Weird thing is, it only does this when a peddle turn is made to the left, never when made to the right, yet the right swings the nose around faster.
Torque. I had an R/C plane that was like that- right rudder did next to nothing, left rudder would almost put it into a spin.
It cancels the torque from the spinning blades, but it'll still have torque from the electric motor spinning away. Not much, but when you throttle up, it gets noticeable.
You should stick to fixed wing aircraft.
Fresh from overhaul - with the wife taping. Go figure. Good news is the only thing bent were the pylons on the body and 1 of the blades. The control inputs were forward cyclic, left rudder full with increasing throttle - the nose swung left and dipped about 30* low and got a ton of speed where it should not have. Had no roll control once it picked up speed on the way down - almost as if it went into compressibility.

Its coaxial, torque should be negated.
