Heavy-Duty Drivetrain

High performance must come with high durability. Traxxas delivers with a robust shaft-driven AWD (all-wheel drive) system proven in our most powerful vehicles and enhanced with new features for XO-1. Steel-gear, E-Revo-spec differentials feature reinforcing support bars to increase horsepower handling capability. The extruded aluminum center driveshaft engages the front and rear gearboxes directly, so there are no dogbones or drive cups to wobble or wear. New, telescoping steel-spline (SS) driveshafts with dual CV joints engage the wheels with track-tested, splined 17mm hex hubs. New fine pitch splined steel telescoping driveshafts handle 50% more torque than conventional shafts. Oversized 6X12mm ball bearings spin efficiently at high rpm, run after blistering run.

Real-Time Telemetry

Traxxas Link collects and records real-time telemetry data as you drive. The Traxxas Link dashboard comes to life showing you speed, battery voltage, RPM, and temperature. The application automatically detects and recognizes Traxxas Link sensors for easy set up and configuration. The dashboard is fully customizable with either dial or digital readout gauges. Up to nine gauges can be displayed at once. Set threshold warnings and log maximums, minimums, or averages. Use the recording function to document your dashboard view, with sound, so that you can keep your eyes on your driving and not miss a single apex. If you forget to record, simply touch Instant Replay anytime to capture the previous minute of fun and unexpected triumphs. The recordings can be named, saved, and shared with others.

Computer Optimized Aerodynamics

Developed with advanced modeling techniques, XO-1's stunning form has been shaped by pure function. The front splitter and canards, smooth undertray, rear diffuser and wing work in harmony to harness airflow and convert it to downforce while minimizing drag—critical to achieving 100+mph speeds. XO-1 is the first to deploy a fully developed and functional air-management system in a high-performance radio-control car. The aerodynamic components integrate seamlessly with the XO-1's low-slung, wide-stance body to distill style and speed into a pure expression of radio-control performance.

Ready-To-Race with Included Power Cell LiPos

"100+mph, right out of the box." That was the goal for XO-1, and Traxxas delivers with everything you need to hit triple digits—including a pair of Power Cell 3S LiPo batteries. Built with custom Traxxas cells and engineered specifically for the high power demands of Traxxas vehicles, Power Cell LiPo packs are fully equipped with Traxxas High Current connectors, Maxx Cable 12-gauge wire, and standard JST/XH balance plugs for long cycle life, maximum run time, and track-shredding punch.

Traxxas Big Block Brushless Motor

The ultimate brushless powerhouse! Custom tuned for the XO-1, the Traxxas Big Block motor features a finned, heat-dissipating can, oversized premium-quality bearings, sintered Neodymium magnets, and superior electromagnetic design. The Big Block brushless motor invites "cubic inches" to the party for massive acceleration and true supercar performance with the largest brushless motor ever offered in a Ready-To-Race model.

 Patent-Pending Cush Drive

Developed specifically for the XO-1, the patent pending Cush Drive™ absorbs drivetrain shocks with a custom-shaped elastomer damper housed between the spur gear and the drive hub. Under extreme load (such as hard, high-traction acceleration), the elastomer flexes to dissipate shock without interrupting power flow. The result is instant acceleration with no wasted power.

Extruded Aluminum Driveshaft

XO-1's center driveshaft is formed from extruded aluminum. There are no dogbones to wear, no drive cups to wobble. The extrusion process allows the shaft to be hollow and lightweight with internal splines that fit directly and securely onto the input shafts of the front and rear drive assemblies. The shaft runs perfectly straight and true and offers superior durability. Traxxas engineers highlighted this important innovation with vivid blue anodizing and a laser-etched Traxxas logo.

Impressive 1/7 Scale Size

At a full 27 inches long and 12 inches wide, XO-1 is a commanding presence on the road. Its extra-large 'footprint' improves stability, increases traction, tolerates road imperfections, and delivers high-speed handling that no 1/10 'touring car' can match.

Revo-Spec Differentials

Race-proven in the 8-time National Champion Revo, XO-1's differentials represent the state of the art in power handling and efficiency. Precision silicone gaskets and X-ring seals allow the diffs to be tuned for specific running conditions by varying the viscosity of the fluid inside them. Reinforcing bars within the differentials increase strength to withstand XO-1's over-the-top power. Differential access for tuning is quick and easy. Just remove the front or rear cover and the entire differential slides right out.

Computer Optimized Aerodynamics

Developed with advanced modeling techniques, XO-1's stunning form has been shaped by pure function. The front splitter and canards, smooth undertray, rear diffuser and wing work in harmony to harness airflow and convert it to downforce while minimizing drag—critical to achieving 100+mph speeds. XO-1 is the first to deploy a fully developed and functional air-management system in a high-performance radio-control car.

Aggressive Supercar Styling

XO-1's advanced aerodynamic components are integrated into a unique body developed specifically for high-speed stability and increased downforce, with a powerful, wide-track look. The body is molded in durable 1mm polycarbonate and features a metallic finish available in four colors. The durable, injection-molded rear wing is mounted solidly to transfer downforce to the body and chassis.

