I've been working on a cart for my sons 4th birthday. Wifey wasn't real inthused but I think instead of battery power they need gas power. batteries last an hour at most and take all day to charge, gas cart just needs to refuel. For this cart i took an old flat chassis and completely reconfigured it. I changed it from a 2 seater to a single seat in the center and bent and welded full roll cage that looks like a sprint car chassis now. I'm actually thinking about putting a body on it now since i do sheet metal work for a living. i will try to post some pics of the progress. Any ideas would be great.
