Are those cross beams completely detached except for welding or are they from the same sheet?

Cool!

-q
The outside rails are 4" x 4" x .187" aluminum box, the inside crossmembers are 2" x 4" x .125".

The frame as shown plus the square plates to cover the front and back weighed in at 22.3 lbs, 7 pounds lighter than last year!! Last year the entire frame with chain, 4 CIM motors, transmissions, and wheels weighed in at 53 pounds.

Yes, those crossmembers are a seperate piece that get riveted on every inside corner then welded along the riveted bracket on top and bottom.

Thanx!
