Bobby,

I didn’t catch what you mean = by,” now I can ground run 36" MP at 6800-6900 rpm with the = prop set for high rpm. I can run 7500 rpm at = 31-32".”.

You are running a higher rpm with a lower pressure?  = Typo??  Did you mean high pitch?

What kind of prop are you running?  Sounds electric = inflight adjustable.  IVO??  Or big bucks MT?  What diameter and = number of blades?
