1 System Description

Solo is a reliable, easy-to-use quadcopter optimized for capturing aerial video and still imagery. This section 

provides a technical description for the 3DR Solo system, including components, communication, control, telemetry, 

and operator interaction.

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.

The 3DR Solo system includes the Solo quadcopter, 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.

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 WiFi network. Solo is optimized for aerial imagery 

using a GoPro® HERO camera.

Controller

The controller provides joystick, button, and dial 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.

App

The “3DR Solo” app outputs a live video stream from Solo’s onboard 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 connects to the 3DR Link network to receive video and telemetry 

outputs and send control inputs.

when the battery is connected.

Motors and Propellers

Solo’s arms are labelled 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. Conversely, motors on arms #3 and #4 spin clockwise and 

use clockwise-tightening propellers with black tops. 

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.

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 and charge the camera during flight.

Figure 1.2.1: Solo Exterior Overview

*Flight time varies with payload, wind conditions, elevation, temperature, humidity, flying style, 

and pilot skill. Listed flight time applies to elevations less than 2,000 ft above sea level.

1.5 Autopilot

Solo uses a Pixhawk 2 autopilot running APM:Copter 3.3-dev 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.

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 Electronic Speed Controller (ESC) that regulates the rotation of the motors to achieve the speed 

commanded by the autopilot.

Figure 1.6.2: Solo Motor Order

1.7 Electrical System

Battery

Solo’s onboard electrical system is powered by a rechargeable lithium polymer battery. The battery communicates 

over I2C with the Solo mainboard to report information about it’s current voltage. This information is pushed over 

the telemetry output to the operator to provide data for in-flight power management and battery failsafe. 

Mainboard

The Solo mainboard passes regulated voltage to the computing components onboard Solo: Pixhawk 2, 3DR 

Solo Link, 3DR Solo GPS, and 3DR Solo Compass. These components have a two-way serial signal link with the 

mainboard to transfer data between them via the mainboard as a central hub. The LEDs on each arm of Solo are 

components of the ESCs and receive power and I2C signals via the ESCs.

Controller

The controller is powered by a rechargeable lithium ion battery. The controller mainboard monitors the battery’s 

voltage and passes regulated voltage to the other components of the controller. 3DR Controller Link, the LED 

screen, and the controller’s input devices (buttons, dials, and joysticks) receive regulated voltage from the battery 

via the mainboard. The data signals between the mainboard and the components are one-way with the exception of 

3DR Controller Link, which communicates with the mainboard over a two-way serial link

1.8 Communication

To communicate with the operator, Solo runs three communication flows: joystick control input, video output, and 

control input/telemetry output. 

Controls

The operator can initiate control inputs from the controller or the app. On the controller, the mainboard receives 

inputs from the joysticks, buttons, and dials and converts them to MAVlink commands. The mainboard sends the 

MAVlink commands to 3DR Controller Link for transmission to Solo over the 3DR Link WiFi network. When initiated 

from the app, control inputs are sent from the app over the 3DR Link network and received by 3DR Controller Link 

which re-transmits the inputs to Solo over the 3DR Link network. The redirection of controls from the app is due to 

the improved range of the controller’s antennas. Solo receives the controls through 3DR Solo Link and transfers to 

the data to Pixhawk via the Solo mainboard.

Smart Shots

Solo’s Smart Shots are autonomous flight patterns that make it easy to create aerial video. Smart Shots allow the 

operator to choose points of interest in 3D space and fly specific patterns in relation to those points. The operator 

can control Smart Shots from either the controller or the app. When using the controller with Smart Shots, the 

joysticks are re-mapped to restrict Solo’s movement within the limitations of the Smart Shot. On the app, touchscreen controls provide the same functionality as the joysticks. To Smart Shot control inputs and telemetry outputs, 

the Shot Manager software module runs on 3DR Solo Link and regulates all control inputs to ensure compatibility 

with any active Smart Shots. 

Telemetry Output

Telemetry data from Solo is pushed from Pixhawk to 3DR Solo Link via the mainboard and transmitted to the 

controller over the 3DR Link network. On the controller, 3DR Controller Link receives the outputs, translates the 

MAVlink commands, and displays the live values on the controller’s screen. To transmit data to the app, 3DR 

Controller Link forwards the data to the app through the 3DR Link network.

