I've done some minor conversions but this is gonna be my first attempt at a scratch build, i want to make a war wagon based off of one of the two legged red tanks from an upcoming sci-fi sequel(could i say the name?) but longer. generally a tank but where the treads should be will be two hover long hover columns. Any and all advice would be very welcome. Model kits that might make a good base, an easy way to build a frame to work from, a way to make the engine's / feet, most anything. My local hobby store has a lot of bits box's with a abundance of old style rhino body's to use for armor plating.
