Tarmo 3 dual motor upgrade

thingiverse

Welp, it finally happened... Dual motor upgrade for the TARMO 3, by KrisCubed. This converts the rear chassis to be compatible with motors on both sides of the rear driveshaft. Both motors sit inside the mounts, which had to be designed to sit on the opposite side, and then the gearbox also had to change. This means it has 2 input shafts, and 2 input gears, that mesh into the normal output / split gear. Good upgrade if you feel like you need more torque with either a higher KV motor, like 2200kv as I am running, or just 2 of the recommended EMAX GT2215 09 1128 KV motors, which I did for about a week. One problem may be that the motors will need a higher rated ESC (probably 60A or higher) ***Would not recommend using the torsion spring, just print driveshafts in a flexible material such as solid TPU, PLAflex or nylon Still uses original bolt holes don't hate on me too much
