Mamba Max in a Savage?

The currents you are talking about are vehicle and gearing dependant, and it are peaks.

a 100A esc can handle higher peaks than the 100A as well.

Well true, but the point I was trying to make is that the 7xl will draw more current, and we are talking about a heavy Savage and not a light buggy. It may work, but IMO given the app, its too hot a motor.

I would think you would really begin to fight heat issues with the esc which already requires a fan to run a higher turn motor in a lighter truck. Who really knows, AFAIK no one has tried it. Is it worth the $ to risk it? I can't recc it.


EDIT: N/M, my reading was off.. I would think a 7xl on a MM in a buggy may work. May still need a fan tho.

@RTS:

Most of the driving has been on 14 cells, 15 was done as an experiment on a speed run, but the tranny case was damaged during (the bearing hole for output shaft got loose and wobbly) and I haven't got it fixed yet. Outside was ~68F and the esc was ~115, but only ran ~10-15min before breakage.

I used a 40mm and now a 25mm and the temps have stayed low on me. I was using the 40mm fan driving hard in 80-90F weather in Aug and temps stayed low. Gen no higher than 125F, usually less, so I put on a smaller 25mm fan. Temps went up ~10F, but a still very safe range. Caps got to ~135F as a fan no longer blows on them. I'm certainly satisfied with the MM for mine, but YMMV.
