Made a new ET48.3 length rear bulkhead brace with and integrated dropped ESC mount and thought I would share. I could probably drop the ESC another 5mm with some new standoffs but was feeling kind of lazy. While I had it apart I installed the 48 tooth steel spur gear and hardened steel drive cup. I had to mill a slot in the chassis to clear the spur gear (it does not stick below the chassis) and made a secondary top brace as I had to open up the upper plate to clear the spur as well and it was starting to look thin. Next up will be Cooling Fan mount for the motor that ties into the M2C chassis brace.
