In considering other trucks for direct drive conversion, just remember what we've ran into on the cogging issue. I think that line that you can't cross is somewhere about 4 inches of roll out per turn of the motor. Vehicle weight affects this I'm sure.
But more so, I believe it also has to do mainly with the level of EMF pulses that the ESC MUST get from the motor to start properly. More on this later. |
The MT2 is pure 1/10 scale, no optional 1/8 diffs. The diffs are actually a weak point on it, even with the optional hardened diffs on the 18SS kit (which are the ones I started with). However, aluminum diff housings have fixed that issue for me, in combination with the hardened diff gears.
My motor is a KMS 4120/06:

I get these at a discount 'cuz I work there. It uses a 6mm shaft, so I have a 6mm steel rod that I will turn down to 5mm where the dogbone cups attach.
Only problem that I have found with the MT2 so far, is that the stock chassis is pretty narrow.
