the controller’s main data display to monitor Solo’s status in flight.

# 6 Using the Solo App 6.1 App Interface Overview The Solo App provides a simplified interface for viewing Solo’s video feed and managing Smart Shots. The first screen in the App is the home screen:

Figure 6.1.1 : Solo App Home Screen The primary function here is to go to the main screen by tapping Fly Solo on the left side of the screen. Also, if you’re not connected to Solo and are using the Android version of the App, a Connect button appears in the top-left corner; you can connect to Solo by tapping the Connect button and following the directions. The iOS version of the app displays a Connection Instructions button instead. Additional controls at the bottom of the App home screen are as follows:
• Settings : Go to the section of the app where you can change setttings for Solo, the Controller, and the App. You can also update the software and firmware from here.
• Flight School : Takes you to a listing of instructional videos for getting started with Solo. To view the videos, your device must be connected to the Internet.
• Support : Provides resources for solving problems, logging support tickets, and related issues. Also, the home screen might display a notice: Software Update Available. This indicates that updated firmware is available for Solo, the Controller or both. The update typically features improved performance and new features. To get the update, simply tap the notice and follow the directions.39 6.1.1 Main Interface This is the screen you’ll use most of the time when flying Solo. It’s available by tapping Fly Solo on the home screen. The main screen provides the live video feed from the GoPro camera, telemetry statistics, access to Smart Shots and the map view, and more.

Wi-fi signal strength between Solo and Controller40 6.1.2 Map View To access the small map view, swipe left a short distance from the right edge of the app. To full-screen the map,swipe left again. To hide the small map, swipe to the right. To return from the full-screen map, tap the picture-inpicture video display at the top-left of the map. A live map view is normally available only with GPS lock and on devices with mobile data (cellular Internet). With a Wi-Fi only iOS device, you can cache map data automatically by connecting to the Internet, then opening the map in the Solo App and navigating to the area you want to map. Then, when you connect the device to Solo, the App automatically remembers the map. Note : Apple controls the map data; 3DR cannot guarantee this functionality. For best results, make sure your iOS device has a reasonable amount of free storage. If you’re using an Android Wi-Fi-only device such as a tablet, with a bit of preparation, you can cache a map section and call it up as needed even if mobile data is not available. You need not be connected to Solo to follow these steps: 1. Connect your Android device to Internet-enabled Wi-Fi. 2. Open the Solo App and tap Fly Solo. This takes you to the main screen, which informs you that Solo is not connected. 3. Position your finger at the right side of the screen and swipe all the way left. This takes you to the map screen, which should resemble the following illustration after loading map data:

Figure 6.1.2.1 : Initial Map Screen 4. To begin the caching process, tap the Download button ( ) at the right-center of the screen.

Figure 6.1.2.2 : Map Screen During Caching41 Important : If you do not see the Download button, you can enable it by going to Solo App home screen > Settings > Map Tile Provider and choosing Map Box. 5. Use standard touch-screen gestures to find the map area to cache (that is, the area you’re planning to fly in), then, to save the map, tap the “Pan and zoom ...” message at the bottom of the screen. During caching, a progress bar appears, and then the message “Map area saved!” appears shortly above the “Disconnected ...” message. 6. Proceed to the map area with your Solo, start flying, and access the map as usual. If the map is full-screen, and you have a live video feed, the video appears in the picture-in-picture (PiP) rectangle near the top-left corner of the screen. To return to the main flying screen, tap the PiP rectangle (whether or not it’s displaying video). 6.1.3 Camera Controls and Settings The Record button on right side of the main App screen lets you start and stop recording with the GoPro camera (3-Axis Gimbal only). When Video Mode is active the button is red, and when Photo Mode is active it’s white. When recording video, the red circle changes to a smaller square and the small “LED” icon above the button pulses red. To stop recording, tap the square button. The area just above the button contains status icons. From left to right, these are Camera Roll (recording video to the mobile device), GoPro (recording video to the camera), and video-recording status. Below the button is a sliders icon that provides access to camera settings. The following illustration shows different states of the record button and associated icons:

