Default RE: Need a prop for OS 25FX

Try a 9 x 6 or so to start. You'll have to try different propellers to see which one will give your model the best performance. Also, please note that any time you change propellers, you will have to retune the pipe system. You cannot just bolt on a tuned pipe and expect good performance...you must get the pipe tuned to the engine/prop/fuel/airframe combination.
