gearbox
Just back from the LHS with a MPI gearbox that can be changed between 2, 2.5, and 3 to 1 ratios. Also have the 9x5 folding APC prop. We'll see how that goes.
I'm ready for a different prop. Those little Gunther props started flying off in flight today. I guess the rubber spinner/bushings were getting a bit too much heat.