2 Setup

This sections covers everything you need to set up Solo out of the box.

2.1 In the Box

Solo includes the quadcopter vehicle, controller, propellers (four plus two spares), Solo charger, and controller 

charger.

Figure 2.1.1: Solo Parts

2.2 Battery

Solo is powered by the rechargeable Solo Smart Battery that provides approximately 25 minutes of flight time per 

full charge. (Keep in mind that flight time depends on payload, wind conditions, elevation, temperature, humidity, 

flying style and pilot skill, so the actual flight time may vary.) As a lithium polymer battery, the Solo Smart Battery 

requires specific handling practices to ensure safe operation and prevent accidents. For more information about 

battery safety, see section 20.

Charging

The level of the battery is indicated by the lights below the power button. Press the power button once to display 

the current power level. The Solo battery ships with approximately 50% charge, so charge fully before your first 

flight for maximum flight time.

Remove the battery from Solo before charging. Only charge the battery using the designated Solo charger; using a 

different charger can damage the battery or cause a fire. Charge the battery in conditions between 32° F and 113° F 

only.

To charge the battery, connect the Solo charger to the battery and a wall outlet. While charging, the indicator lights 

pulse at the current level, and when fully charged, the lights turn off. There is an additional indicator on the battery 

charger that turns from red to green when the battery is fully charged. The battery takes approximately 1.5 hours to 

charge fully.

2.3 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.

Charging

Only charge the controller using the designated controller charger; using a different charger can damage the 

controller or cause a fire. Charge the controller in conditions between 32° F and 113° F only.

To charge the controller, connect the controller charger to the barrel jack on the side of the controller and to a 

wall outlet. To check the battery level of the controller, press the power button. A fully charged controller lasts for 

approximately 6 hours. Always check the controller’s battery level before you fly, and recharge when prompted by 

the controller. The controller takes approximately 3 hours to charge fully.

3 Safety

The following best practices will help to ensure safe, successful flights and reduce the risk of accident and serious 

injury.

3.1 Location

Don’t fly Solo indoors. Always fly 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 from any 

people, vehicles, or structures. As the operator, you are responsible for navigating Solo to avoid obstacles, including 

during automated flight. 

Don’t fly within 5 miles of an airport or anywhere pilots operate manned aircraft, 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

Before flying, determine the boundaries of the safe flying area at your flying location. Be aware of any risks at your 

location, including bodies of water, structures, trees, etc. Designate a few areas as safety zones where you can 

safely land the copter in case of an unsafe situation. Throughout your flight, be prepared to recover Solo manually if 

it goes outside the safe flying area. 

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. 

3.3 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 propeller are spinning. Always hold the fly button to stop the motors before approaching Solo.

After an auto-landing or return home, Solo will automatically detect the landing and stop the motors. Do not 

approach Solo until the propellers stop spinning. After a manual landing, hold the throttle (left joystick) to the 

bottom-left corner to stop the motors.

3.4 Home Position

Abstractly, 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. In practice, the autopilot saves the home position at the location where 

the motors are started only after achieving GPS lock. If Solo does not acquire GPS lock before starting the motors, 

no home position will be saved and the return-to-home feature will be unavailable.

Read and understand these important safety instructions before your 

first flight to help reduce the risk of accident and serious injury.

Spinning propellers can cause serious injury. Never touch moving 

propellers or place any objects in the way of the propeller arcs.

400 ft 400 ft

3.5 Altitude & Safety Fence

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 other tall structures.

Solo includes a 400-foot safety fence enabled by default. This altitude reflects current FAA regulations to avoid 

potential conflicts with manned aircraft and represents a safe line-of-sight altitude. If Solo reached the maximum 

altitude, it will stop ascending and limit throttle input to stay below 400 feet. In this case, the display shown in Figure 

3.5.1 will be displayed to the user to inform them to fly at a lower altitude.

