Trex 450 Tail twitch

[Bruno28]

Hey,

what do i need to set in order to stop tail twitch from happening when i fly left or right?

Not sure which heli your refering to, but it looks like from your sig that you probably know to try lowering gyro gain in tx and look for a vibration. Mounting tape is also a consideration.

Did it just start out of the blue? New set-up? Recent crash?

When hovering and coin forward flights it doenst do any tail twitch.

Its a trex 450 Pro V2 FBL.
I did crash it once and rebuild it, but did not change any settings besides: tail endpoints, swashplate centring, teaching the cyclic pitch geometry, adj collective pitch range, adj cyclic swash limit.

But even before the crash it did this, but i was lazy to fix it.

I had a similar issue. Changing the tail bearings solved my problem. I changed them all but I suspect the two real culprits were the outer bearings in the blade grips.

Best of luck.

Yeah i change my bearing too. Before it was a bounce. Now its just a fast twitch.
