The only reason not to run that rx in any car would be range related. It doesn't know what scale car it's in, in fact, those were initially marketed to small scale flyers and car people started buying them in droves.

You already bought it right? Do a slow range test and if your track isn't too big, you'll be good to go. If it failsafes on a signal loss, they're easy enough to sell/trade for a different rx.
