I've been following them in the Rum Runner Racing forum and was the first to ask about a car version. Here is the link:
http://www.rumrunnerracing.com/fefor...ad.php?t=31671 and I asked in post #16. They mentioned that the ESCs aren't made by Suppo, but all the programming sure looks like it is specially the car one since I was trying to get Suppo to make my HV car ESC a while back. If they can make the shorter version, that would be a plus.