Figure 3.5.1: Controller Maximum Altitude Warning

3.6 Emergency Procedures

If Solo exhibits instability in flight or flies outside your designated safe flying area, perform one of Solo’s emergency 

recovery procedures to land safely.

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 before hitting an obstacle or to re-orient Solo for navigation.

Regain Manual Control 

During Smart Shots and other autonomous behaviors, keep the controller easily accessible, and be prepared to 

regain manual control at any time. To regain manual control during Smart Shots, press the fly button.

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.

Land

To land Solo at its current position, press and hold the fly button. Solo will land immediately at the current position. 

If Solo does not have GPS lock, there will be no automatic position as Solo descends and drifting may occur 

depending on environmental conditions.

3.7 Power Management

The controller monitors the level of the controller battery and the Solo battery in flight. If either battery reaches low 

levels during flight, the controller announces the low battery state and provides an instruction to end your flight and 

recharge the battery. If the controller battery reaches a critical level during flight, Solo automatically returns to home. 

If the Solo flight battery reaches a critical level, Solo automatically lands to prevent a crash.

3.8 Flight Battery

Use caution when handling the Solo Smart Battery; there is a risk of fire if the battery is handled roughly enough 

to damage it. 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; operating Solo at the extremes of this range can affect its 

performance. 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 or explode. 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 fire 

and 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. In the US and Canada, visit call2recycle.org to find a 

location.

For long term storage, the battery will last longer if you store it in 64° F to 82° F, between 45-85% relative humidity 

and with 50% charge (instead of at empty). Always make sure to store the battery in a place where it won’t be 

exposed to extreme temperatures or direct sunlight. 

3.9 Controller

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. 
19

Perform periodic visual inspections of the controller battery to check for any damage. 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 or explode. 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 fire and flammable materials to prevent a hazard in case of fire or explosion. Do not dispose of the

won’t be exposed to extreme temperatures or direct sunlight. 

3.10 GPS Management

Solo requires an active GPS signal for advanced automated functions and Smart Shots. After powering on, Solo will 

wait to acquire a strong GPS lock. 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)

After acquiring GPS lock, Solo will enter into standard flight, known as fly mode, and all advanced features and 

Smart Shots will be available, including return home. If GPS lock is not acquired before takeoff, return to home will 

be unavailable for the duration of the flight and the user will have the option of taking off in non-GPS-assisted fly: 

manual mode by pressing A (Figure 3.10.1).

Figure 3.10.1: Controller Waiting-for-GPS Prompt

If GPS is lost during flight, the controller will display the screen shown in Figure 3.10.2 and switch from GPSassisted fly mode to fly: manual. If GPS is recovered during flight, the user will be informed that standard fly is now 

available.

3.11 Signal Management

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 

WiFi signals can cause interference with the communication system and decrease its range. Avoid flying in 

populated areas to avoid sources of interference.

If the communication signal with the controller is lost during flight, Solo will automatically return home if it has GPS 

lock. If the signal is recovered, the user will be prompted to re-take control and cancel the return-home command.

Figure 3.11.1: Controller Signal Lost Warnings With GPS

If there is no GPS lock and the controller signal is lost, Solo will initiate an emergency landing and display the screen 

shown in Figure 3.11.2.

4 Operating Procedures

This section covers the complete procedures for flying Solo, including preflight checks, manual control, automatic 

recall, and Smart Shots.

4.1 Preflight Checklist

Before flying, check the following operating conditions.

Location

-Current location and environmental conditions are suitable for flight. (See page 18 for safe flight guidelines.)

-Solo is placed at a clear launch point, facing away from you. (See page 18 for home position instructions.)

Components

-The propellers are correctly attached. (See page 14 for propeller installation instructions.)

-The propellers can spin smoothly and without obstruction when turned.

-No components on Solo appear loose or damaged.

Power

-The controller is powered on with at least 50% charge. (See page 13 for controller setup instructions.)

-Solo is powered on with the fully charged battery. (See page 11 for battery setup instructions.)

-The camera is attached, powered on and recording. (See page 15 for camera setup instructions.)

-Your phone or tablet is attached to the controller with the Solo app on and streaming video.

(See page 15 for app setup instructions.)

