I have one too. I bought it to play with and to use as a trainer for my kids. I put a Saito 72 on it and it has plenty of power. Fun toy and very stable. The tail wheel does suck and I put a DuBro on it bent the wire back and attatched it to the rudder with a 2" piece of fuel tube. Use some good fast servos on the Elevator and Rudder.
