JohnRobinsonRC Single motor RTR with a dual motor mount included at release would he the best option for sure. I doubt they'll include it with the kit though, but can see it being a purchasable optional part. I really dont think they should release a roller first, for many reasons. Probably about 75% of rlaarlo fans/customers an rc fans in general aren't that intuitive when it comes to rc's. They'd most likely want a car they can buy an run, an maybe upgrade later. Not have to purchase a roller, then choose a motor/esc/servo/etc. Of course expert's don't mind a roller but the overall rc community from novice to expert would benefit the most from a RTR and will bring in more sales. Also releasing a roller first will really be in competition with the limitless.