Figure 6.1.3.1 : Camera button states
• A: Video mode, not recording
• B: Video mode, recording (note camera settings disabled)
• C: Photo mode
• D: Video mode, GoPro recording disabled (camera might be off or missing memory card)
• E: Video mode, Camera Roll recording disabled by Camera Settings control42 To access the camera settings, tap the sliders icon immediately below the record button:

Figure 6.1.3.2 : Tap for Camera Se ttings Tip : You can change camera settings while flying as long as you’re not recording. The two camera-settings areas, available from the buttons on the right side of the screen, are Camera Mode and Camera Settings:

Figure 6.1.3.3 : In-App C amera Settings

• Camera Mode : Determines what happens when you tap the Record button on the main App screen.

Choose Video Mode for recording continuous video; choose Photo Mode for shooting stills.

• Camera Settings : Provides access to the following parameters. The available values for each parameter

vary depending on the GoPro model and other current parameter values. For details, consult your GoPro manual. For recommended values, see the table in Section 3.2.9, Recommended GoPro Settings, on page 22
.43 Note : All of these settings apply to Video Mode only, except for Photo Resolution, which applies to Photo Mode only.

• Video Resolution (in pixels): The resolution the camera uses to capture video. To set still-image

resolution, use the Photo Resolution setting instead.

• FPS : Frames per second.

• FOV : Field of View

• Low Light : On or off

• Protune : On or off

• Photo Resolution : The resolution the camera uses to capture still images in Photo mode.

• GoPro Model : Choose the model of GoPro camera you’re using. This setting determines the available

parameter values.

• Save to Camera Roll : When on and recording video to the camera, the mobile device also records the

video received by the app from Solo to its internal memory. The Camera Roll video is available via the same methods as video recorded directly with the mobile device. For instance, if using an iOS device, you can access the Camera Roll video from the Photos app.

• Record during shots : GoPro automatically records video whenever a Smart Shot is active. To exit the camera settings, tap “Done” or anywhere to the left of the settings area.44 

# 6.2 Smart Shots Solo’s Smart Shots automate video capturing to make it easy to get stunning aerial video. By default, Cable Cam and Orbit are assigned to the controller’s A and B buttons. Use the app to access Selfie or Follow. Smart Shots are available only with the Solo app. Tip : When using Smart Shots without a Solo Gimbal, Solo cannot ensure that the subject is in the frame at all times. If this is the case, you can improve the chances of keeping the subject in the frame by adjusting the camera mount so the camera is fixed at an appropriate angle. To access the shot list, tap the Shot List button ( ) on the main App screen:

Figure 6.1 : App - Main Screen Then, on the next screen, tap the icon for the Smart Shot you want to use:

Figure 6.2 : App - Shot List Tip : To see directions for a Smart Shot, tap its icon while Solo is on the ground.45 

# 6.3 Selfie In Selfie, Solo flies a smooth up-and-back path to capture a subject in a cinematic establishing shot. Before starting a Selfie shot, always ensure that there is a clear path 200 feet (61 m) behind and above Solo. Once you activate Selfie mode, Solo flies up and away from the subject to a point 164 feet (50 m) from the subject at 82 feet (25 m) altitude. You can change these default distances with Selfie Options.

Figure 6.3.1 : Selfie Path and Settings 1 Distance away (default 164 ft.) 2 Altitude up (default 82 ft.) 3 Flight path

6.3.1 Selfie Setup To start Selfie, fly Solo to a starting point, facing the subject from approximately 10 feet away, and select Selfie from the Shot List. The app prompts you to position Solo so the camera is facing you and to ensure that the path it will follow (up and back) is clear.

Figure 6.3.1.1 : App - Selfie Activation
6.3.2 Selfie Operation To move Solo along the Selfie path, tap the forward and back arrows in the App, labeled “Fly out” and “Return,” respectively. The default cruise speed when using Selfie is 9 mph (4 m/s). 2 1 3

# 6.4 Cable Cam Cable Cam creates a smooth shot by flying Solo along a virtual cable between any two points that you specify initially.
6.4.1 Starting Cable Cam To start Cable Cam, press A on the controller, or select Cable Cam from the Shot List in the App. You’re then prompted to fly Solo to your first point and save it as the first Cable Cam point by pressing A. Then fly to your second point and save it by pressing B. For an impressive cinematic effect, try varying the altitude or orientation between the two points. Also, if you have the Solo 3-Axis Gimbal, try changing the view angle between the endpoints. Note : The Cable Cam endpoints must be at different locations. If you try to set a second endpoint at the same position as the first, the new endpoint overwrites point A and you’re prompted again for a second point.

