3GX tail hunting
600EFL with 3GX flying fine suddenly started to start tail hunting 5 minutes into a flight. Alteration of gain makes no difference. Any ideas why it would suddenly start to do this. Checked all linkages etc.

Binding or bearings in the tail mechanism or tail servo in trouble are two possibles. Not sure if you running belt or TT.

What voltage you running the servo on, does it get hot/warm?Have the new bearings mean you need to reduce gyro gain?

The heli is completely standard 600EFL Pro (Align regulator ) Tried lowering and raising gain still wags both ways.

Are you running a governor, if so try lowering its gain, could be a headspeed thing.
