Losi Rock Rey 1/10th Rock Racer RTR – Unboxing and Compare

The Losi Rock Rey, 1/10th scale Rock Racer is not just another Brushless RTR to hit the market. It captures a specific niche in the radio control market with a dual suspension set up being an independent front and a solid axle rear suspension. Unlike the Baja Rey, the Rock Rey has an open wheeled buggy design based on some of the “King of the Hammer” vehicles that raced just a couple of weeks ago for the annual tough test in the California desert.

Basher and Racer

The Rock Rey really hits both markets:

“The Basher” – The person that just wants to go out and have fun and run this over and over again at their local spot, backyard or even in the street.

“The Racer” – The person that participates in U4RC events, racing this to the extreme. U4RC races have huge jumps, rock gardens and timed races to the death!

Companies like Vanquish Products and others are already jumping at the bit to make upgrade parts to enhance the Rock Rey and give it an even more durable approach on both he bashing and racing scene.

The Unboxing

First glance at the Rock Rey and it’s huge! Yes, 1/10th scale these days just means it runs 1/10th scale electronics and has typically 12mm hexes for the wheels. Scale is not a reality anymore when comparing a vehicle to an RC.



The tires are massive – the licensed Maxxis “Creepy Crawer LT” tires are one of the largest 2.2” (wheel size) tires I have seen. The tread and compound (how grippy the rubber is) is pretty decent for an RTR.


Supplement Items

The supplement items in the box are minimal but just enough, including:

  • Spektrum branded DX2e 2.4ghz AVC capable radio
  • Four AA batteries for the radio
  • Light bar cover
  • Chrome accented light buckets for the headlights
  • Owners manual
  • Bind plug for the receiver


The Rock Rey is based off an independent front suspension and a solid axle rear (like most of today’s pick up trucks) This offers a realistic scale experience when driving it. All power is managed by an open front and center differential and a locked rear differential. The 3mm 6061 aluminum chassis plate offers additional durability and no flex.



The electronics really set the Rock Rey apart from the competition with a 2s-3s capable brushless sensorless system including. I could not find any specs on the servo other than it being metal geared and waterproof:

  • Dynamite FUSE 550 sized 2800kv brushless sensorless motor
  • Dynamite FUSE 130amp brushless sensorless electronic speed control
  • Spektrum DX2e AVC equipped radio system with the SRS4220 receiver

Scale Features

Scale features on the Rock Rey have exceeded my expectations adding both functional and non-functional items to add to that scale realism:

  • 6” fully functional super bright LED light bar
  • Driver and navigator figure interior
  • Radiator fans

What You Need to Get It Running

What’s needed to complete the package and get your Rock Rey running?

A good 2s or 3s Lipo battery with an EC3 connector and a Lipo Balancing charger. I recommend these options:

Reaction 3s Lipo Battery: amzn.to/2mXLbBr
Reaction 2s Lipo Battery: amzn.to/2mY4r1V
Prophet Lipo Charger: amzn.to/2mkfA9A


Overall the Losi Rock Rey looks to be a great option for almost any RC enthusiast. It offers scale realism, brushless power, solid suspension and overall durability. Is the Rock Rey in your future? Is there a better RC on the market? What RC is your favorite RC of 2017?
