Default Sab 500 taill kicks when switching banks.

Hello folks


Heli flies fine,

No tail kicking during pitch pumps or anything

But when i go from idle up 1 to idle up2, there is a very significant tail kick.

It was not there before, it came after I rebuilt this heli

Nothing was changed, same pulleys, every thing same.

What FBL?

Is your head speed changing too quickly?

Something changed in the FBL controller.
Tail comp, tail gain, ESC gain, RPM ramp-up - etc, etc, etc.

Was anything done that could have altered the tail neutral point?
I would suggest setting up your TV to have a switch that changes the gyro mode from heading hold to rate mode. Take off like you normally would in HH mode, get into a stable hover a bit off the ground and plenty of space around the heli, and flick it into rate mode for a moment and then back to HH mode. Watch what the tail does in rate mode. The heli should not rotate, or should only rotate a very small amount very slowly. If it spins around with any amount of speed, the tail servo pushrod and/or servo neutral point needs to be adjusted.
Improper tail neutral setting can cause some funky stuff