4.2 Takeoff

There are two options for taking off: manual and automatic. We recommend using automatic takeoff to begin the 

flight.

Start Motors

When you’re ready to fly, the controller will prompts you to hold the fly button to start Solo’s motors. Hold fly until 

the propellers spin. Solo is now active, ready for takeoff, and needs to be treated with appropriate caution to avoid 

safety hazards.

Automatic Takeoff

Hold fly again to initiate automatic takeoff. Solo will rise to 10 ft and hover until receiving further control inputs.

Figure 4.2.2: Controller Auto-Takeoff Prompt

Manual Takeoff

Once the propellers are spinning, raise the throttle stick above the center position to increase Solo’s altitude and 

take off.

4.3 Land

There are three options for landing Solo: manual, automatic, and return to launch. We recommend automatic landing 

and return to launch.

Automatic Land

For auto-landing (recommended), press the Fly button in flight, and Solo will land at the current position. 

Optionally, you can auto-land Solo at the home position using the controller’s return to home button. (See page 11 

for more information about return to home.) After an auto-landing or return-to-home, the propellers will stop spinning 

automatically; wait until the propellers stop spinning before approaching Solo.

Return Home

The return-to-home button ends your flight automatically by first returning Solo to the home position (launch point) 

then auto-landing. The propellers stop spinning automatically after activating return-to-home.

When commanded to return to home, Solo:

1 Achieves minimum altitude of 50 feet or maintains current altitude if above 50 ft.

2 Moves to launch point and loiters for 5 seconds.

3 Lands at the home point, and the propellers automatically stop after a few seconds.

1 Current altitude in feet

 Keep Solo below 400 feet at all times. Solo returns to home if flown higher than 400 feet from home.

2 GPS signal status

 Icon illuminates to indicate active GPS lock. GPS flight, pause, return to home, selfie and cable cam 

 modes require GPS lock. Solo automatically switches to manual flight when no GPS lock is available.

3 Percentage of Solo battery remaining

 The controller provides notifications at 20% and 10% to end your flight. At 0%, Solo automatically 

 lands at the current position.

4 Signal strength between Solo and controller

 Solo returns to home if the signal between Solo and the controller is lost during flight.

5 Controller battery level

 The controller provides a notification to end your flight when the controller battery is low. When the 

 controller battery reaches 0%, Solo automatically returns to home.

6 Current distance from the home point in feet

 Keep Solo within 2,000 feet from home at all times. Solo return to home if flown farther than 2,000 feet 

 from home.

4.6 Smart Shots

Solo’s Smart Shots automate video capturing to make it easy to replicate traditional filming techniques. Smart Shots 

can be useful for designing artistic video or for automating the flight procedure to restrict Solo to within a designated 

area.

Selfie

Solo performs an automated maneuver to capture a subject in a cinematic establishing shot.

To take a selfie:

1. Navigate Solo manually so the subject appears in the video frame with Solo 

 approximately 10 feet from the subject.

2. Ensure that there is 100 feet of unobstructed space behind and above Solo.

3. Press A to start the selfie.

4. Solo flies backward 100 ft and upward 100 ft in a smooth arc.

5. Press pause to stop the automatic maneuver and use the right stick to move 

 manually along the selfie path.

Use the Solo app to configure the distance and speed of the selfie shot or to activate selfie mode 

before takeoff.

Cable Cam

Create a smooth shot by flying Solo along an invisible cable between two preset points.

To fly a cable cam:

1. Press B to enter cable cam mode.

2. Navigate Solo manually to the first point so the video displays the desired subject,

 and press A to save the first point.

3. Navigate manually to the second point, and press A again to save the second point. 

 Add a difference of altitude or orientation between the two points for an impressive 

 cinematic effect.

4. Use the right stick to fly along the cable in either direction.

Use the Solo app to configure and interact with automatic cable cam shots.
28

5 Maintenance

Solo’s 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.

5.1 Legs

To replace one of Solo’s legs, purchase a Leg Replacement Set form store.3dr.com or an authorized retailer.

1 Remove the plastic sheet from the leg.

2 Detach the antenna.
