# 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.

Figure 1.6.10.1 : Solo Motor Order 

# 1.7 LED Meanings Solo’s four LEDs indicate its status during startup and in flight.

• Solid white (front) and red (back): Ready to fly, standard flight configuration
• Pulsing white (front) and red (back): Solo is flying under autopilot control

# 3 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 your common sense to avoid unsafe situations and always operate Solo responsibly.



# 3.1 Location 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 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 5 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. 

# 3.2 Environmental Awareness Don’t fly Solo in extreme weather conditions such as rain, high winds, snow, or fog. Extreme 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. 

# 3.3 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.



# 3.4 Flight School If you’re new to flying, review the video tutorials in the Flight School area of the app before your first flight. Flight School provides useful tips for learning to operate Solo safely and correctly.

Figure 3.4.5.1 : App Flight School 

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

### Read and understand these important safety instructions before your first flight to help reduce the risk of accident and serious injury.16 

# 3.5 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 will automatically detect the landing and stop the motors. Do not approach Solo until the propellers stop spinning, and always power off Solo before picking it up. 

# 3.6 GPS Solo requires an active GPS signal for flight. After powering on, Solo can take up to 5 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 allows you to retain control of Solo. 

# 3.7 Home Position Solo’s home position is the latitude and longitude coordinates of the launch point used by the autopilot as the end point of a return-home command. The autopilot saves the home position at the location where the motors are started only after achieving GPS lock . The location of the home position depends on GPS signal strength and is usually within 1 to 2 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 7.4. 

# 3.8 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, Solo will stop ascending and limit throttle input to stay below the altitude limit. FAA regulations mandate a maximum altitude of 400 ft. to avoid potential conflicts with manned aircraft and represents a safe line-of-sight altitude. 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 ft17 

# 3.9 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.
3.9.1 Pause The controller’s Pause button allows you to stop Solo mid-air. Solo will hover at the paused location until given another command. Use the Pause button to stop Solo from hitting an obstacle or to re-orient Solo for navigation. Press Pause during Return Home or Land to pause Solo and stop the landing. Pause is available only with GPS lock.
3.9.2 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.
3.9.3 Return Home If Solo acquired GPS lock prior to takeoff, press the controller’s Home button to return Solo to the launch point and land. Use return home after receiving a low battery notification or to end your flight easily. Solo will not avoid obstacles while returning home; always verify that the return path is clear before activating Return Home.
3.9.4 Land To land Solo at its current position, press and hold the Fly button. Lift the throttle at any time to exit the landing procedure. If Solo does not have GPS lock, there will be no automatic positioning as Solo descends, and drifting may occur depending on environmental conditions.
3.9.5 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.

# 3.10 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; dispose of the battery at local 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 to 82° F environment, between 45-85% relative humidity and with 50% charge. Always make sure to store the battery in a place where it won’t be exposed to extreme temperatures or direct sunlight. 

# 3.11 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 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. 

# 3.12 Antenna Configuration For the strongest connection to Solo, position the antennas down and away from the controller so they are approximately perpendicular with Solo in flight, and tilt each antenna out and away from one another at a 20° angle.

Figure 5.3.2.1 : App - Orbit Controls 

### To control Orbit using the controller, move the right stick left and right to fly Solo along the Orbit path. Move the right stick up to reduce the radius of the orbit and move Solo closer to the subject; move the right stick down to increase the radius and move Solo away from the subject. Move the left stick left and right to temporarily override the camera’s lock on the subject and look left and right. Move the left stick up and down to adjust Solo’s altitude. Use the paddle on the top of the controller to raise and lower the altitude of the target. Press Pause at any time to stop Solo; press Fly to exit to standard flight. Solo will orbit at a constant altitude relative to its launch point, not taking into account changes in ground level. Be aware of any elevations changes at your location that would affect Solo. Always ensure there is a clear path for Solo before starting Orbit.30 Figure 5.3.2.2 : Orbit Controls


### 5.3.3 Orbit Settings Select the Orbit Settings Menu to adjust Solo’s default cruise speed in Orbit.

# 5.4 Follow Follow creates a virtual tether between Solo and your mobile device, allowing Solo to track you as you move. 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 will carry the mobile device and be followed by Solo, and the safety pilot will hold the controller and be 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.

5.4.1 Follow Setup To start Follow, select Follow from the Shot List in the app and navigate Solo to face the subject. Tap the instructional bar to begin following.

Figure 5.4.1.1 : App - Follow Setup 

### Always ensure that there is a clear path for Solo during Follow. It will not avoid obstacles that come into the flight path as a result of following the subject. Orbit Adjust radius Altitude Camera Subject altitude31 

### 5.4.2 Follow Operation Once activated, Solo will automatically follow the mobile device wherever the subject carries it. In the app, the subject can press the left and right arrows to orbit Solo around them. On the controller, move the right stick up and down to adjust the following distance, and move the right stick left and right to orbit around the subject. Use the left stick to adjust Solo’s altitude during Follow and to override the camera tracking and temporarily pan the camera left and right. At any time during Follow, press Pause to stop Solo and the camera will continue to track the subject. Press Fly to return to standard flight.

