Thanks Gail,
You know the drawing throws you off, at least I thick. That lower front face looks like an angle. The way it blends into the outside edges. But now after seeing it there is no angle. The side tapering gives that effect. Your right, I am a persistant SOB. I have it in my head I will I will I will. Someone mentioned on the Yahoo the the cam should be mirrored so it will run clockwise (as view from the pilot seat). There are a lot of European engines even to this day that run counterclockwise. Today, I went to the hobby shop to order a pusher prop (10x7- 11x6) so I can turn backwards and see if the airfoil will work, by the pics at Tower Hobbies it look like it will.
Talk about advanced planning :big: a little incentive and figure out what the hub dia should be and do I have to reverse the cam.
