I bought an rc rat to torture the cats with. Runs on lipo and there's no screws, so no maintenance. It's quicker then my Raminator. Best $20 I've spent in a while. Seriously, maintenance is as big a part of the hobby as driving. If you want less maintenance, put a new titian back in that rusty, set the mesh right so you don't smoke it and run the stock gearing with no more then a 3000 pack. More performance equals more maintenance.
