I broke my TT 46 pro with the prop I was going to use for flight. If you use a prop on the extreme low or high end, just take it easy on the engine for the 1st tank of break in, keeping the RPM's low to middle of the range. On your second tank increase, but keep it rich. Great engine with 10-15% nitro and any range of prop recommended.

Got yourself a great motor. Aside from the TT 46's that I have also an OS 46. Ibreak em in and fly with MAS 11x6 props. I'm no expert but this seems to be an excellent size for these engines. Good luck