Standard and High Downforce Splitters

XO-1 combines extreme high performance with sport driving versatility by including two splitters: the factory-installed standard splitter, and the canard-equipped High-Downforce splitter for 100+mph speed runs. The aggressive canards provide very high downforce to keep XO-1 locked to the pavement. The splitters are constructed of flexible plastic to resist impact damage, and the splitters and canards can be replaced individually in minutes.

Steel-Spline Dual CV Driveshafts

Developed specifically for XO-1, the new SS (steel spline) dual-CV driveshafts are stunning examples of high-strength, low-mass construction and Traxxas' attention to detail. The splined, nickel-plated shafts slide smoothly as the suspension is compressed, assuring efficient power transfer. The female half-shafts are machined and hardened steel with a durable black-oxide finish. The telescoping shafts handle much greater torque loads than conventional driveshafts. Flexible rubber boots protect the CV joints and splines from dirt and debris.

Heavy-Duty 17mm Hex Hubs

Proven tough by the Brushless Edition E-Maxx, E-Revo, and Summit, Traxxas' splined 17mm aluminum hex hubs are standard equipment on the XO-1 to make certain its considerable horsepower is transmitted directly to the road. The splined design is extra strong with unsurpassed torque handling to resist twist-out no matter how hard you launch the XO-1 off the line.

Scalable Battery Compartments

XO-1 can accommodate a variety of battery configurations and sizes with its unique, scalable battery compartments and quick-release hold-downs. The compartments' rear bulkhead can be positioned for 135mm and 155mm pack lengths. The hold-downs can be flipped to hold 23mm and 25mm pack heights. With the optional expansion clips, 38mm to 43mm tall packs can be installed. Removing and installing batteries is easy; just flex the latch open to release the pack, and snap the hold down into the latch to lock it into place.

Hard-anodized, Teflon-Coated GTR Shocks

State of the art in every way, XO-1's hard-anodized, Teflon®-coated aluminum GTR shocks represent the pinnacle of performance, offering silky smooth damping and a serious factory-works look. Thanks to the extra tough hard-anodized finish, shock performance stays true and consistent for less maintenance and better handling, run after run. Titanium Nitride coated shock shafts slide past X-ring seals for virtually friction-free operation, incredibly responsive suspension action, and extra-long seal life. The durable titanium nitride finish offers durable, smooth, consistent performance.

Speed-Rated Belted Tires

Specially developed for high-speed use, XO-1's slick tires are the first to be rated for 100+mph. Zero-stretch belting reinforces the soft-compound rubber, and molded inserts support the tread. Black-chrome Split-Spoke wheels set off the 17mm blue-anodized nuts that secure them, and the wheels extra-wide tire mounting area assures 100mph reliability.

 Heavy Duty Module 1 Gears

'Pitch' refers to a gear's tooth size—the smaller the number, the bigger the tooth. Electric cars typically use 48 pitch gears; 32 pitch is common for nitro. XO-1's gear teeth are the largest in the Traxxas line: Module 1, the equivalent of 25.4 pitch. In addition to having larger, more durable teeth, XO-1's gears are a full 8mm wide to spread drive loads over a greater area to extend wear and increase efficiency. Even the pinion is specialized, made of high-strength steel and developed specifically for the XO-1.

3mm Aluminum Chassis

XO-1 relies on the proven strength of aluminum plate construction for its chassis. The 3mm 6061 aluminum upper and lower decks are rigid yet lightweight, and the lower plate acts as a heatsink for the power system. The aerodynamic components are fully integrated with the chassis in a combination of art and science that could only come from Traxxas.

Machined Aluminum Motor Mount

For maximum strength and enhanced motor cooling, XO-1 features a new machined-aluminum motor-mounting system. The 8mm thick aluminum resists flex and holds the motor tight under the highest loads. XO-1's high rpm and torque make proper gear mesh critical, so Traxxas engineers incorporated a unique adjustment screw into the mount to dial in the gear mesh with micro-precision.

Machined Aluminum Shock Towers

XO-1 is factory equipped with machined aluminum shock towers to provide stiffness and strength fox maximum control. The rigid shock towers make sure the XO-1's GTR shocks work efficiently to absorb road imperfections and cornering loads. Vivid blue anodizing highlights the towers against XO-1's dark-anodized chassis and black parts.

High Strength Machined Aluminum C-Hubs

XO-1's artfully machined aluminum C-hubs are Traxxas Tough and feature carefully engineered steering and suspension geometry for track-ready performance. The brilliant-blue anodized finish, machined highlights, and the laser-etched TRX logos show off Traxxas' signature style.

Aluminum Steering Blocks

Precision-machined for total steering accuracy and bulletproof strength, Traxxas Aluminum Steering Blocks deliver razor-sharp handling and precise control at triple-digit speeds. Solid 6061 aluminum construction guarantees road-ready strength and stiffness. The blocks hold heavy-duty 6X12mm bearings selected just for XO-1.

Machined Aluminum Rear Hub Carriers

New Traxxas aluminum stub axle carriers add larger 6x12mm bearings to handle the high-rpm demand of a 100+mph supercar while maintaining the beautiful blue-anodized look of the machined axle carrier.
