GT 5 problem!!!

raptor5090 · 04-25-2012, 04:57 PM

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
Heli Specs:
Align 620
Align 650
CC 160 hv ice 2
Motor: KDE 495

P/I Gain Menu:
Swash:
P Gain: 95
I Gain: 70
I-D Stick: 100
D Sense: 25
Feed Forward: 85
I-lim: 18
Hover: 4
Tail:
P Gain: 98
I Gain: 70
D Sense: 25
Tail D-DB: 5
Tail Symmetric: 0
Tail Stick Dyn: 36
DMA Cyclic: -20
DMA Pitch: -80
Smooth Stop: 0
Swash Plate Menu:
Pitch Mix: 98
Ail Mix: 70
Ele Mix: 70
Stick Menu:
Expo Tail: 20
Expo Swash: 20
Rest is set at default
I have about 25% expo in the radio too.

I hope you understand :-) My English is not the best

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.
