MFU keeps shutting off!!!!!

[Brel]

have you got both rear axle turning in the same direction, because they could be fighting each other for grip and causing the truck to stall, thus over heating the ESC in the MFU to cause it to shut down, I suggest you put the chassis on blocks and the try running it to see if the axles rotate in the same direction, if they are rotating in opposite direction then all you have to to is flip one and that should solve the problem of the truck stalling. if they are both going the same way then I have not got a clue, I must admit when I built my scania R620, I installed the rear axles so that the ran in opposite direction LOL
