I think we are pretty committed to OS and the likes because of the known availability and the reasonable cost. I think one ting you guys have helped us think through is that the challenge should not be so much about the engine but the design. if the engine puts out enough power, in terms of the contest it doesn't really matter if the planes are doing 115 or 130. Take the power you have and do the best you can.

Can anyone tell me the typical rpm gain by removing the muffler baffle?

Thanks!
