Default RE: Thrust Figures For Norvel .049 and .061

If you intend to pylon race flying fast is your concern not thrust, torque or horsepower. Your plane and your purpose dictate the right engine prop combination. Fuel consumption will go up with rpm along with wear. A high drag plane like a Clancy Lazy Bee flies slow and requires more thrust. A larger prop turning at 17K will produce more thrust, lower fuel consumption, and less wear. That little low drag delta will love a small prop turning 30k. What plane do you fly?
