(2) HV4.5 motors 1 is considerably slower. Worn out rotor?

My work here is done...

Still strange though, but I can only imagine that the system from ebay had been overheated, which killed the magnet. Re-manufactured escs means they are both 'new', as is one of the motors, but you are then left with the one dud motor, or rotor atleast. Thats my theory; get the remanufactured motor, then everything will be 'new', and hunky-dorey hopefully.
