The 1/10th 2.2 Rock Rey Rock Racer is incredibly versatile. Not only can it take on rocks with ease, this monster can bash over pretty much anything, anywhere. Through mud and water—at staggering speeds over 40 MPH. It features AVC technology, too.


In-Depth Features: 

Realistic 4WD Chassis with Long-Travel Suspension: The Rock Rey chassis is a brilliant blend of scale realism with functional 4WD capabilities. The foundation consists of a 3.5mm, hard-anodized aluminum chassis plate that is integrated with a realistic roll cage made of super-tough composite material. To this it adds a long-travel, independent front suspension and 4-link live rear axle that look and function exactly like their full-scale counterparts.
  • LED Light Bar: Twelve brilliant LEDs on the light bar cast more than enough light for running at night without placing a huge current demand on the battery.
  • Dynamite® 2800Kv Brushless Power System: The vehicle comes equipped with a Dynamite Fuze™ 2800Kv brushless motor and a waterproof 130A ESC. This potent combination can handle 2S or 3S LiPo batteries (sold separately) and will allow you to hurtle across the landscape at speeds of up to 40+ mph.
  • Sealed, Heavy Duty Metal-Gear Transmission and Diffs: The transmission, as well as the front and center diffs, are sealed against the elements and engineered to handle the abuse of a high-output brushless motor and punishing terrain. MOD 1 gears further increase the durability of this off-road beast.
  • Coil-Over Oil-Filled Shocks: The long-travel shocks do a fantastic job of soaking up the energy from big bumps and jumps. They also feature threaded shock bodies with adjustment collars so you can fine tune the pre-load settings of the coil-over springs. External bump stops on the rear provide plush landings on the hardest surfaces.
  • Waterproof Electronics: The receiver, servo and ESC are all waterproof so you can run anytime, rain or shine.
  • Easy-Access Motor: The motor can quickly be accessed for gear changes and servicing simply by removing three screws in the bottom of the chassis.
  • Easy-Access Battery Compartment: A convenient battery door in the back of the chassis makes it easy to swap batteries without having to remove the body or wrestle with battery straps.
  • Bolt-On Body Panels and Detailed Interior: The bolt-on body panels are incredibly durable and eliminate the need for body posts that might spoil the scale looks. You also get a molded interior that includes a driver and rider figure, both of which sport racing helmet and harness details.
  • The Full-Throttle Freedom of AVC® Technology: When you’re ready to let the brushless motor off the chain, don’t hold back. The receiver’s built-in AVC (Active Vehicle Control®) system will work behind the scenes, making hundreds of tiny throttle and steering adjustments per second, so more of the motor’s power is translated into ballistic speed and acceleration instead of just flying dirt. An AVC adjustment knob on the included DX2E transmitter lets you adjust how much traction control the system provides. You can even turn it off.

I absolutely love The Losi Rock Rey. It handles amazing, handles jumps fantastic. The steering and brakes are great. Honestly it is a true hobbyists’ dream RC. I am not sure, but this RC almost makes me want to do a deep dive on Losi who are put out by Horizon Hobby. Really cool. So fast, so controlled, so much FUN. Again I love the Losi Rock Rey.

First time real rc operator other than tycoo fasttrax and tycoo heads up in the eraly n mid 90s bought a 3s5000mah battery and cheap balance charger without discharge option I couldn’t find a solid answer on the web so i used my fluke meter and know tuat i been killing the battery and leaving the car on and it dalls within the tolerances they recommend and seems to have worked woll on over 20 hard runs. I rip a yz250 2 stroke and about always have 13 and im 35 now. I take it to local kids bmx hangout in the woods and impress young leon trotskys like teens in the woods. I control it with confidence n jump it HIGH N FAR. Just broke left tie rod n replaced it with stock part on ebay for 8$. Stock seems good enough for me and cheap direct swap. C how long ot jolds ip otherwise. No spellcheck dont care love the car guys at hobbytown and Amain hobbies were grewt with lots of annoying emails. And prompt
