Re: Patillo's Front Spinner Bulkhead and Catto's Latest Prop

Jim I read that rpm was down by 400 and I guess max power down also. Did you try for max speed at WOT? How did the max speed compare with your regular prop? I am experimenting with a Warp Drive 3 blade adjustable prop and looking for ideas. I have read that we get a 5% efficiency advantage with a two blade prop.

Kevin,

I hope the pictures help you. I took them like I said but the ones I
took weren't worthy of sending to anyone. Brad has a better camera.
