Transfer case done along with drive shafts. Also made a attachment plate for mounting motor to gearbox. Waiting on some gearstock to make a one piece coupler from motor to gear inside gearbox. Went with a fairly low kv motor that is sensored for easy start up and soft transfer of power to drivetrain. Using tekin rx8 esc with a 1400kv motor on 3s voltage. That gets a reduction in the gearbox of 4:1, 4:1, 3:1 then into transfer case all 1:1 then into axles with a 3:1 differential. Very similar to the haul truck. I think I used a 1900kv motor on that set up. With this machine I’m more looking for the motor to spin up closer to full speed while keeping machine slow and smooth power.
