It's not the motor, it's the esc that will fail. And being Chinese electronics, there's no thermal protection built into the esc, so when the esc overheats to it's melting point there will either be just a puff of smoke when the esc burns out or it will catch fire... no shyt! I've heard it happened to several guys with the Chinese dump trks. that hyd pump motor runs from a dead stop.

Personally i think that a 4th valve is a brilliant idea and i dont see why other companies have not employed the same method?
It's b/c Eagle Machinery company is retarded, they're using a motor that's much too large for it's application... their solution is to dial back EPA to 19% instead building or buying out of country a properly spec'd motor.

Something else, the PRV that's in these Chinese models, the coiled spring is much too stiff & with the barrel so short - not a lot room in the 1st place for a proper length coil to allow the BB to move to relieve pressure & allow flow. Throw that piece of crap away & make your own with a longer barrel for a lighter spring so you can get a much finer tuned pressure setting & that 4th valve wouldn't be needed.
