First MOA question

[Hoser1869]

Just got a XR10 roller, and i have it temped together with a single ESC no dig (till i can get a 2nd ESC) and when i go up my plywood/carpet ramp the front tires spin before the rears, its exact same gearing front/rear. i know this is because the rear tires have more load on them and require more voltage to spin. My question is will dual esc's fix this? or is this just the way it is with a MOA?

Dual escs will fix that.
With one esc its common to want the front to over speed the rear,this way the front helps pull the truck over.
If the rears spin first it tends to want to flip the truck on its lid.
Welcome to MOA and lets see this puppy.

i understand the want for underdrive/overdrive, i have it on my SCX10...but with MOA each axle has different load on the motor depending on the terrain/incline...with a shafty the driveline makes the axles common to one so the load is the same. So on an MOA going forward up a steep incline there is more weight/load on the rear motor, so through your throttle finger lets say you're giving the the motors 2 volts the front will spin before the rear cause the rear will take more voltage to spin cause of the weight, so will dual esc's with mixing fix this or is this just the way MOAs run?

also i tried going up it backwards and same thing the rear tires spun easier then the fronts

With dual escs and proper mixing you can mix in or out under/overdrive.
you could even make the fronts spin clockwise while the rears spin counterclockwise.

Weight transfer is a large part of moa. You may be lifting the front of the truck due to shock and link geo set up.
Search squat anti squat.

Good luck and have fun.

2 esc and radio that allows mixing with function-specific MOA (I use the sanwa mt4) and see how it changes ..