Figure 6.4.1.1 : App - Cable Cam Setup 6.4.2 Cable Cam Operation To control Cable Cam through the app, tap the right arrow to move towards point A and tap the left arrow to move towards point B. Cable Cam’s default cruise speed is set to 9 mph (4 m/s).

Figure 6.4.2.1 : App - Cable Cam C ontrols To operate Cable Cam using the controller, move the right stick to the left to fly towards point A and to the right to fly towards point B. To pause at the current location, release the right stick. To look left and right, disable Automatic Point Camera (see Cable Cam Settings, following) and use the left stick. This overrides the camera temporarily. To stop Solo at any time, press Pause. To exit to standard flight, press Fly. Always ensure that there is a clear path between points A and B before starting Cable Cam.48 Figure 6.4.2.2 : Controller - Cab Camera Cable

To adjust Cruise Speed, use the slider. Automatic Point Camera prevents left-stick camera control during Cable Cam. If you set different Yaw values while setting up the shot, change the direction Solo rotates between the A and B points by toggling Reverse Yaw Along Cable.

Figure 6.4.3.1 : App - Cable Cam Settings 

# 6.5 Orbit Use Orbit to fly Solo along a preset circle while fixing the camera on a central target. Note : Orbit uses the Solo App’s mapping feature. For best results, use Orbit with a mobile device that has a live mobile data link. Alternatively, if using an Android device, you can use a cached map. For details, see Section 6.1.2, Map View, on page 39
. 6.5.1 Starting Orbit Select Orbit from the Shot List. The App switches to the map screen and shows the location Solo as well as the direction it’s facing on the map. This screen also shows the orbit center point as a small bullseye, as well as a line connecting the two points. To change the location of the center point, drag the map image in the App until the desired center point is at its center. When the setup is satisfactory, press A on the controller to save the current center point. Once you set the center point, the App displays a Orbit Center Point Saved confirmation. To adjust the position of the center point during Orbit, drag the map.

Figure 6.5.1.1 : App - Orbit Setup49 6.5.2 Orbit Operation To fly Solo along the Orbit path, tap the left and right arrows. The default cruise speed for Orbit is 2.2 mph (1 m/s).

Figure 6.5.2.1 : App - O rbit Controls To control Orbit using the controller, move the right stick left and right to fly Solo along the Orbit path. You can move Solo toward and away from the subject by pushing the right stick up and down, respectively. To temporarily override the camera’s lock on the subject and look left and right, move the left stick.To adjust Solo’s altitude, move the left stick up and down. If you have the Solo Gimbal installed, you can change the pitch of the camera with the paddle on top of the controller. To stop Solo at any time, press Pause. To exit standard flight, press Fly.

Figure 6.5.2.2 : Orbit Controls 6.5.3 Orbit Settings To access the settings from the in-flight Orbit interface, select Options with the three dots at the bottom-left of the main screen. To adjust Cruise Speed, use the slider.

Figure 6.5.3.1 : App - Orbit Settings Solo orbits at a constant altitude relative to its launch point, and does not account for changes in ground level. Be aware of any elevation changes at your location that would affect Solo. Before starting Orbit, always ensure there is a clear path for Solo.50 

# 6.6 Follow Follow creates a virtual tether between Solo and your GPS-enabled mobile device, allowing Solo to track you as you move. Follow has two modes:

• Look At Me : Solo remains in one place while turning to face the subject. • Follow : Solo moves at the same rate as the subject while continually aiming the camera at the subject. In this mode you have the additional option of orbiting manually around the subject. Note : To use Follow, your mobile device must have GPS capability. Most smart phones have GPS built in, but some tablets, such as the iPad, do not. If the Follow subject is engaged in an activity that prevents them from using the controller, you are required to use a safety pilot during Follow. The subject carries the mobile device and is followed by Solo, and the safety pilot holds the controller and is ready to regain manual control at any time. Don’t allow more than 500 feet of distance between the controller and the mobile device; however, specific range limits depend on the device being used. If too much distance is allowed between the controller and the mobile device, the device could lose connection with the controller.

