George,
6000RPM is the maximum I can get, which is very close to static with my setup at a MAP of 28" and WOT. At that RPM the prop seems to get into all sorts of things, just what it normally does under these conditions. In addition, the engine is not dynamically balanced yet.
The PP is a round hole with 1.5" diameter, beeing effectively about 40mm considering the exit roundings. Opening timing is as in the LeMans engine.
I don't think I will ever do max RPM on the ground, since running with a prop is the only power runs I can afford to do.

Richard,
Good one!
It would seem ( from the hand signals) that you ran the engine to 5,500 or 5,600 RPM. Have you had it to 6,000 or 7,000 rpm yet?
What size PP are you using.

The single rotor I am going to run is peripheral port. Can also talk about it.
