TIGREJOHN, I found the CG in this article [link]http://findarticles.com/p/articles/mi_qa3819/is_199801/ai_n8803505/pg_3/?tag=content;col1[/link] , they recommend 3 1/2 inches from the LE, although I'm not sure it would be the same for the kit version. I'll probably grab a few props to try when I take it out but I think you may be right tIANci about using the 11 in instead of a 10in. One thing I have left to do is fasten the wheel pants to the landing gear to keep them from moving around. If there was hardware for this I've lost it. I was thinking of punching a couple holes in each and using some wire to twist around the gear, any better ideas? Thanks again for the help fellas.
