Hi, Here's the situation. I have been using a 10 x 7 prop and am happy with the performance. Then a friend with a static thrust meter measured and compared a 12 x 6 prop and found that the larger diameter prop has nearly twice the thrust.
The problem is that the larger prop tip will be almost touching the ground. I don't want to make another landing gear.
I wonder if a 3 bladed prop may be the answer and if so, what diameter and pitch to match the performance of the 12 x 6 prop? Or could I drop the prop size to an 11 x 5.5 that I happen to have?
