Hi All, weve been snow/ice bound here in Atlanta for the last few days. Got so much done on the Pitts, Im outta Argon! and no hope of getting more for about a week.

I thought someone might be interested in this. Here is a picture of the torque tube as it came with my project. Can you spot whats missing? Its kind of odd, since the fuselage was built very much to the plans with the exception of a more reclined seatback, which I like, and this torque tube, which I dont! I dont have any good info on the history of my fuselage, so I must rely on careful inspection of every part.
I was flipping through the IAC tech tips manuals, and in volume 3, found a sketch of this torque tube. It looks like someone showed up at Fon Du Lac in 1981, and was turned away duringsafety inspection for this very reason. The good folks at IAC found this serious enough to include a sketch and special mention in the newsletter.
Of course its possible there weremore than one that were built this way, but I cant imagine why. Seems a bad place to try and save a few ounces.
Anyone ever seen this before?
