The Arrma Big Rock 4X4 V3 3S BLX 1/10 RTR Brushless Monster Truck delivers a thrilling combination of ARRMA toughness, street truck style and 50+ mph speed capability. Built on the powerful 4X4 BLX platform, its precision aluminum, tough steel and composite materials come together for an easy-to-maintain, super-durable vehicle design that’s now been upgraded to further increase the monster truck’s impressive performance and durability.

Built for exciting bashing speeds and extreme, all-terrain durability, the Big Rock 4x4 V3 includes features that enhance its unstoppable performance. A stronger chassis and retained hinge pin plates; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; longer suspension arms for a 1.10 inch increase in width; and rubber-shielded bearings throughout are now included to take your bashing session to the next level.

It also now includes a Spektrum SLT3 transmitter and SLR300 receiver. The transmitter is ergonomically designed for long periods of fatigue-free bashing and has a foam wheel for precise fingertip control, plus an improved hand grip and trigger feel. New bashers will be able to set throttle limits at 50% or 75% until they are ready to use the full speed potential. The SLT3 is compatible with Tactic SLT receivers to run other RTR vehicles you may own, and includes a third channel to control optional features such as lights and winches on models that have them.

ARRMA now powers the BIG ROCK 4X4 3S BLX with a brushless system featuring its BLX100 ESC and the Spektrum Firma 3200Kv brushless motor. The combination provides incredible torque and speed. The transmission and chassis are ruggedly engineered to take full advantage of the power.

Its full-time 4WD transmission uses strong front, rear, and centerline telescopic driveshafts that can’t be lost during heavy impacts, unlike dogbones. A simple, dependable, responsive steering assembly complements the ultra-reliable drive system and features a servo horn with built-in servo saver. The BIG ROCK 4X4 3S BLX RTR includes the waterproof Spektrum SPMS651 metal-geared digital servo for 15% more torque than the previous ADS-7M servo.
