This is already a question here, but i want to know for my scenario. My plane is going to be a Kadet MKII...engine will be a TTPro.46(hopefully if i can get one)...im a beginner, but a very quick learner(can be a curse sometimes). Which will be the best prop size for me for learning takeoff, landing, basic flight, then kicking it up a notch to some faster flight and flight maneuvers, all while keeping the engine from over revving.?? All help is appreciated. Thanks--Nathaniel
