Before you do anything, try the stock TT Pro 46 with a 12x4 prop. I was amazed at the increase in RPM and thrust. It really turned up quick.

It was slower (due to the shallower pitch) so watch your turns on final (ask me how I know) but overall, I really liked that combination. Never pulled the baffle. Didn't feel a need to, but that's just my personal preference.
