I got mine flying with a Saito 100 GK and it is a really sweet flying airplane. Plenty of power for vertical and all aeroatics. Really sounds good with Saito just loafing along below half throttle for just playing. I did reinforce my gear and after about 20 flights have had no problems. I used 3" hi bounce wheels and that really helped alot on grass.
I put the dummy radial in with all area cut out between the cylinders and have had no heat problems. I did open the intake and exit vents molded into the cowling.
great flying model. It is definetly a keeper.
