One day I finally get my Raptor G2 to finally hover at least 2 ft off the ground and the next day, it starts wagging its tail side to side without me even moving the rudder control and my left trim is maxed out. What could possibly be causing this to happen? Here is my practice scenario: I fly on a calm day, let's not forget newbie here, have set my gyro sensitivity to 0% to make sure that I'm not getting help and that its me doing the work, blades are tracked (all 4) and finally a level swash plate and working tail rotor that's not stripped based off reading other posts. I'm completely clueless as to what is going on after it took me two months to get this far.

Any ideas guys? Help a newbie out please!
