Low rates -50%. Set it, fly it. Best, let him see what he is comfortable with and standby him when he is flying to catch his mistakes.

DenverJayhawk, I myself did not try out dual rates till I went to my second airplane. But it is not a good idea to set full rates for a trainee. Some airplanes are too reactive: you dont want him to doink it into the ground even without trying a loop. I saw this problem when I moved to a Tiger and very soon set dual rates. Its OK on a trainer to set full rates though
