View Full Version : mini vbar with tail wobble!!

08-12-2010, 12:22 PM
I just gone fbl with a mini vbar v4, the tail is lovely in normal (2200 rpm) but when i go into st1 (2400) it wags like a happy dog flip back to norm and its locked in again !!!
The gains on 90 in the vabr

Try turning the gain down. When you switch modes, you will probably need different gain settings.

Also, what size is your tail servo? And how far out is the ball from center? What you need to make sure of is that you have around 45 degrees of servo arm movement each way from center to the ens of the available tail travel. For a full size servo, I believe I have 10.5mm on mine.
