Do you mean something along the lines of the
HPI Baja 1/5? If so, I now envy you greatly. I've seen these run around my local flying field by some of the members that are also into land, and I must say, they're both **** quick and fairly agile for such a large RC.
Plus, running off gasoline is a plus with Nitro going for approximatly $20 a gallon (at least around here).
Once you get some, you must post pictures/review and possible video.
Cheers,
Kyle.
