Hi Martin ,
presume you mean the small version – there is a larger one as well !
Two of the little flat motors – (not the 140 type) provide enough
power – or two of the type that power servos . You can obtain a twin
motor esc type setup from the component shop – only draws about
2 amps so a receiver type battery pack would be enough.
Running parts are provided in the kit – good enough but personally
would fit oiling tubes to the shafts. with such low power you will
only need a piece of tubing to connect the motors
If you go into the MB Mayhem site and search for Billings 101 Lifeboat
there are a lot of build threads you can run through for more tips
