Tail servo and the heading hold gyro setup
1. Install the Gyro and the tail servo.
2. Connect the tail pushrod to the servo.
Make sure the servo arm is 90 degrees
to the tail pushrod. The ball link
should be set at the second hole on
the servo arm (as shown on left).
3. Slide the servo mount and the tail
servo along the tail boom until the
tail pitch lever is parallel to the
tail output shaft or slightly
forward.
4. Set the Gyro limit properly, make
sure the tail pitch yoke do not touch
the tail pitch lever mount and the
tail rotor hub when the tail servo
moves to the left and the right
maximum travel volumn. If the Gyro
you used do not have the function
of Limit , set the function of ATV /
End Point / Travel Adjust on
transmitter to adjust the proper
travel volumn of the tail servo.
5. If the tail oscillates or wags at
less than 60% gain,you will need to
move the ball link to the hole which
is closer to the serve Gyro
limit properly. The ideal gain setting
is around 70%.
Important:
Do not touch the
tail pitch lever
mount and the
tail rotor hub.
