The syncing thing is easy enough, just short two motor wires with a single sub-c cell to align the rotor to a certain posistion, repeat for the other motor ( same wires ), then mount the motors & pinions + mesh to the spur without rotating the shafts before they are meshed. Once meshed, they will stay synced until one motor is un meshed and the shaft rotated freely of the other motor.
