Thank you Mike and Tim. My friend used some of the original aileron material for short pieces of flap. He might have cut down the aileron area too much. I'll seal the hinges and increase the throw to start with. The rudder area looked too small to start with but it was already hinged and tapered so I haven't increased the area of the rudder yet.

Models such as the Telemaster and Sig Kadet and Mk.II have been known to have adverse yaw cancel out the roll of the ailerons. A friend of mine's Kadet (original kit) would not turn with aileron and elevator inputs for just this reason. We had to drill new holes in the servo output wheel that made the high aileron go much further up, then it did down in the opposite turning direction. In other worlds full right aileron would provide large amounts of upward deflected aileron on the right wing with not as much throw downward on the left aileron. That straightened out his problem of not being able to roll into a turn using just aileron and then compensating with elevator in order to maintain altitude. I hope that was understandable.
I agree with the other posters that the Telemaster series models have skimpy control surfaces to begin with.
