GT 5 problem!!!

[raptor5090]

Hello
I have a problem with the whole heli, is quite strange movements of the tail and the swash that when I pitch pump the heli ore do som tic toc the head tail moving from side to side so that they feel like it is not enough gain. DMA cyclic and pitch should this only be negative value, or can it be positive value to?
. My set-up are:



Here are my GT5 settings

Negative and positive, you need to check that on the bench. If you move collective up and down, tail must try to rotate heli in main rotor rotation direction.

sounds like 'wobble' ,maybe its too much P/I , i found i just had to experiment with lots of settings to find what works. Once you find cause and effect with one setting you can go back and change other values you may have shifted unnecessarily.
