Im flying a Showtime 50 with a saito 91. Waht would be a good prop to have the best of both worlds - pattern/3D flying? I was using a 15x4 but seemed to be too much for the engine as it was EATING fuel. Ive changed to a 14x8 but plane has a much longer landing approach. Im looking for some speed and alot of thrust. Does anyone have experience with Showtime 50 and saito 91? Thanks!
