Default 1/8 buggy: twin low KV motor build

check out this great built !

crazy germans ! twin motor mbx7r eco for racing !
https://www.youtube.com/watch?v=WYXULzXSn30



setup : twin 1/10 motor, twin 1/10 esc, independant adjustable front and rear braking, speed ( for overdrive ), from the RADIO !



very good weight distribution , no more center diff, man it sounds like the future !

the builder says it drives like a nitro : same smooth Rolling

note: the guy's name is Werner ; it has nothing to do with my channel, "Werner's bunch of tricks " !

Man that's cool. I've been thinking for quite some time it would be cool to have 4 small motors. One for each wheel. That would eliminate all the diffs and driveshafts. You could program the diff action front to rear and side to side without changing diff oils. You also eliminate a lot of gears, bearings and other rotational mass which robs power.

true but 4 motors would add non suspended mass + they would eat the dirt like crazy

You could put 2 motors in each gear case and still use driveshafts. But no center shafts and no diffs.

But sadly, programming the motors for diff action would surely count as an "electronic driver's aide". Doing that would open up the ESC for all kinds of yaw control and turning aides.

That Mugen looks like 10+ pounds. Good luck with that.

10 pounds?
I'd say it's the same weight or slightly less than a standard setup.

I also think it is the same weight as a regular mbx7r eco

in my opinion :
2 lighter motors + 2 light ESC = regular motor + 1/8 esc + center diff

I've seen this done before, years ago by a local.

Outrunners don't survive long in a 1/8 buggy.

Not hub motors, but one for each wheel.
