After picking up a pair of Tamiya Terra Crushers for a bargain, I decided to convert one to electric to spare my neighbors the deafening nitro roar and bypass a pending transmission overhaul.
Transmission & Drivetrain Stripping out the nitro components was a straightforward process. Following recommendations on TamiyaClub, I looked into the Traxxas E-Revo gearbox. Unable to source the exact piece originally suggested, I opted for the complete E-Revo VXL transmission (Part #TRX8695), paired with a TRX5660 motor mount and a Module 1 pinion.
Custom 3D-Printed Fabrication To secure the gearbox, I designed and 3D-printed a custom adapter. While sheet metal or plastic plates would have worked, I prefer the precision of a printed part. After a minor measurement error on the first prototype, the second print fit like a glove. Note: Be sure to mirror the motor adapter design to get the correct orientation for the second side.
For the battery holder, I utilized hex spacers; if you don't have these on hand, you can simply print the screw-variant spacer instead. The battery is secured cleanly and simply using a standard zip-tie.
