Hiya, as far as I know Gimson's start life as drill motors. I have two of the older GR01's running on a 2x12 Sabertooth and it's been bashing round the house great for 6 months

The main gist is that there are ESC's for each motor and you sort mixing out externally, or you can get something that does it all in one box like the Sabertooth. Different setups work better for different people.
