What I learned from that post was the 1.8 ratio. I don't think I had heard that before. I can get that with the std ikara. I though have been looking at the broad blade as a way to get full motor flights in a small gym. I am worried about beating my plane to death in the rafters or worse bouncing down wall. I did though get some good flights in last night with the std blade winding to 80 percent. But I did have the weirdest accident-winding ring broke and motor snapped back and sheared prop spar. Oops. Need to make sure now I have two props of same weight and pitch.

Please re-read my post. I said:

Jeff, how do you actually make your own thrust bearings (like a Harlan Penny Plane thrust bearing)?
