the race is on, prop size needed!
i need some help with a prop question, I just purchased a 40 size pole cat and using a os 50 for a powerplant, what is going to be the best prop for speed? Another member raced me last fall with a sundowner 50 size with a evo 52 and beat me up preatty good! I must win! I do have a macs1 piece pipe i may sneak under the cowl for increased rpm and less weight but need a great speed prop.whats your thoughts? I am trying to keep the setup similar to his, I know i could but a Jett engine but it wouldnt be fair.
