I've been flying for a while and recently crashed my Sig Sr Kadet. I still feel I need more practice with landings on a trainer, although I have other planes to fly. I guy at my field is selling a 3 channel sig sr ready to fly for $225. Does anyone think it would be bad to fly a 3 channel trainer after using a 4 channel for the last year? I would set it up so the rudder is on the right stick.

Any opinions appreciated.
