G'day, Its about the best ARF you can buy! A real stable fun-fly. Use a .72 or .82 4 stroke for power. Side-mount the engine, run exhaust pipe and silicone exhaust extension tube through bottom of cowl. Take a Dremel and open up the bottom of the wheel pants.Tires can brush up against the inside bottom and chip them. Use remote fueler and ignition so you dont mess up the cowl. Homer Simpson fits right inside cockpit. You'll like this plane a lot. Seeya, MM
