I'm thinking... RC 1/76 model bus?

[Bruce_LOA400X]

I want to make one...

I don't know if to try it with a corgi 1/64 RM first and use a cheapy 1/64 RC car off ebay, use the mechanism from one of those (will involve hacking loads) and seeing how it works. alternatively I may try building my own chassis. at the very least all i need is backwards forwards and left and right. If I want to expand I could always put lights on it later on...

I'm mental aren't i?
