Hi Jim:

Actually two of them showed up at an early VSC. Not sure about the builder of one of them, but Jim Armour had one there, and it flew pretty darn well for such an unusual design.

If you are interested, I have two sets of full-size plans for that model that I's be willing to part with.

Later - Bob Hunt

I may be wrong but I think that I remember several posts years ago about this model and having structural weakness problems with the wing?.

Seems to me that the one I saw at VSC folded in half.  I don't remember who had it, around 2008.  Interesting design, like a lot of Jack's.

Yes, I remember that too. I'm sure that a little re-engineering of the construction could easily overcome that problem.

Bob, would you be willing to make copy's of the plans?

I have built 3 of them. Mine was one of the three at I believe VSC 3 or 4. Jim Armour's won the concourse award that year. 1st one died when  the Fox 35 died at the top of the wingover and it fell out of the sky, 2nd died when the wing folded at VSC 6or 7 years ago. it was damaged on landing at my home field in Albuquerque and the I Beam was cracked. Third hangs from my garage ceiling signed by Jack Sheeks. Having suffered a heart attack, a double bypass, been diagnosed with Parkinson disease, and been operated on for cancer, all a result of Agent Orange exposure in Vietnam. Don't know if I will ever be able to fly a pattern again. I Might bring it to a VSC and get somebody to fly it for me as it is neat looking when flying. Fun build and does the pattern reasonably well when flown by somebody who can fly worth a damn. Will send pictures, both covered and uncovered if you want them. Structurally it is sound. Burt Brokow flew a borrowed one at a VSC 3 or 4 years ago and did OK.

Jim, Build one. They are a fun plane, Don't know about tip stall and not sure if I would recognize it if I saw it Did not learn the pattern until 1990 and never progressed beyond Intermediate. It is built upside down so the outer portion of the wing is level in the jig. As a result the tips and the fixed portion of the flaps are level and alignment is easy using a bubble level. One of the reasons I love I beams. The tricky part is the tail, Again, a jig is the only answer in order to get them aligned and correct. Reinforce where the Hor Stab is joined. Keep the tail LIGHT. An OS 35S is my engine of choice. If you have not gotten plans, let me know and I will make you a copy of mine. Got them from Flying Models many years ago. Would love to see a picture of it.
