Sure thing Mr. Tharpe. I wish I could add files that aren't JPG, TXT, or GIF, but I can't, so I'll send it to you via e-mail.

BMatthews has a good point about keeping shape and the tube dimpling. Depending on the alloy and temper, thin wall aluminum tube can be easily crushed or dented, so transportation can compromise the structural integrity of the tube (also it can become deformed with regular use).

As for the equation I posted. That is the equation for the pull-up radius of an airplane based on velocity and G-loading. "V^2" means velocity squared, the "^2" means "squared." If anyone wants any more nifty equations, I'll be happy to post them. There is also an equation for turn radius for those of you pylon racers.
