That would be nice. Let me know when you are done with it and I'll pay the shipping both ways, of course. If I find a suitable around here before then, I'll let you know.

I'm in need of a test prop so that I can achieve cruise RPM on the ground for engine tuning/test purposes. I am having problems in the rpm range that I am only able to achive in flight with my current prop. I need a prop that is suitable for equal to or less than 160 hp, and turns in the clockwise direction on a tractor airplane as seen from the cockpit. I only need this for ground running with the tail tied down and at speeds not to exceed 2500 RPM. If anyone knows of such a prop being available for my purposes, I'd appreciate hearing from them.

I finished this prop today, Brian. Nothing left to do but put some paint on it. It is 90mm square and 70" long. The theory is that I will be able to enter the RPM my engine drives this at into an equation, and it will tell me the HP I'm producing.
If you've got a few days for me to finish some test runs, I could certainly share.
On a related note: I modified the previous prop I had carved to give it more pitch. My airplane moved under its own power today. Not fast, or far, but I did get a chance to use the brake 8*)
I also got a smooth idle between 850 and 900 RPM.
I've got to get my generator sorted out, and then I'll be ready to put the cowl on with its radiator so that I can have some extended tuning runs.