### 6.2.3 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. Avoid flying in populated areas to avoid sources of interference. If the controller becomes unpaired from Solo during flight, the controller will display the following alert and Solo will Return Home. See Section 9.3 for pairing instructions.

Figure 6.2.3.1 : Controller - Controller Disconnected Alert 

### If the signal between Solo and the controller is lost during flight, the controller will display the controller signal lost alert and Solo will Return Home. If signal is recovered while returning home, the controller will display the signal recovered alert and provide the option to regain manual control by pressing the Fly button.

Figure 6.2.3.2 : Controller - Controller Signal Alerts


### 6.2.4 GPS Signal Alerts If GPS is lost during flight, Solo will switch into Fly:Manual. In the event of a loss of GPS, we recommend landing Solo and waiting 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 include any GPS positioning. Therefore, in Fly:Manual, Solo will not hold its position when the right stick is released, and you must maintain close control over roll, pitch, and yaw. Without GPS, Pause, Return Home, and Smart Shots are not available. During Land, Solo will not be able to maintain position due to the lack of GPS positioning and will drift according to wind and other environmental conditions. If another alert occurs while Solo is in Fly:Manual, Solo will not be able to Return Home and will instead initiate a non-positioned landing at the current location. If GPS is recovered in flight, Solo will switch from Fly:Manual to standard flight (Fly), and GPS positioning will activate. The following displays show (from left to right) the GPS lost alert, Solo in Fly:Manual, and GPS recovered alert. Always choose a location with a clear view of the sky to improve GPS signal strength. **IN-FLIGHT BANNER ALERTS**

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

# 7.1 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.

7.1.1 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, Fly:Manual includes no GPS positioning so that, when you release the right stick, Solo will not hold its position; it will drift according to wind conditions and existing momentum. When flying in Fly:Manual, make constant adjustment to the right stick to control Solo’s position and use the left stick to maintain Solo’s orientation.
7.1.2 Stabilize Stabilize mode provides full manual control without autopilot assistance. In stabilize, the autopilot regulates Solo’s roll and pitch angles so that Solo 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-tuned control of both the left and right sticks to fly Solo. Stabilize does not require GPS lock.
7.1.3 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, Solo combines roll, pitch, and yaw onto the controller’s right stick. To navigate Solo in drift, move the right stick to initiate a coordinated turn in that direction. Releasing the right stick will cause Solo to drift to a stop over a two-second period. Solo does not automatically control altitude in drift, and will require constant adjustments to the throttle stick when flying in drift.
7.1.4 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. There is no altitude or position assistance in acro, so be prepared to make constant adjustment to both sticks. Acro is a copter-frame oriented mode, meaning that, in acro, Solo will always respond to controls relative to its own orientation. Acro does not require GPS lock. Advanced flight modes are for experienced operators only. Do not attempt to fly in any advanced modes unless you are comfortable flying multicopters without positioning and altitude assistance.

Do not fly in acro unless you are an extremely experienced operator. Without the proper skills, crashes in acro are highly likely.37 

### 7.1.5 Sport Sport mode in a modified version of acro that includes altitude assistance and earth-frame orientation. With altitude assistance, the throttle stick behaves the same in sport 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. 

# 7.2 Enabling Advanced Flight Modes To unlock Solo’s advanced flight modes, use the app to select Advanced Settings from the Settings menu. Toggle the Enable Advanced Flight Modes option to gain access to Solo’s advanced modes.

Figure 7.2.5.1 : App - Advanced Settings 

# 7.3 Accessing Advanced Flight Modes Once enabled, advanced flight modes can be accessed only be assigning them to the controller’s A and B buttons using the app. In the app, select Preset A or Preset B from the Solo menu. (The app must be connected to Solo to apply button assignments.) Once assigned, use the controller to activate advanced modes during flight.

Figure 7.3.5.1 : App - A and B Presets 

# 7.4 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 will be disabled. If you choose to take off without GPS lock, Solo will not save a home position at the launch point. If Solo acquires GPS lock mid-flight, the autopilot will save 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. If Solo did not acquire GPS lock prior to takeoff, do not use Return Home.38 

# 7.5 Performance Adjustment The Solo app includes options to adjust Solo’s performance to suit your flying style. To access the performance sliders, select Performance from the Solo menu. The flight slider controls how fast Solo flies and how responsive it is to controls. The camera pan slider regulates the speed that Solo rotates. Move the slider towards the turtle for slower, more cushioned movement, or move the slider towards the rabbit for faster, more responsive movement.

Figure 7.5.5.1 : App - Performance Sliders 

# 7.6 Units To change the units in the Solo app from imperial to metric, select Units from the Settings menu.

Figure 7.6.5.1 : App - Change Units 

# 7.7 Maximum Altitude Adjustment To adjust the altitude limit, select Altitude Limit from the Solo menu. If you choose to select No limit, ensure that you always operate Solo within your visual line of sight and in compliance with local regulations.

