Axial Racing AX10 1/10 Ready-to-Crawl Scorpion with 2.4GHz Radio 55T Electric Motor: designed exclusively for RC Rock Crawlers to conquer all terrain in-door or out-doors. Easy operation: no tuning, no fuel, no loud exhaust noise. Just plug'n'go! Transmission: Ultra compact and lightweight transmission. This design is meant to keep your center-of-gravity (COG) as low as possible to minimize roll-overs.

Designed for Punishment: Durable composite plastic links are designed to absorb and flex under extreme conditions. Flexing helps to take the punishment of repeated falls onto even the rockiest of terrain.
