I was flying my Sukhoi the other day and when I do a stall turn it falls to the left to start out. Or if I dont give it a rudder command when I stall it. It just falls to the left a little. Also when I am hovering it I have to keep some right rudder in it a lot. Should I put a little weight on the wingtips?

try a little right thrust you would have to hang a pound on the tip you did check the lateral balance didn't you are you sure your rudder is centered don't go by the counter balancer mine is sanded a little off on one side

You should always laterally balance your aerobatic (all?) airplanes. You should also read the some trimming instructions to ensure that you have the correct amount of right and down thrust as these too will change the behavior that you describe. There is a trimming chart on the web known as the NSRCA Trimming chart-- try searching for it... Chip Hyde has also started covering these issues in 3D Flyer magazine. You can try posting this question in his forum if you don't have the mag...

Also -- remember that under low speed high power settings, e.g. hovering, you will have to use right rudder to compensate for p-factor and/or torque... Just how much depends upon your setup and thrust angles... This is something that I need to learn more about myself...

Thanks for the info. I will play around with it.
