One of these things is not like the other...
It smoked a 36t gear. Where have i seen one about like that?
My tamiya double motor gearbox that i picked up for a future Bruder delta Cat has 3 per gearbox, the 115:1 ratio only needs 2 per box. Grab a razor and remove the small gear off it.
Then i noticed the pinion gear is also cracked, that might have helped bind and strip the axle gear. Let's see what other motors i've got... a SuperSlicks 1/24 Crawler green pinion is direct swap, and the motors fit in the gearbox.
Then i stuck 4 cells into the control, that's really slow. Probably don't need that steep of gear reduction.
