Matt,
Good to hear of your success with the custom 17-3/8x12.
Maybe sometime before the Pocono contest I can head down your way on a nice Friday to compare results and swap props. I plan to fly at Black Dirt this coming Friday, before the Conyngham event.
Bob,
This prop is more load than the 17x12 apc but now that the engine is showing signs of full break in, it works pretty well. In your Focus set-up, you probably don't need any more prop than what you are using so I wouldn't change anything.
Throttle curve finding was interesting. I can't imagine why I never looked before yesterday....the curve had throttle accelerated at low settings rather than retarded. Once I got that curve better, the engine improved its character immediately. The original curve looked like a hook, curving to the top of the screen on a JR tx. The present curve is curving slightly down...nearly a straight line actually.
We need to tame the noise signature
