RE: OK Suprafly 25
I don't think there is space for a front retract. Mine is a tail dragger with Supra 20 retracts. I didn't even put in a tail wheel - just a skid. With the long tail, I find the skid sufficient for ground handling and also it saves weight and drag.
Mine has six full-size Futaba servos - 2 ailerons, retracts, engine, elevator and rudder. The OS32SX with tuned pipe really pulls everything along, believe me.
