Thanks Bob

This may change but it is what I have in mind. Graupner 10.5x5.

Dave, I have Master air screws on them know, they are three blade 9x7, the best rpm is 9600 on one engine and 9400 on the other

That makes perfect sense, I have picture somewhere of one of mine turning an 8x6 three blade at about 11,400, too fast to suit me. This is where my .30's are going when I can afford the plane.

I have ran these with a 9x6 single on the test stand and they turned back door of 12,000, as you say way to fast

Bob my 30 ran 10500 with a mas classic 10x6 and it ripped the prop tips.

Dave shame on you for posting a twin with os engines on it and two grey apc props!!
