Jeff Kemp. Correct. Heck of a nice guy.
His plane had a stall on the bottom of the triangle. You could see it, and I'm sure he felt it. I had something similar with a somewhat overweight Super Clown. I backed off on the flaps, and it sort of stopped doing it. Still doesn't fly worth a darn, but it's handy on balloon bust days. Has a sandcast two bolt Fox 35 on it, with what I think is an Austin needle valve assembly. Hard corners are not what it does best. Haning in the little guy's bedroom is probably what it does best.
Anyway. Not sure of the details of Jeff's Gee Bee, but I do recall a roll of plans somewhere along the way. I think they are very cool, but like a P 51 - not the best thing to model. Hey, what do I know. We'd be watching full scale modified Twisters with logos from watchmakers and breweries and database companies if I were in charge. I'm number 2098 down on the list of being in charge - we're safe.
And if someone runs into Jeff Kemp - please let him know I said hello.
