Both motors can be run together for going straight, or can be run separately for turning corners.
3 speeds available by clicking forward or reverse buttons (one click slow, two clicks medium and three clicks fast).
Has a stop button and an accessories button eg for a horn.
Picture below shows the small hand held remote unit: (picture on right is rear view it uses a small AA size 12v battery, may be a bit hard to find when it needs replacing)
There is one controller unit, that has output for both motors. I can only get controllers for brushed motors at the moment.
Controllers can be 24volt, 36volt or 48volts.
Remote control hand held device and controller unit for two motors come together in the kit.
