I
NSTALLATION AND
A
DJUSTMENT
•When making GY502 adjustments, always
use the accessory miniature screwdriver
and do not apply excessive force.
Sensor installation precautions
•Always use the accessory sensor tape to install the sensor. Install the
sensor to the center of the sensor tape.
•Depending on the vibration from the helicopter, the sponge may tear
near the corners of the sensor tape. If the helicopter is flown in this
state, vibrations will not be sufficiently absorbed and the sensor may
fall off. Before flight, always check the sensor installation state. If the
sponge is torn, replace it.
Installing to Fuselage

Installing sensor and amp
•Install the sensor so that the
bottom of the gyro is perpendicu-
lar to the main rotor shaft axial
direction. Offset of this axis will
also react in the roll and pitch
directions.

Frame gyro bed
Install the GY502 sensor to the fuselage using the accessory sensor
tape. Also routinely check the sensor tape and replace the tape if it is
saturated with oil or partially peeled.
*Oil on the sensor bottom and the part installed to the frame can be
wiped off with cleaner, etc.
Installing control amp
•When installing the control amp, after the end of sensitivity adjust-
ment, vibration-proof the amp by wrapping it in sponge, the same as
the receiver.