6.6.1 Follow Se Always ensure that there is a clear path for Solo during Follow. It does not avoid obstacles that come into the flight path as a result of following the subject.
tup To start Follow, select Follow from the Shot List in the app and navigate Solo to face the subject. When Follow starts, it’s in Look At Me mode, in which Solo remains stationary while turning to face the subject as they move. To activate Follow mode, in which Solo moves along with the subject, tap Follow at the bottom of the screen. You can switch between the two modes at any time while using Follow. The App indicates the active mode with green text and icon.

Figure 6.6.1.1 : Follow in Lo ok At Me mode51 Figure 6.6.1.2 : Follow in Follo w mode 6.6.2 Follow Mode Operation When Follow mode is active, Solo automatically follows the mobile device wherever the subject carries it. In the App, the subject can orbit Solo around them by pressing the Orbit Left and Orbit Right arrows. On the controller, adjust the follow distance by moving the right stick vertically, and orbit the subject by moving the right stick horizontally. To adjust Solo’s altitude during Follow, move the left stick vertically. And to override the camera tracking and temporarily pan the camera, move the left stick horizontally. To stop Solo during Follow, press Pause on the controller; the camera continues to track the subject. To exit to standard flight, press Fly.

# 7 Alerts The following alerts will appear on the controller in the event of a preflight or in flight error. Always monitor the controller for alerts and perform the recommended actions. 

# 7.1 Preflight Errors Before starting the motors, Solo runs a series of automatic checks to ensure that the system is ready for flight. If Solo encounters an error during these preflight checks, the controller will display the encountered error along with instructions for the corresponding calibration to perform.
7.1.1 Calibration The following errors indicate that a preflight check is in progress: altitude calibrating, calibrating solo, and calibrating compass. Please wait for the error to clear before continuing.

7.2.3 Controller Signal Alerts Flying behind solid objects, like buildings and trees, blocks communication signals between Solo and the controller. Always maintain visual contact with Solo to ensure that the signal is unobstructed. Cell phone towers and nearby Wi-Fi signals can cause interference with the communication system and decrease its range. To prevent signal interference, avoid flying in populated areas. If the controller becomes unpaired from Solo during flight, the controller displays the following alert and Solo initates Return Home. See Section 10.3 for pairing instructions.

Figure 7.2.3.1 : Controller - Controller Disconnected Alert If the signal between Solo and the controller is lost during flight, the controller displays the “Controller signal lost” alert and Solo initiates Return Home. If signal is recovered while returning home, the controller displays the “Signal recovered” alert and provides the option to regain manual control by pressing the Fly button.

Figure 7.2.3.2 : Controller - Controller Signal Alerts
7.2.4 GPS Signal Alerts If Solo loses GPS during flight, it switches into Fly:Manual. If this happens, we recommend that you land Solo and wait to acquire GPS lock before taking off again. In Fly:Manual, Solo uses the same joystick controls as in standard flight (displayed as “Fly”), but it does not use GPS positioning. Thus, Solo does not hold its position when you rlease the right stick, so you must maintain close control over roll, pitch, and yaw. Without GPS, Pause, Return Home, and Smart Shots are not available. During Land, Solo cannot maintain position due to the lack of GPS positioning, and drifts according to wind and other environmental conditions. If another alert occurs while Solo is in Fly:Manual, Solo cannot return home and instead initiates a non-positioned landing at the current location. **IN-FLIGHT BANNER ALERTS**

# 8 Advanced Settings This section provides instructions for accessing and using Solo’s advanced features and settings. 

# 8.1 Advanced Flight Modes Are you a quadcopter pro? We designed Solo to be simple and reliable, but also really fun to fly. Solo includes five advanced flight modes: Fly:Manual, Stabilize, Acro, Sport, and Drift. To access these modes, see sections 8.2 and 8.3, following.

