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, acceleration 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.

RC GUY GARAGE here.
The Arrma Big Rock has just become my favorite 1/10 scale 3s ripper. I have taken it to a place known as Diamond Dust and this thing ran with the 1/5th scales and took the Beatdown like Total champ.

Arrma Big Rock 4X4 V3 3S BLX 1/10 RTR Brushless Monster Truck (Black)
Excellent, except for the plain black color the body is slightly thicker than the Senton I had previously and feels tougher. The brushless motor esc is good except for a slight lag when changing direction or starting from a complete stop, probably need to do an adjustment . Only running two cell but fast. Very durable have had it tumbling quite a bit and doing cart wheels nothing broke, very durable. I like the wide wheel base, great truck highly recommended.

Arrma Big Rock 4X4 V3 3S BLX 1/10 RTR Brushless Monster Truck (Black)
I’ve just recently got back into RC cars again after a decade. I used to run nitro/gas RC vehicles and I was a Traxxas geek ?. A friend of mine showed me his line of ARRMA RC’s and I was so impressed after testing them out.

I never owned an electric RC and it was so much fun I purchased the Big Rock. The Big Rock is fun to bash with on any surface out of the box. It is fast and durable. I have no major negatives about it with only one minor incident. The right rear rolled away during run time. I thought it was hilarious but an easy fix. Just had to tighten it with blue loctite.

Happy with my purchase!

Arrma Big Rock 4X4 V3 3S BLX 1/10 RTR Brushless Monster Truck (Black)
Awesome!!! This is my first RC and it has been worth every penny. After the third run, I broke the composite RF Steering Box, bent the LF shock shaft, and bent the RR turnbuckle. I learned the hard way that non-oe parts are harder to come by as this is the V3 Crew Cab, not the 4x4 crew can that many parts are available for.

I replaced A-arms with the RPM 4x4 arms (RPM81502, and RPM81492), which shortened the wheel base, but also allowed for the Lunsford titanium turnbuckles to fit (pn-LS40012). These parts are will not maintain the stock V3 Big Rock Crew Cab Wheel Base. The shock mount locations are different which made for a hell of a time installing the HR Shock Bodies with Progressive Springs. On the shock bodies I had to install nylon spacers purchased form my local hobby store to as the eyelet to eyelet distances are different between arrma and the HR shocks, plus the mount locations on the RPM A-Arms is different. I also installed an aluminum C-Hub and Steering Box (from HobbyPark) which required shimming with arrma tie rods / turnbuckles, but not with the HR Pivot Ball set ATF160B02). The HR pivot balls do not fit on the HR shock bodies, but fit nicely on the stock rods.

The truck has been on 30+ runs already, this thing is a beast and takes a beating. I'll be putting the GPM A-Arms, and tie-rods on to restore the stock wheel base. Adding Proline Badlands 2.8 Raid tires requires the HR 17mm Hex Hubs (ATF117XT02) and the Proline 6x30 17mm hex hub adapters (PRO6336-00) which I have ordered and will be installing.

Very happy with purchase. Required repairs have been minimal and the upgrades are fun, but do cost!

Pretty thrilled with this arrma. I have mostly crawlers 1/10 scale.
Impressed with handling, speed, agility.
Build fit and finish superb. Great truck at any price.
Love the dual cab truck.
A-Main keeps my business because they have proved to have great customer service. I've had questions, they had patience to answer.
Web site, especially orders, easy to navigate.
Shipping us very fast. They keep me informed immediately is stock ran out.
It's what's important to me and a company is that they keep me informed if I'm spending my money with them on orders. Amainhobbies does this and does it very well. So I will continue to shop with them and spend my money with this company. Thank you A Main Hobbies for being there and being professional

Arrma Big Rock 4X4 V3 3S BLX 1/10 RTR Brushless Monster Truck (Black)
This truck is pretty solid and offers great performance out of the box. Only reason I had to ding it 2 stars is because of a consistent flaw in all these Arrma 3S vehicles --- the motor mount and slipper clutch design. If you jump these vehicles regularly, you'll eventually notice that the stock motor mount bends enough to throw off the gear mesh and chew up the spur gear. You'll find plenty of owners who have documented these issues, so it's not just my experience.

There are some aftermarket motor mounts which purport to fix this issue. I have tried many of them, but have yet to find a permanent mitigation.

Otherwise, these rigs are built very tough and lightweight, which helps with affordability and durability. I still bash mine hard even though I have to replace the spur gear every now and again.

Great 3s truck, lots of speed.The rear arms get a little loose, definitely getting RPM arms soon. First ARRMA I've gotten and I like how easy it is to take a part for repairs or swapping the hardware with stainless hardware.

This truck is awesome! I’ve been running it hard for a few weeks now and it’s so much fun. It’s faster than I was expecting, overall solid choice. Only damage so far is a bent shock shaft but I sent it off a big jump and landed terribly. No regrets!

Fun, fast, and tough. Bought this because a friend's kids got interested in my RC collection and the amount of power can be adjusted buy the transmitter. It prefect for young kids to learn how to drive and control an RC.
