I took the first real runa nd it went well, but I had to run the motor tucked all the way in or it would ventilate, I have a spare 4 blade on her and I'm thinking about going back to a stock aluminum 3 blade (my original was bent in a wreck). Can an aluminum prop be cupped a bit? if so how much does that usually cost? Think this would help the issue? Other than that I think I need some tabs, I need her to plane quicker and stay on plane at lower speeds. I was also hoping this would let the TnT to be used to adjust running angle instead of having to be tucked all the way in. I have some things worked out in my head, I was just wondering what you all think? here's some picks.
