While you're waiting for whatever RC gear you're getting, Clive, I'd take the skates off the motor block, along with their springs, and put them away in the spares box. Then take the bottom plate off the gearbox, drop out both axles and remove the carbon pickup bullets and their springs from their housings (more for the bits box!). Refit the axles (no need to worry about proper positioning in relation to one another, as you have no cranks or connecting rods on this one), and refit the bottom plate. Your gearbox will now be completely isolated from the track, so all you will have to do to connect your RC gear up to the motor will be to connect the two power feeds from the speed controller to the OUTER two pins on the gearbox, which go direct to the motor terminals.
