Airframe Maintenance

Replacing the body

Disassembly of the old airframe

1. Ensure the battery is disconnected from the

quadcopter.

2. Remove the 2 machine screws from each propeller

and remove the propellers.

3. Remove the 32 1.5mm hex screws from the bottom

of the frame to separate the upper and lower body

pieces.

4. Unplug the compass sensor from the ﬂ ight control

board. Remove the landing gear with compass sen-

sor and place it in a safe area away from magnets.

NOTICE: Do not allow the compass sensor to

get near a magnet. Any magnet, including those in

the 350 QX2 motors, can damage the compass and

cause it to work incorrectly. If the 350 QX2 is ﬂ own

with a faulty compass, all GPS functions will be

compromised.

5. Unplug the GPS receiver from the ﬂ ight control

board and remove the battery tray assembly.

6. If you are replacing the GPS components, remove

the foil from the GPS receiver and unplug the GPS

antenna from the GPS receiver.

7. Remove the ﬂ ight control board from the airframe.

8. Remove the receiver.

9. Remove the motors and ESCs from the airframe.

Before installing the components into the new airframe,

inspect all the components for any obvious damage or

burnt smells. Check the motors for smooth bearings

and inspect all the propellers for chips, burrs or cracks.

Replace any parts in question.

Installing components in the new airframe

1. Install the motors and ESCs, making sure to match

the wire colors on the connectors.

2. Install the receiver.

3. Install the ﬂ ight control board.

4. Install the tray assembly.

5. Install the GPS receiver and GPS antenna and plug

the cables into their corresponding sockets.

6. Assign the motors and ESCs according to the

ESC and Motor Assignment Procedure.

7. Install the landing gear and connect the compass

to the ﬂ ight control board. If you replaced the

compass or believe that it may have been impaired

by a magnetic ﬁ eld, you will need to perform the

compass calibration procedure.

8. Mount the top of the airframe.

9. Install the propellers, paying attention to the

direction of rotation as indicated by the arrows

molded in the frame and on the propellers for each

motor.
