OK, here are the props I ran,
A MasterAirscrew Scimitar 9x5S rpm====12,100
A Taipan 10x4 rpm================9,200
A Graupner 10x5.5 rpm=============9,000
Idle==========================3,100
I only got a single outside photo to take, its really difficult to take them in the fall, as you can see. This one about two clicks from the peak. I don't seem to have a 10x6 of any brand. I think you can take a look at the Taipan and see why it made only 9,200 rpm but that dude makes some serious wind.
The fuel was Davis ABC blend.
I'f I'm able to sort things out and get those kind of numbers I will be a happy camper
