Does it sound like maybe my prop just isn't right? Maybe if i went to a 3 blade ground adjustable prop it would solve all my problems? I don't know how else to get the performance out of it that i should be getting. My friend has the same plane, except his is on amphibious floats, and his plane flies faster than mine, even with all the drag. The only differences between the planes, other than the floats, is the gear box and prop. He is running a C gear box, and a 68" 3 blade Warp Drive prop. I feel that with mine not having all the drag of the floats, mine should perform much better.
