Hahaha, I'll be transporting my MW (and a planned HW) in a 2001 Smart City-Coupe CDI. A Volvo 240 is positivietly cavernous in comparsion so no issues there.

ESCs... Given the overall size I think these are, try looking at Triforces ESCs here (I'll see if I can find the thread later). The full body flipper idea doesn't sound bad to me. The slack might become an issue if not kept an eye on between fights but I can't immediately think of why that wouldn't work.
