Attach propellers

Remove the rings from the propeller 

packages. Select the ring with the 

smaller internal diameter, and insert 

it into the back of the propeller hub.

Remove the nuts and washers from 

the motors. Add SFP propellers to the 

the front-left and back-right motors 

and SF propellers to the front-right and 

back-left motors with the writing on the 

propellers facing towards the sky.

Charge battery

Place the washer over the propeller, and 

secure the nut tightly on top. Always 

ensure that the propellers are fastened 

tightly to the motors before flying.

LiPo 3A

Connect the charger to the power 

adapter cable and a wall outlet. 

Connect the red cable to the + port 

and the black cable to the - port.

Set the charger to LiPo and 3A.

Protect battery from extreme heat, extreme cold, puncturing, 

and flammable surfaces. Always transport, charge, and store 

battery in the guard bag.

Charge battery using a designated LiPo balance charger only. 

Always monitor battery while charging.

Flying with a low battery is a safety risk and can render battery 

unusable. Always discontinue use when you receive a low 

battery notification, and always fly with a fully charged battery.

Inspect battery for damage before takeoff and after landing. 

If you observe any swelling of the package or battery ceases 

to function, locate your local battery recycling center to dispose 

of battery. In the US and Canada, visit call2recycle.org to 

find a location. Do not dispose of battery in the trash.

On 3DR transmitters, use the two-position switch and the

Stabilize mode

Stabilize allows full manual control of 

altitude, position, and orientation without 

autopilot assistance. Use stabilize for 

acrobatic flying and to recover your copter.

Loiter mode

With automatic autopilot control of

altitude, position, and orientation, loiter is the 

easiest way to fly. Just release the sticks and the 

copter will hover in place.

Altitude hold mode

Set the left stick to center, and the copter will

Adjust altitude and orientation with the left 

stick, and navigate with the right stick.

Your copter has powerful motors and high-speed propellers. Never place your hands near propellers 

while the motors are armed or the safety button displays solid red. Always press and hold the safety 

button until it displays blinking red before handling. 

Always fly in an open area away from people and buildings; do not attempt to fly indoors or in a confined 

space. Do not fly over people, near airports, or in any situation that could pose a hazard to those around 

you. Always fly within your line of sight and in compliance with local regulations. Your copter will not 

avoid obstacles on its own. As the operator, it is your job to recognize and avoid obstructions while 

flying. Always follow the preflight and postflight steps in the order described in this manual and the 

flight checklist, and remain attentive at all times while flying.

Environmental factors, such as wind and GPS irregularities, can cause instability in flight. Your copter will 

attempt to compensate for these factors by automatically landing if it detects an unsafe flying condition 

due to loss of RC signal, loss of GPS signal, or low battery. To avoid potential hazards due to 

environmental factors, identify the boundaries of your flying area before takeoff, and recover the copter 

manually by switching into stabilize mode if it moves outside your designated flying area. If you observe 

any inconsistent behavior, land, and consult the troubleshooting guide at 3dr.com/learn.

Always use an RC transmitter as a primary or backup control system when flying. Ensure that the 

transmitter is turned on any time the copter is powered. If contact with the transmitter is lost during 

flight, the copter will land and display a blinking yellow light. If the copter is more than 2 meters (6.5 

feet) from the launch point, it will return to launch (RTL) before landing.

Autopilot-positioned flight modes (loiter, autonomous, and return-to-launch) require an active GPS 

signal. If GPS signal is lost during flight, the copter will land and display a blinking blue and yellow light 

with a high-high-high-low tone. Always choose an unobstructed flying area to improve signal strength.

When the battery reaches 25% of its remaining charge, the copter will land and display a blinking yellow 

light with a quick repeating tone. If the copter reaches the low battery limit during a mission, it will return 

to the launch point before landing.

altitude of 15 meters, return to the launch

Flying

Select an open area for flying, away from people 

and buildings, and remember to bring the flight 

checklist and a fully charged battery. Follow these 

steps every time you fly.

Attach the battery to the underside of the 

copter using the velcro straps, and join the 

yellow connectors.

Determine the boundaries of your flying area 

before takeoff, and select a level, unobstructed 

space as a launch point. Place the copter at the 

launch point with the blue arms facing away 

from you, and stand back.

1 Turn on the transmitter. Set the left stick fully 

down, and select a flight mode. Check that 

the propellers are tight, the antennas are 

vertical, the GPS mast is vertical, and all the 

components are secure.

Check Pixhawk’s LED. If you plan to fly 

only in stabilize or altitude-hold modes, 

wait to see the blinking blue light. 

If you plan to use loiter, autonomous, 

return-to-launch, or other GPS-required 

modes during your flight, wait to see the 

blinking green light, indicating GPS lock, 

before arming.
