Finally come up with a proper design for HardWired Evolution mkII (cunningly named HardWired Revolution) - basically, think Tornado style 4WD box, but with a wedge on the front and a heavy vertical spinning blade in the middle of the wedge. The way I'm going to try and build it is so that it's a rambot with the power and speed of, say, Satanix or 540, but the heavy disc's for getting the launches that 720's pulled off in the last champs (that one against one of the Toon robots most notably!)
Maybe it won't fully work out as planned, but the idea is that I'd essentially have the best of both worlds of a drum spinner and a rambot.

This was the idea I had for my 'proper' beetleweight but it seems like it'd be a pretty solid featherweight in all honesty. Might make a beetle and upscale once I've refined it a tad and don't have the building abilites of a chimpanzee wearing thick woolen mittens.
