The use of thin plate for a module will allow it to flex a hefty amount, and deflection isn't good. A tiny amount as small as .125" of deflection will take your wheel's contact patch down by somewhere around 60%, depending on the size. If it's not rigid, you lose HUGE amounts of efficiency when turning.
As far as strength of the Window motors, keep us posted on how they do.

well the box(mostly inspiriationaly)
actually it dosent all have to come apart....the way we built it, the motor is bolted to the outside of the box, the hub is attached to the output gear, the hub is attached to the wheel, and a 1.5inch 3/8th bolt is put through a bearing which is then bolted to the other side
to remove the entire motor and wheel and replace it, takes about 3 minutes
yeah, the plate is pretty thin, we are waiting for comformation if a local machine shop can make us some thinker ones(say 1/8inch alluminum?)
pretty much, it was built to be as cheap and simple as possible(as i said its our first time Not using tank drive) we're feeling pretty ambisious this year
ps.. we have 4 window motors for driving the wheels, and we have 2 other motors that came in the kit(not sure what they are, like a bigger more metalic version of the window motor?)
