I am currently upgrading my turbo vee 2 to a speed 600 race motor and a esc to handle it. My question is what size prop would be a good starting point? Right now it has a 32mm with 1.6 pitch and a 550 motor (27 turn stock) and I'm worried the faster motor will cause cavitation with this prop. I have also got a new 4mm drive shaft so finding a prop is no longer a problem.