8.1.1 Fly:Manual Fly:Manual mode is a version of standard flight without GPS lock. In Fly:Manual, the throttle stick controls altitude the same way as standard flight (Fly mode). However, because it does not use GPS positioning, when you release the right stick, Solo does not hold its position but instead drifts according to wind conditions and existing momentum. To control Solo’s position when flying in Fly:Manual mode, adjust the right stick continually and use the left stick to maintain Solo’s orientation. 8.1.2 Stabilize Stabilize mode provides full manual control without autopilot assistance. In Stabilize, the autopilot regulates Solo’s roll and pitch angles so that it automatically returns to level when you release the right stick. The throttle stick controls power and acceleration directly; it does not correspond to altitude. Stabilize requires fine control of both the left and right sticks to fly Solo. Stabilize does not require GPS lock. 8.1.3 Drift Drift modes requires GPS lock and provides a plane-like flying experience. Drift is ideal for navigating Solo using the video feed. This is known as first-person view (FPV) and provides an immersive flying experience. In Drift, you control roll, pitch, and yaw with the controller’s right stick. To navigate Solo in Drift mode, move the right stick to initiate a coordinated turn in that direction. Releasing the right stick causes Solo to drift to a stop over a two-second period. Solo does not automatically control altitude in Drift, and thus requires continual adjustments to the throttle stick in this mode. 8.1.4 Acro Acro is the most advanced of Solo’s flight modes. It provides unrestricted control over Solo’s roll and pitch angles. Acro is intended for performing aerial acrobatics, flips, and maneuvers requiring extreme angles. Acro provides noaltitude or position assistance, so be prepared to make constant adjustment to both sticks. Acro is a copter-frameoriented mode, meaning that, in Acro, Solo always responds to controls relative to its own orientation. Acro does not require GPS lock.

8.1.5 Sport Sport mode is a modified version of Acro that includes altitude assistance and earth-frame orientation. With altitude assistance, the throttle stick behaves the same in Sport mode as it does in standard flight (Fly mode). Earth-frame orientation differs from copter-frame orientation in that the direction of yaw rotation is in relation to the earth instead of in relation to the copter itself. For example, if Solo is pitched forward in sport mode and left yaw is applied, Solo will maintain the same pitch angle and rotate around the vertical axis. As opposed to in acro’s copter-frame orientation, in which, in the same situation, Solo will perform a cartwheel. Sport does not require GPS lock. Advanced flight modes are for experienced operators only. Do not attempt to use these modes unless you are comfortable flying multicopters without positioning and altitude assistance.

Do not fly in Acro mode unless you are an extremely experienced operator. Without the proper skills, crashes in Acro are highly likely.57 

# 8.2 Enabling Advanced Flight Modes To unlock Solo’s advanced flight modes using the App, choose Settings from the home screen, then select Advanced Settings. Toggle the Enable Advanced Flight Modes option to gain access to Solo’s advanced modes.

Figure 8.2.1 : App - Advanced Settings 

# 8.3 Accessing Advanced Flight Modes After you enable advanced flight modes, you can access them only by assigning them to the controller’s A and B buttons using the App. In the app, go to Settings > Solo and select Preset A or Preset B settings list. (The app must be connected to Solo to apply button assignments.) Once assigned, use the controller to activate advanced modes during flight.

Figure 8.3.1 : App - A and B Presets 

# 8.4 Home Position Safety Fly:Manual, Stabilize, Acro, and Sport modes do not require GPS lock. To take off without GPS lock, Solo must be set to one of these modes. Without an active GPS signal, Return Home, Pause, and Smart Shots are disabled. If you take off without GPS lock, Solo does not save a home position at the launch point. If Solo acquires GPS lock mid-flight, the autopilot saves a home position at that location. To prevent a potentially unsafe situation, do not use Return Home if Solo did not acquire GPS prior to takeoff.



