We're in development of BL controllers for cars at the moment. We've just finished a beta period for our 25A 1/18th version (the Mamba 25), and are finishing up the software for an early Nov. release.
The bigger controller is next (Mamba 80) for 1/12th thru 1/8th cars. no release date yet, but the software will be shared between the two, and hardware changes are easy in comparison.
For right now, you could use the Marine version (programming for pistol grip radios), but there are no brakes :-(
