The big name in crawlers is Axial Racing. Axial, known to RC fanatics worldwide for its range of replacement nitro engines, has been turning out competition-level crawlers for a while now. Kits and full competition models bred the need for a "ready to crawl" version, something you can take out of the box, install batteries into, and start crawling with. Axial has done just that with the AX10 RTC. Featuring a crawler-spec electric motor, transmission, and gears, the AX10 RTC also has super-sticky crawler tires, front and rear lockers, and true beadlock wheels.
