Well, we have a really cool bumper design, which allows for us to never need to take off the bumper (unless of course we really need to). Basically the little slits underneath the triangles are bumper mounts. then we're going to have like a pin or something that keeps them in place, along with anything else needed to hold them in place. As for the actual bumper, we get one bumper with the two color schemes sewed together by a local upholstery business, put some velcro on them, and then we just pull the fabric off the velcro, and bam, its now the alliance color that we changed it to. It's kind of hard to explain, but if you see 461 at a competition, swing by and ask about our bumper system.
The sheet metal is 1/8 in. thick and weighs, based on my memory from the CAD's iProperties weight analysis, somewhere around 4-6 pounds

hehe... i think i know who is doing the sewing and where you got the idea from... keep in mind i was on 1747 last year...

Klumpe's embroidery?

copy of 1747's 2010 bumper? (your description is an exact match of what we did)

busted?

anyway, for the bumpers, you have nothing to worry about, the bumpers work great as long as you size them right; having to un-staple and pop in slivers of pool noodle to widen the gap between 2 units on practice day is not fun at all... but the flap part had no issues at all.

drivetrain looks very pretty... nice job!
