Your Guide To The ARRMA Big Rock 3S

ARRMA brought back the popular "street truck" style of the earlier 1/8 scale BIG ROCK with the BIG ROCK CREW CAB 4X4 3S BLX in a way you've never seen before.  This 1/10 scale monster truck runs on the powerful new 44 BLX platform.  It's a highly durable monster truck perfect for your wildest adventures.  It's an ARRMA tough RX that can hit speeds of over 50 mph!

The truck's long, scale crew cab body is accented by black chrome-plated front and rear bumpers and wheels, and it's the epitome of street style. You'll be able to run it over dirt tracks, trails, and even muddy courses with the included Boots RAGNAROK MT tires. A wheelie bar with adjustable height comes standard, allowing you to have some stunt fun on your epic adventures.

The Big Rock 3S  was designed to have the muscle and durability to take on any challenge. Its transmission and chassis designs, which have already proven themselves on the GRANITE and SENTON 44 3S BLX RTRs, provide the durability you'll need to get the most out of the BLX100 brushless power system. The BIG ROCK CREW CAB 4X4 3S BLX unleashes an avalanche of speed when the 3200Kv brushless motor and 100A ESC work.

You can start your adventures as soon as you get your ARRMA Big Rock 3S because it comes ready to run. You just need batteries, chargers, and “AA” transmitter batteries.