# 9 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 more between charges. Before opening the battery bay or performing any maintenance on Solo, always ensure that Solo is powered off with the battery removed. 

# 9.1 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. See Section 3.11 for information on safely storing spare controller batteries.

Figure 9.1.5.1 : Controller Battery Installation40 

# 9.2 Calibrations Use the Solo app to perform compass and level calibrations when prompted by the controller. Remove Solo’s propellers before performing calibrations.
9.2.1 Compass Calibration To calibrate Solo’s compass, connect the app to Solo Wi-Fi and select Compass Calibration from the Solo menu. 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 9.2.1.1 : App - Compass Calibration Setup 

### The app will prompt 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 9.2.1.2 : App - Compass Calibration Procedure


### 9.2.2 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. Select Level Calibration from the Solo menu, 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 9.2.2.1 : App - Level Calibration41 

# 9.3 Pairing

# 9.4 Legs Solo uses three unique types of legs: 2 legs with an antenna module (#1 and #2), a leg without any electronic components (leg #3), and a leg with a compass module (leg #4). Replacements for all types of leg can be purchased from store.3dr.com or an authorized retailer.

Figure 9.4.2.1 : Leg Types


### 9.4.1 Leg #3 To replace a standard leg, use a #2 Phillips screwdriver to remove the two screws, detach the old leg, and attach the new leg using the provided screws.

Figure 9.4.1.1 : Standard Leg Replacement Process


### 9.4.2 Legs #1 and #2 with Antennas To replace a leg with an antenna module where the antenna is physically undamaged, you’ll need to remove the antenna from the old leg before replacing it. To detach the antenna, remove the plastic sheet from the leg (1) and detach the antenna from the Velcro by carefully pulling the cable (2). Follow the standard leg replacement procedure to detach the old leg (3). 1 Compass

### 9.4.3 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. See Section 9.5 for battery tray removal instructions. 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. Since the space between the arm and the connector is limited, it may help to use a screwdriver to press the tab.

Figure 9.4.3.1 : 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.

Figure 9.4.3.2 : Insert New Leg with Compass 

### Secure the new leg in place and replace the battery tray.45 

# 9.5 Battery Tray The battery tray holds the battery and GPS in place, and allows you to access the main electronics bay. This section covers how to remove to tray to access the interior of Solo.
9.5.1 GPS Cover The GPS cover is the flat, black end cap in front of the battery tray. To remove it, use a small, flat prying tool to loosen the four clips along the back edge of the cover.

Figure 9.5.1.1 : GPS Cover Removal


### 9.5.2 Battery Tray Removal To detach the battery tray and access Solo’s main electronics bay, use a small Philips screwdriver to remove the 7 screws securing the battery tray to Solo.

Figure 9.5.2.1 : Battery Tray Removal 

### The battery tray will still be connected to Solo via the GPS cable, so carefully lift out the tray just enough to access the board beneath.

Figure 9.5.2.2 : Battery Tray Detachment 

### GPS connector46 

# 9.6 Motors 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 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 9.6.2.1 : LED Cover Removal 

### Use a #2 Phillips screwdriver to remove the four screws securing the pod to the arm.

Figure 9.6.2.2 : 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 if force is used to remove it.47 Figure 9.6.2.3 : Motor Pod Disconnection 

### Connect the 3 cables from the arm to the new motor pod. Tuck the cables inside the arm and set the new pod into place.

Figure 9.6.2.4 : Motor Pod Connection 

### Turn over Solo and secure the new motor pod into place using the 4 provided screws. Do not reuse the screws from the old Motor Pod. Finally, snap the LED cover back into place.

# 9.7 Factory Reset Contact customer support before performing a Factory Reset. This procedure can cause irreparable damage to Solo. 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.
9.7.1 Controller To reset the controller, start with the controller powered off. Hold the power and Fly buttons simultaneously until you see the controller-updating display (Figure 2.6.4.7). The controller will restart, taking up to 5 minutes, then display the green checkmark and prompt you to press A to continue (Figure 2.6.4.9). When the reset procedures is complete, the controller will display the preflight-update display (Figure 2.6.4.1). Complete the update process described in Section 2.6.4 to prepare Solo for flight.
9.7.2 Solo As part of the reset procedure for Solo, Solo will be un-paired from the controller. Start by powering off Solo. Use a paperclip or similar tool to press and hold Solo’s pair button (Figure 8.3.2.1) while powering on Solo. Release the pair button after you see the internal LED adjescent to the Pair button start rapidly flashing orange. This signals the factory reset procedure is now underway. After a few minutes, Solo’s main LEDs will start flashing different colors in a rotating pattern as the reset nears completion. Once Solo emits an initialization tone, the factory reset is complete, and Solo is now ready to be paired with the controller; follow the instructions in Section 9.3 to pair Solo with the controller. If the rotating light pattern stops, but Solo doesn’t emit an initialization tone, power off and power on Solo and follow the pairing instructions in Section 9.3.49
