i think one of the biggest problem was that it was way over geared as i never used but maybe half the speed of what it was geared for.
the reason i have been thinking about going dual mmm and motor is that then i would still have brakes and reverse. but i havent found another esc other than mmm or tekin rx8 that are capable of high load and have those functions.
have actually been thinking about if using dual setup i will make some kind of differential and run the motors by seperate spurs so the motors can run indipendant speed but still share the load 50/50.
lol i'm pretty good at fabricating stuff like this but when it comes to calculate the brushless setup im kinda clueless
