RTR vehicles in general are just for people who want to make spontaneous purchases, throughout the RC genres, most of the comp level rigs are kits, and most of the entry level rigs are RTR. Axle tageted a niche with the ARTR that a lot of people needed, and I think they will soon be selling a RTR that is crawl capable out of the box. The AX-10 kit was named truck of the year by RC Car Action, and that's HUGE considering a few years ago you couldn't buy crawler parts, you had to make them. I believe Axial has a lot to do with the crawler craze, and I think you're going to see some of the big companies following in Axials footsteps to keep up. I have to say though, the axials have been so good to me, and they do so much for the industry, that I plan to stick by them for a long while.
