as for the wires,thats something we'll have to figure out later


ps.. it may or may not be, based off your cad you posted awhile back.....

I'm confused as to how this could be based off my CAD. I've never done a direct drive, nor would I ever consider it. If something breaks in this module, the entire thing needs to come apart to change it.

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.
