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 AP motors, can damage the compass
and cause it to work incorrectly. If the 350 QX2 AP 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.
