Default RE: Staining on top of piston
""Engine is running great on the ground, around 8700 RPM""

it's just M.O., but I would think if you went up in prop diameter and get that RPM down a bit/ around 8000 you will get more out of your motor,, if you don't have room for a larger diameter go up in pitch..
