Fred,
The Grey Ghost is a fantastic ship. It was one of the few stunt ships, I saw Larry fly it at the Perth Amboy meet, it grabbed my attention and held it for the whole flight (at the time I was 14 and didn't fly stunt). Larry flew it fast and very crisp, the corners were blinding. I believe he had a Johnson 35 in it and used all its power, may have been on 62' lines. This wing is similar to the wing used in the El Diablo, kinda a pre-Ibeamer. I have built the El D and still fly mine in OTS.

My advice is this wing is very good as is but don't use MonoKote or any plastic type covering, use 4 - 6 mm silk or medium silkspan. Don't use a clear finish on the silk unless you have a very good UV resistant clear (not dope). I would build the spar first and add a layer of 1/64 plywood to the top and bottom, apply with slow epoxy and weight it down to cure. Round the leading edge, use hard balsa for the stab, seal the hinge line.

Don't know what you have in mind for power, but this is not a 4-2-4 kind of ship. Something like a Fox Combat 35, K&B Trop 35 on a 10x5 would do well or an OS FP 35 - 40 or even an OS FP25 on 9 1/2x4. If using a muffler on the Fox or K&B cut the prop to 9 1/2" diameter to reduce the load heat. Use good fuel and enjoy.

Yes, the Lieutenant is another very good non-flapped ship. It also was not a 4-2-4 kind of ship. One thing with this ship is to round the wing leading edge as much as possible for smoother level flight and kept the stab leading edge as sharp as possible.

Fred,

Are you going to put that GMA ABC Fox 35 in the Grey Ghost that you got from me?  Tom
