Bandangle,

You have me a little worried about my plans for the 7-77 in the 77 inch Stearman. I just laid out my plan with the fuse in take off attitude and measured from the center of the engine to the ground. It is about 12.5 inches. A 22 inch prop will have 1.5 inches of clearnce. The prop on my 1/6 scale Waco clears by about 2.5 inches in take off attitude and I have never had a ground strike on take off. I am hoping that the 7-77 will like a 20X12 prop.

I am also skeptical of the finished weights as advertised as they always seem to turn out a few pounds more in my hands and never less.

I have not reached the point of no return on this project yet even thoughI will soon have a full kit and plans, so I will be watching this forum closely.
