Hey guys.

Well, as the title suggests, im having a really weird issue with my JR770T 8900G combo, and my dx7.

Well, in normal mode(Gyro below 50%), the tail servo seems to move equally in both directions.
Left travel = Right travel.

However, in HH mode(Gyro above 50%), the tail servo does not want to move equally in both directions.
I know some may speculate that this is normal gyro behaviour. But the difference in servo travel is HUGE.

Left rudder is only a small amount, while right rudder is so much that the tail binds. I've tried it in the air, and it is what it seems.

Way too much right to control, but way too little left.

ATV is equal both ways.
Subtrim at 0%
Servo centered.
Gyro limit does not solve the problem.

Anybody at all? I didn't seem to have this issue when i was using my multiplex evo9.

Thanx so much guys.

Set up in HH only put the tail slidder in the middle and make sure all the controls are all at 90 deg

Keep the gain low im using only about 20% with 11mm servo arm,also make sure your left piro is the same speed as right piro

yes well what you need to do is set the tail in the centre on the tail slideer but only set up in HH mode, i had the same problem when i set up in rate mode on the trex600.
