For those of you who have upgraded to a big block motor and a better ESC like the Mamba Max Pro, are you running into drivetrain issues with 4S+ power? I don't mind spending money on an upgraded motor & ESC to handle big power, but I don't want to be replacing other drivetrain parts all the time like the differentials, etc.. I don't want to have to be constantly replacing parts because it's just too much power. I understand more speed equals bigger crashes, but I know that going in.
So how are the drivetrains holding up to big power? If they're not, what aftermarket solutions are available? Should I just stop at 3S? I want a reliable rocket.
