I'm getting ready to fly my TF Corsair 60 gold edition and wondering what would be the best prop to use. I have a 13x6 and a 14x8.The plane comes in at 9 pounds, and I have a super tiger G90 on it. So what's the best prop to go with? Onthe Corsair box it says with the super tiger engine to use a 13x8 or 14x6 and nobody in town has oneeither size. also I can never rember the difference between prop size & pitch, can someone explaine?
