One problem I had right off the bat was assembling the Yellow Aircraft wheels. They are a two peice aluminum hub that screw together to sandwitch a tire of foam. I finally figured out the following procedure to get the job done. Posted for reference if anyone has this trouble.

[ul][*] unscrew the two halves of the wheel hub from each other [*] test fit each side of the rim in the tire, this stretches the foam a bit and will ease final assembly [*] grease the threads of the two halves. [*] grease the surface of the *spokes* side of the hub on the inner surfaces where it would come in contact with the foam. dont' do this to the other, solid surfaced rim half [*] cut two wood dowels of about 1/4 inch diameter to a length of about 1.5 inches each. these dowels need to fit in the spokes of the hub [*] place the two dowels vertically in a vice, sticking up from the suface of the vice about 1/2 inch, and as far apart as possible while still being able to fit the spoke half of the hub onto your new "spanner" [*] insert the solid half into the tire, then the spoked half, then work them together until you can get the threads started. Be careful and dont cross thread them [*] place the assembled wheel spoke side down onto your vice/dowel fixture [*] grip the tire and solid hub half with both hands and begin to tighten clockwise
