# 1 Introduction Solo is a lightweight, easy-to-use quadcopter optimized for capturing aerial video. This section provides an overview of the 3DR Solo system. 

# 1.1 System Overview The 3DR Solo system includes the Solo quadcopter, Solo controller, “3DR Solo” app, and the human operator. The operator interacts with the controller and app on the ground, and the controller communicates with the Solo quadcopter during flight. 1.1.1 Solo Quadcopter Solo is a small unmanned aerial vehicle powered by four brushless motors and four propellers. Solo’s onboard computers control navigation, attitude, and communications in flight while sending real-time telemetry and video output and receiving control inputs over the 3DR Link secure Wi-Fi network. Solo is optimized for capturing aerial video using a GoPro® HERO camera. 1.1.2 Controller The controller provides controls and displays in-flight data on a full-color screen. Using twin long-range dipole antennae, the controller acts as the central hub for all communication on the 3DR Link network, receiving all communications from Solo and the app, forwarding telemetry outputs to the app, and controlling the transmission of all control inputs to Solo. 1.1.3 App The “3DR Solo” app outputs a live video stream from an onboard GoPro® camera to an Android or iOS device. The operator can use the app to view the live video with overlaid telemetry and access a simplified graphic interface for controlling Solo’s advanced functions. The app also connects to the 3DR Link network to receive video and telemetry outputs and send control inputs.

# 1.2 Aircraft Overview 1.2.1 Smart Battery The battery connects to Solo’s battery bay. Solo’s power button is located on the battery; Solo can only be powered when the battery is connected. 1.2.2 Motors and Propellers Solo’s arms are labeled one through four on the ends of the arms. Motors on arms #1 and #2 spin counterclockwise and use clockwise-tightening propellers with silver tops. Motors on arms #3 and #4 spin clockwise and use counterclockwise-tightening propellers with black tops. 1.2.3 Orientation LEDs Each arm contains an LED for ground-to-air directional awareness; the two front arms (#1 and #3) display white, and the two rear arms (#2 and #4) annunciate red. This LED scheme mimics the headlight and taillight style of a car for easy association by any operator. 1.2.4 Fixed Camera Mount and HDMI Cable Solo includes a GoPro® The Frame fixed mount to mount a GoPro® HERO camera. The HDMI cable connects to the GoPro® to output video during flight.

# 1.5 Autopilot Solo uses a Pixhawk 2 autopilot running APM:Copter software. APM:Copter is open-source flight control based on the MAVlink communication protocol and part of the ArduPilot project. 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 APM:Copter’s inertial navigation and position estimation algorithms and combined with control inputs to send commands to Solo’s propulsion system. Figure 1.5.10.1: Solo Onboard Sensors Table



# 1.6 Propulsion Solo uses four brushless 880 K v motors and four self-tighteing 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.

# 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 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. Environmental factors and GPS irregularities can cause instability in flight, and this can affect Solo’s performance or cause an in-flight failure. 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 Read and understand these important safety instructions before your first flight to help reduce the risk of accident and serious injury.17 

# 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 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 power off Solo before picking it up. 

# 3.6 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 . 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 4.4 

# 3.7 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 328 ft. (100 m). This altitude reflects current FAA regulations to avoid potential conflicts with manned aircraft and represents a safe line-of-sight altitude. If Solo reaches the altitude limit, Solo will stop ascending and limit throttle input to stay below the altitude limit. The controller will display the following alert in the event that Solo reaches the maximum altitude.

Figure 3.7.5.1: Controller Maximum Altitude Warning To adjust the altitude limit, connect to the app (Section 2.6) and select Altitude Limit from the Solo Settings 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.

Figure 3.7.5.2: App - Altitude Limit 

### Maximum altitude

# 3.9 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. The battery functions optimally when used in -4° F to 140° F. 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. In this case, do not use the battery again. Disconnect the battery, place the battery in a safe area outside of any buildings or vehicles and away from flammable materials to prevent a hazard in case of fire or explosion. 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. 

# 3.10 Controller The rechargeable lithium ion (Li-ion) controller battery is housed inside the controller, accessible by the battery door at 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 switch the controller battery for a new or upgraded controller battery. Upgraded controller batteries with double the capacity are available from store.3dr.com. 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. The controller functions optimally when used in -4° F to 140° F. 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 Solo Smart Battery.20

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 loses power or becomes unpaired from Solo during flight, the controller will display the following alert and Solo will Return to Home. See Section 7.3 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 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 the operator 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. We recommend landing Solo in the event of a loss of GPS and waiting to acquire GPS lock before taking off again. When GPS is recovered, 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.
