Hi Big4D,
Just wondering if you had decided on a power plant and covering yet?
I built one back in about 1994, clipped the wing and used a .70 four stroke. Covered it with Sig Koverall, Stixit and dope. Tough covering. I once fumbled a 6" crescent wrench which landed on the wing directly between the ribs and never punctured the Koverall. The power of the .70 seemed to be a good match to that plane. Good luck!
