Heading Lock Gain Too Low

Pirouettes are inconsistent in fast forward

flight or in crosswind conditions.

Heading Lock Gain Too High Fast tail-direction changes are more

difficult to control. The tail may also move

gently while hovering or flying around

and will bounce back when stopping the

rotation.

5. If the helicopter continues to pitch up after increasing the swashplate gain,

you may need to use faster and stronger servos or blades designed for

flybarless helicopters.

D. Tail Heading Lock Gain

Heading Lock gain determines how constant the tail will maintain the rotation rate

from the rudder stick.

1. Start with Heading Lock gain set to low or very low and maximize the tail gain

in your transmitter.

2. Increase the Heading Lock gain in the AR7200BX until the desired result are

achieved.

When the appropriate setting is determined, it is usually necessary to re-adjust the

tail gyro gain in the transmitter.
