[QUOTE="pvolcko, post: 91167, member: 1376"] I agree, try reversing the tail correction direction in the gyro settings. It looks like the rudder stick reverse is set correctly because that was holding the tail it in place until you let up on the stick, at which point it likely started dialing in a bunch of incorrect "correction" to fight the stick input you were giving it, and it started spinning. To verify that your tail correction direction is correct. In heading hold mode if you place the heli down, power up the system, and then physically turn the heli CCW about 90 degrees, the tail blades should end up pointing in the direction the tail moved (in this case to the right). They will be oriented so as to push air out to the right, to correct for the uncommanded yaw. If you then move the heli back to where it started the blades should return to their starting position. Turn the heli CW 90 degrees and the tail blades will again turn into the turn (left), thus trying to push air to the left to return the tail to where it was. With the gain as high as you have it (still at 80-90 right?) I would expect there to be a great deal of fast tail wag around the hold position once you get the correction direction set correctly. If that's the case, dial back that gain setting until it holds well on the ground and then in a hover. I'd move away from that truck or anything else before trying to hover it. Would hate to see you blade strike and end up with something dented and a heli repair job once again. [/QUOTE]