# 8.5 Performance Adjustment The Solo app includes options to adjust Solo’s performance to suit your flying style. To access the performance sliders, go to Settings, choose Solo, and then select Performance. The Flight slider controls how fast Solo flies and its responsiveness to controls. The Camera Pan slider regulates the speed that Solo rotates. Move the slider If Solo did not acquire GPS lock prior to takeoff, do not use Return Home.58 towards the turtle for slower, more cushioned movement, or move the slider towards the rabbit for faster, more responsive movement.

Figure 8.5.1 : App - Per formance Sliders Tip : When using the Solo Gimbal, for best results set Performance to Medium. 

# 8.6 Units To change the units in the Solo App between imperial and Metric, go to Settings and then choose Units.

Figure 8.6.1 : App - Change Units 

# 8.7 Maximum Altitude Adjustment To adjust the altitude limit, go to Settings, choose Solo, and then select Altitude Limits. Scroll the list horizontally to change the upper limit. A No Limit option is available if you turn on Advanced Settings > Enable Advanced Flight Modes. If you opt for No Limit, ensure that you always operate Solo within your visual line of sight and in compliance with local regulations.

Figure 8.7.1 : App - Altitude Limit 

# 8.8 Map Tile Provider (Android only) If your device supports mobile data (typically a cell phone), you can view a map of your surroundings by swiping left on the main screen in the Solo App. This setting lets you choose whether the map data comes from Google or Map59 Box. If you’re using mobile data, the choice is up to you, but if you’re using a Wi-Fi-only device, we recommend that you use Map Box in order to be able to cache map data.

# 10 Maintenance This section covers basic operational maintenance procedures for Solo. For repairs not covered in this manual, contact 3DR Support or an authorized Solo Service Center. Solo’s exterior components are designed to absorb impact from hard landings and protect the core electronics. If damage is sustained to Solo’s legs or motors, replace them with official 3DR parts from store.3dr.com or an authorized retailer. 3DR offers an extended controller battery upgrade with double the capacity so you can fly longer between charges. Before opening the battery bay or performing any maintenance on Solo, always ensure that Solo is powered off with the battery removed. 

# 10.1 Controller Battery Replacement To replace the controller battery, open the battery door on the back of the controller. Remove the foam block and disconnect the battery from the port in the side of the battery compartment. To install a battery, connect the battery to the controller, and, for standard-size controller batteries, use the foam block to pad the empty space in the compartment. For information on safely storing spare controller batteries, see Section 4.10.

Figure 10.1.1 : Controller Battery Installation 

# 10.2 Calibrations Use the Solo app to perform compass and level calibrations when prompted by the controller. Remove Solo’s propellers before performing calibrations.
10.2.1 Compass Calibration To calibrate Solo’s compass, connect the app to Solo Wi-Fi, go to Settings > Solo and select Compass Calibration. Ensure that Solo and the controller are powered on with the propellers removed. Solo requires an interference-free environment for compass calibration, so ensure that you are away from metal buildings, reinforced concrete, or other metal structures before starting calibration.

Figure 10.2.1.1 : App - Compass C alibration Setup61 The app prompts you to rotate Solo end-over-end multiple times until the bar at the top of the screen is completely green. If the calibration fails, move to a different location and try again.

Figure 10.2.1.2 : App - Compass Calibration Procedure
10.2.2 Level Calibration A level calibration zeroes Solo’s accelerometers to recognize static states. To perform a level calibration, remove the propellers from Solo and connect the app to Solo Wi-Fi. Go to Settings Solo and choose Level Calibration from the list, and follow the prompts to place Solo perfectly still on each side in turn. In each step, wait a few seconds after moving Solo to press Next.

Figure 10.2.2.1 : App - Level C alibration 

# 10.3 Pairing the Controller

1. Turn off the Solo and the controller that you want to pair, along with any other Solos and controllers nearby. 2. Power on the Solo and controller that you want to pair. 3. Wait 30 seconds for Solo and the controller to fully boot up. 4. Identify the Pair button underneath Solo. It’s a small button inside the hole labeled Pair. You’ll need to use a paper clip, a small screwdriver, or another similar tool to push it.

