RE: Best engine for a Bobcat 50
OS Max 50 Hyper heli motor with a Jett muffler set up for pusher prop use. Exhaust faces toward the rear of the plane. With 10x6 apc pusher prop gives 16,500 rpm on the ground with no overheating problems and lite weight. This is an expensive set up but works great with 30% nitro heli fuel.
