550 motors on 2 or 3:1 reduction gearbox (Model Slipway can supply) and run on 12 volts.

speaking of gearboxes, anyway of cutting down the growl of them?  obviously straight cogs they wont be totally silent, but if only I could cut the noise down on southampton

are you using gears or belts ?

standard cogged box, something like 3.4 to 4-1, pencil eraser sized input 2p coin sized output, plastic cogs, straight cut, sounds like a cat in agony

Just change to toothed belt system

easier said than done, its the southampton RTR, the gearbox is also the engine mounts, all you see of the motors is the contacts for the wires, and the cogs on the outside.

post a picture if you can you may be able to change the internals.
