I'd be pretty dang pleased with those numbers Chuck.
I'm at 2.8mpg @ 4200 = 26mph right now.
I moved the motor's up 2 holes. It was 2.3mpg @ 4200 =25mph.
I'm moving them up to the bottom hole in the near future.
I believe I can go up on the pitch too. 18.5's now, going to 20's. I don't have the money for prop's right now.
