Motor: 55T Electric Motor: designed exclusively for RC Rock Crawlers to conquer all terrain in-door or out-doors. Easy operation: no tuning, no fuel, no loud exhaust noise. Just plug'n'go!

• WHY 55T?: The 55T provides optimum low-end pull and slower wheel speed while crawling.
• "X" 27T STANDARD ON THE RTR: Want to go faster! Try swapping out the 55T for a 27T Motor - PT# AX24004

Slipper Clutch: Allows the motor to work more efficiently and greatly enhances the durability of the drivetrain. Also allows the transmission to slip-in hard binds - this helps to prevent the damage of drivetrain components.

• TECH TIP: Adjustable so you can set the amount of slip that works best for you. Allows for varying types of driving styles.

Transmission: Ultra compact and lightweight transmission. This design is meant to keep your center-of-gravity (COG) as low as possible to minimize roll-overs.

• DID YOU KNOW? The Axial transmission is one of the most highly respected and sought after components from our AX10 Scorpion line-up because of it's proven durability and low center-of-gravity (COG).
• Overall gear ratio range from 15:1 to 74:1: Spur gear and pinion gear is changeable. Allows for tuneable wheel speed.

Full Ball Bearings: For precise gear mesh and reduced rolling resistance throughout the drivetrain.

• Rubber shielded bearings helps to keep dirt and grime out which keeps your bearings rolling smoothly.

Designed for Punishment: Durable composite plastic links are designed to absorb and flex under extreme conditions. Flexing helps to take the punishment of repeated falls onto even the rockiest of terrain.

• Plastic links not only withstand the abuse received from unforgiving terrain and hard binds, but they also provide your crawler improved ability to slide over obstacles vs. getting hung-up on them - one of the main reasons why the top chassis skid plates are made of composite plastics.
• New geometry options/tunability.
• OPTION PART: If you're looking to switch to aluminum, you'll need the AX10 Scorpion Color Packs which are available in 4 colors. This kit requires AXA1411 hardware pack.
  

Axles - Proven Durability: The axles have been designed with many features that are not available from other products on the market.  Everything from the axle strength, pinion angle, caster, and ground clearance were taken into consideration when designing these axles. The result is a far superior axle that will stand-up to some severe punishment.

• To ensure added longevity from the start a hardened drive shaft is included.
• OPTION PART: Utilize Optional Ratio Gear Sets in different combinations front and rear to reduce torque twist in the rear and overdrive the front axle to help pull you through climbs easier.
• TECH TIP: Try the lower gear set to reduce torque twist (43/13), and the higher gear set for higher top speed (36/14).
  

Differential Locker: Locked differentials front and rear for "true" 4 wheel drive. 4WD allows all wheels to maximize traction when crawling.

• Fully locked differentials for more traction when rock climbing!
• Locked front and rear (spools)
• Made from strong sintered metal. Sintered metal provides superior metallurgical characteristics and can be manufactured with very tight tolerances.

Tires: Pro-Line® Hammers with Pro-Line® Memory Foams. The Hammers utilize a totally unique compounding process. Super soft yet maintains tread shape and carcass shape while climbing under the most extreme conditions. The tread is designed for forward bite and sidehill capability.

• PRO-LINE® MEMORY FOAMS: has several distinct advantages over standard foam inserts.
• First, it allows the tire to flex more over obstacles. This allows your tire to work more efficiently and effectively. This also helps to maintain a more level chassis by absorbing these obstacle.
• Second, because there’s more tire flex it also provides more tread on the ground giving more contact patch. The more contact patch the greater the traction you’ll have and the easier it will be to clear tough obstacles.
• Lastly, the foam does not bounce back and this promotes a more stable crawler. Standard foams spring back right away where memory foam maintains a compressed shape longer making wheel hop less likely.

Wheels: True beadlocks: The added realism of 1:1 wheels isn't just for looks because beadlocks also require no messy glue, and allow you to re-use your wheels.

• WHEELS: Axial 2.2 8 Hole Beadlocks (satin chrome)
• OPTIONAL PART: Rock Ring and Standard Beadlock rings available in 6 different colors: Green, Red, Grey, Orange, Blue, and Purple
• OPTIONAL PART: 2 different styles: 8 Hole and Rockster wheel. 4 finishes: white, black, satin chrome, and black chrome.

All New Competition 72-103mm Shocks: Threaded shock body for easier pre-load adjustments: Use to adjust ride height, optimize articulation, and reduce torque twist.

• 72-103mm shock length, helps lower the center of gravity.
  
• 3.5mm titanium nitride coated shock shaft reduces lateral movement.
  
• Cartridge style bottom helps reduce lateral movement while providing a better seal for less leakage.
  
• Silicone diaphragm provides more consistent feel and better seal to prevent leakage.
  
• Silicone bushing in cap holds shock in place while allowing freedom of movement to prevent binding and prevents the shock cap from popping off.
• These shocks are "Mmmh mmmh, buttery smooth!"
• OPTION PART: Aluminum competition 72-103mm shock set.
• TECH TIP: If you've decided on the aluminum shocks be sure to check out our tech build on building the shocks. NOTE: RTC shocks come pre-assembled.

Electronics: Electronic Speed Controller (ESC): Hi-quality durable forward and reverse speed controller.

• TECHNIQUE: No reverse delay to prevent rolling over backwards on steep climbs.

Lexan Upper-Link Plate: You can relocate electronics using the plate which helps lower center-of-gravity.

• Lightweight lexan construction with overspray mask so you can leave it clear or paint it to match your truck
• Includes plate and 4 zip ties

XC-1 Rock Crawler Body: Designed from the get-go as a competition level rock crawling body to allow clearance where needed when crawling.

• Tapered front and rear end allows more articulation space – TECH TIP: Trim the fenders for even more clearance. THE RIGHT TOOLS: Lexan body scissors with a curved tip makes cutting lexan bodies extremely easy.
• Side skirt acts as a skid plate when on the rocks and offers increased ground clearance.
• Durable .040” polycarbonate body stands up to abuse from the
  rocks.

ADDITIONAL FEATURES

• Mount a standard stick pack to get up and running quickly, or use the included upper link plate to mount smaller batteries lower in the chassis for improved crawling performance
• 14T pinion paired with an 87T spur gear gives you a decent amount of wheel speed and great low-end torque.
• Hi-quality composite plastic and metals
• Hi-torque metal gear servo helps hold your line when rock crawling
