get more speed from the same size planes without sacrificing vertical.
THAT is what I am looking for. I read that post, and really since I have Zero knowledge of re-working an engine like that, it doesn't really do me allot of good. Guess that's why I am looking at the best overall "out of the box" engine. I was lost after about the second or third post. I understand most of what you're doing there, though I have no clue how nor the equipment to do so... I also read a thread somewhere talking about some problems with the MVVS .15 which is probably some of the issues you were correcting. How much would it cose to send an engine to someone and have them make the corrections like that ?