Figure 10.3.1 : Pa ir Button 5. Press the Pair button underneath Solo and hold for one second.62 6. When the controller detects Solo, it prompts you to accept the pairing request as seen in the screen below. (If the controller does not detect Solo after thirty seconds, try pressing the Pair button underneath Solo again and repeat as needed.)

a to a New Leg 10.4.3 Leg #4 with Compass Solo’s right-rear leg (#4) contains the compass module. Start by detaching the leg from the arm as you would a standard leg, but the leg will not be removable until you disconnect the compass from Solo. To access the compass connector, you’ll need to remove the battery tray from Solo. For battery tray removal instructions, see Section 10.5. With the battery tray removed, locate the compass connector in the corner of the board closest to the leg being replaced. Disconnect the compass connector from the board by holding down the tab on the far side of the connector and lifting up the connector. Because the space between the arm and the connector is limited, it might help to use a screwdriver to press the tab.65 Figure 10.4.3.1 : Compass Connector on Mainboard With the compass disconnected, remove the old leg and cable from Solo. Place the new leg into position and thread the new compass cable through the arm where it can connect to the board. Connect the compass connector in the same place as the old compass.

# 10.6 Motor Mods Replacement motors are available as clockwise and counterclockwise Motor Pods. Use a counterclockwise Motor Pod to replace motors #1 and #2, and use a clockwise Motor Pod to replace motors #3 and #4. Replace motor pods after every 150 hours of flight or when they can no longer turn smoothly. To replace a Motor Pod, first use a small, flat prying tool to remove the LED cover form the underside of the arm.

Figure 10.6.1 : LED Cover Removal Use a #2 Phillips screwdriver to remove the four screws securing the pod to the arm.

Figure 10.6.2 : Motor Pod Removal Disconnect the wide beige connector, the red wire and the black wire to remove the old motor pod. To remove the wide beige connector (DF13), carefully lift the edges of the connector away from the pod until they pop out, then remove the connector. Don’t pull on the wires! The connector can break easily you use force to remove it.68 Figure 10.6.3 : Motor Pod Disconnection Connect the three cables from the arm to the new motor pod. Tuck the cables inside the arm and set the new pod into place.

Figure 10.6.4 : Motor Pod Connection Turn over Solo and secure the new motor pod into place using the four provided screws. Do not reuse the screws from the old Motor Pod. Finally, snap the LED coverback into place.

# 10.7 Factory Reset Performing a factory reset restores Solo and the controller to their state prior to the first flight update. Use a factory reset if you forget your Solo Wi-Fi password or need to restore Solo’s factory settings.

Step 1: Reset the Vehicle As part of the reset procedure, Solo is un-paired from the Controller. Start by powering off Solo. Use a paper clip or similar tool to press and hold Solo’s Pair button while powering on Solo. (Make sure you feel the Pair button click down underneath the paper clip to verify you have properly activated the Pair button.) Continue holding the Pai r button for at least 15 seconds
.

Figure 10.7.1 : Pa ir Button Below the Accessory Port and adjacent to the Pair button is a small orange LED Pair indicator light. Once this light starts flashing rapidly (strobing about five times per second), release the Pair button.

Figure 10.7.2 : Strobing Pair in g Light Step 2: Reset the ControllerStart with the Controller powered off. Hold the Power and Fly buttons simultaneously until you see the controllerupdating display. The Controller then restarts, taking up to five minutes, and then the screen turns off for one minute.

Figure 10.7.3 : Controlle r Reset Contact customer support before performing a Factory Reset. This procedure can cause irreparable damage to Solo.70 When the Controller reset is complete, you will see one of these two completion screens:

Figure 10.7.4 : Control ler Update As the vehicle reset nears completion, the lights under the arms change between many different colors, followed by a sequence of beeps. When the lights stop changing color, the reset is complete. Upon completion, the lights freeze on their current colors, so they might all be the same or different colors. Step 3: Reboot Solo and the Controller While rebooting, Solo emits its regular startup tones. The lights underneath Solo’s arms also light up green and change to white in the front and red in the back. If you do not hear and see these s ignals, then reboot Solo again. If t he lights change colors now, then the vehicle is still resetting. Let Sol o finish resetting and then reboot Solo again once the lights stop changing colors. After you reboot the controller, it displays the Preflight Update or Waiting for Solo screen.
