Technical Performance
The ARRMA INFRACTION 3S 4X4 BLX represents the pinnacle of all-road RC truck engineering, combining cutting-edge components with proven platform architecture. At the core sits the powerful Spektrum Firma 3660-size 3900Kv brushless motor, a non-sensored unit that delivers 65+ mph capability when paired with the included optional speed pinion gear and a 3S LiPo battery in optimum conditions. The motor is controlled by the Spektrum Firma 100A Smart ESC, a sophisticated electronic speed controller featuring IC5 connectors for clean power delivery and future expandability. This ESC is pre-programmed with Smart technology integration, enabling real-time telemetry streaming and advanced vehicle data logging through the optional Spektrum Dashboard mobile application when paired with the BT2000 Bluetooth Module.
The drivetrain architecture features a proven 4WD system with a final drive ratio of 7.12, internal gear ratio of 2.85, and a 50T spur gear paired with a 20T pinion (with optional 20T speed pinion included for maximum velocity). The metal-geared differentials throughout provide smooth, reliable power distribution to all four wheels, with castellated slipper pad and sliding gear mesh refinements for controlled slip and protection. The transmission is brushless-ready and optimised for high-performance operation. The truck measures 562mm in length, 257mm in width, and 161mm in height, with a total weight of 2.85kg, creating a purposeful stance and excellent inertial characteristics for high-speed running. Ground clearance stands at 15mm, the wheelbase extends 335mm, whilst the front and rear tracks measure 255mm and 256mm respectively, providing a stable, planted driving platform.
Suspension geometry includes independent double-wishbone design front and rear with front and rear sway bars for ultimate all-road handling. The oil-filled coil-over shock absorbers feature threaded bodies for easy ride height adjustment and silicone O-rings for reliability. The battery tray accommodates 2S or 3S LiPo batteries with maximum dimensions of 165x51x48mm and minimum specifications of 5000mAh 50C capacity. The truck features a robust composite moulded chassis with extended height dirt defenders, steering geometry with stone clearance, and rubber-shielded bearings throughout all rotating components. The radio system comprises the Spektrum 2.4GHz DX3 Smart DSMR transmitter with three channels, operating on the secure, globally recognised frequency with DSMR technology for interference-free control. The factory-installed Spektrum SR6200A receiver integrates Active Vehicle Control (AVC) on-demand traction control, allowing real-time stability adjustment during driving. The 14mm wheel hex size accommodates the included dBoots Hoons Elevens vented all-road tyres mounted on tough gunmetal nylon wheels, delivering exceptional traction and sidewall support during aggressive acceleration and cornering. All critical components are finished to professional standards, with authentic resto-mod body styling available in two striking matte and gloss effect colour schemes that command attention whether parked or in motion.

Frequently Asked Questions
- Is the ARRMA INFRACTION 4X4 3S BLX suitable for intermediate drivers? — Yes, ARRMA specifically recommends this truck for intermediate-level drivers. The truck is ready to run out of the box with factory-installed Spektrum electronics including the SR6200A receiver with AVC on-demand traction control, which helps newer drivers maintain stability. The AVC system can be dialled in or out as you gain experience, making it forgiving for learners whilst providing the performance depth experienced drivers demand.
- What top speed should I expect from this brushless RC truck? — The truck is capable of 65+ mph in optimum conditions when equipped with the included optional speed pinion gear and a 3S LiPo battery. Actual speeds will vary based on battery condition, terrain surface smoothness, vehicle setup, and environmental factors such as air temperature and humidity. On rougher terrain or with a 2S battery, speeds will be notably lower but the truck remains very quick.
- What battery does the INFRACTION 3S 4X4 BLX need? — This truck is compatible with both 2S (7.4V) and 3S (11.1V) LiPo batteries with a minimum capacity of 5000mAh and 50C discharge rate. Battery dimensions must not exceed 165x51x48mm to fit the battery tray. For maximum performance and the advertised 65+ mph capability, a 3S battery is recommended. If you're using a 2S battery, expect lower speeds but still impressive performance around 50+ mph.
- Does this come with a battery and charger? — No, the battery and charger are sold separately. The truck comes fully assembled and ready to run with transmitter, receiver, motor, and ESC pre-installed, but you'll need to purchase a suitable LiPo battery (2S or 3S), a dedicated LiPo charger, and four AA batteries for the transmitter to start running.
- What is the difference between the INFRACTION and the VENDETTA? — The INFRACTION 3S 4X4 BLX combines the high-speed performance capability of the VENDETTA platform with the distinctive resto-mod styling of the INFRACTION design. Both trucks share the same proven 4WD platform and Spektrum electronics, but the INFRACTION features the iconic retro truck body styling available in two striking matte and gloss effect paint schemes, whereas the VENDETTA focuses on contemporary performance aesthetics. The INFRACTION is positioned as an all-road truck suitable for both on-road and light off-road use.
- Can I run this truck on grass and dirt? — Yes, the 4WD drivetrain, independent suspension, and dBoots Hoons Elevens vented all-road tyres make the INFRACTION equally capable on grass, dirt, loose gravel, and light off-road terrain as well as on-road surfaces. The AVC traction control system is particularly useful on loose surfaces, providing stability and control without requiring throttle modulation.
- Is the INFRACTION 3S 4X4 BLX waterproof? — The truck is water-resistant rather than fully waterproof. The Spektrum Firma ESC and S651 servo are waterproof-rated, allowing occasional light water exposure, but the truck should not be submerged or intentionally driven through deep water or flooded terrain. Light rain, damp grass, and puddles are acceptable. Always dry the truck thoroughly after wet running and check all components before recharging batteries.
- What's included with the AVC traction control system? — The Spektrum SR6200A receiver with AVC is pre-installed and ready to use straight from the box. AVC provides on-demand traction control adjustable via transmitter trim controls, making hundreds of automatic steering and throttle adjustments per second to maintain your desired line through loose surfaces and challenging terrain. You can dial AVC stability assistance up or down or turn it off entirely, giving you complete control over the level of assistance.
- Can I integrate this with the Spektrum Dashboard app? — Yes, by purchasing the optional Spektrum BT2000 Bluetooth Module separately and downloading the free Spektrum Dashboard app for iOS or Android, you can monitor real-time telemetry including top speed, battery voltage, and other essential data. The Smart ESC logs this information, allowing you to review performance data after each run.
- What maintenance does the INFRACTION require? — ARRMA's modular design makes maintenance straightforward. The power module (motor and ESC) removes easily, the differentials are accessible without complete disassembly, and rubber-shielded bearings throughout protect against dirt ingress. After each run, inspect tyres for debris, check battery voltage, and clean the chassis of large dirt accumulation. Periodically check all fasteners and bearing conditions. See the included multilingual manual for detailed maintenance guidance.
- Does this truck come with spare parts? — The truck includes a comprehensive exploded view diagram and shoppable parts list. Replacement and optional parts are widely available from authorised ARRMA dealers including RC Model Shop, covering tyres, body components, suspension parts, electronics, and drivetrain components. The included optional speed pinion gear is your first upgrade opportunity for maximum velocity.
- What is the warranty on this truck? — ARRMA provides a 2-year limited warranty covering manufacturing defects. See the website support section or documentation included with your truck for complete warranty details, coverage scope, and claim procedures. This warranty does not cover damage from crashes, misuse, or normal wear and tear.
