Cootertwo,
I think your Sukhoi is an early Cermark. I had one also and couldn't figure out who made it either. Finally did though, if I remember it was a Cermark. You are correct about being on the ball with it, it snaps worse than a Cap232 if your controls are too high and fast. Just keep the speed up until you get the hang of it and it will treat you right. I was a slow learner.
