Spirit tial kick question.

[the-borg]

I have recently swapped out my ar7200bx from my Trex 500 for a Spirit FBL system because I wanted a recovery system out system (long story only one good eye now)
Any way it all fly's circuits and hovers all ok, but if I punch the throttle the tail kicks to the right.
I have checked all the setting several time and I'm sure they are correct.
I have a DX18 and running 70% gyro
The unit is at the latest level 2.4

Any thoughts would be welcome.

First thing is to make sure that the gain is as high as possible without causing oscillation on the tail. Only sure way to do this is trial and error, just keep increasing the gain until you just begin to notice the onset of oscillation (usually happens in fast forward flight). Once you find the limit just back it down a few points. If the gain in the Tx is getting close to 100% you can increase the 'common gain' multiplier in the 'sensor' tab in the software.

If the tail still kicks at all then dial in some 'Revomix' (called' pre-comp' in some other FBL) which is on the advanced tab in the software, something like 15-20% is a good starting point (default on Spirit is zero)

Spirit have a tuning guide

Thanks for the reply's I will read the tuning guide and try the Gyro gain I think mine is set at 70% at the moment

'Rovomix' was what fixed it for me. Most FBL have this set at about 20% by default but the Spirit for some reason has it at zero.
