RE: Engine Break-In
Yeah I had intended to go up to the 11x7 later on but seeing as Id had troubles and had to go back to a 10x7 for a while Ill stick with the 11x6 at 12000pm static now. Id hoped Id get more than 12000rpm but its plenty enough. I got 13300 with the 10x7 though, but the 11x6 is better in flight I feel.
Just keep it rich for as long as you can stand flying around at slightly reduced power, if I had to do it over again Id keep it really rich (about 1/2 to 1 turn rich will give about 200-500rpm less from my testing) for at least 10 tanks before leaning it out.
