Its wide stance contributes to confidence-boosting control at any speed, whether you're racing in your back garden or at your local park. The low and sporty stadium truck body style lets you carve through turns without slowing down, whilst the specialised tread design of the all-new dBoots Dirtrunner ST front tyres makes it easy to jump and corner on rough surfaces. If you're brand new to RC, the included Spektrum SLT2 2-channel radio helps you safely learn control skills by limiting maximum speed to 50% or 75% until you're ready to unleash full power. This is a genuine ready-to-run RC truck that needs nothing else before you can start driving — everything is included, assembled and ready to go.

The ARRMA VORTEKS 2WD is easy to upgrade with LiPo batteries and brushless motors whenever you're ready to take your driving to the next level. The VORTEKS chassis has enormous potential to grow into a next-level RC bashing beast, and the range of optional parts already available means you're never limited by your initial investment. Proven ARRMA engineering gives this vehicle the durability to handle punishing surfaces, making it an investment that will serve you well as your hobby progresses.

Key Features

• Completely Ready-to-Run — Everything you need is included in the box: truck, battery, charger, transmitter and all electronics. There are absolutely no other purchases required before you can start driving, which means you can open the box and hit the ground running within hours.
• Heavy-Duty Brushless-Ready Transmission — The transmission is built tough with a metal gear differential and is designed to handle brushless motor upgrades when you're ready. This means your initial investment is future-proof, and you won't need to replace the drivetrain when you upgrade to more powerful brushless power.
• Easy-Access Bottom-Loading Battery Tray — Changing batteries is quick and simple. Push on the latches, open the door, and slot in a fresh pack without removing the body or fussing with clips. This design keeps you driving longer and means less downtime between battery swaps.
• Hidden Body Retention System — The stadium truck body is securely held in place with a hidden retention system that looks clean and professional. You don't need to remove the body to change the battery, but it's easy to take off if you need to access the on-board electronics for maintenance or upgrades.
• Easy to Upgrade and Customise — The VORTEKS accepts a wide range of optional parts and upgrades that are already available from ARRMA. As you gain experience, you can stretch the performance envelope and customise your truck to match your driving style and skill level.
• Spektrum 2-in-1 40A ESC and Receiver — This integrated unit combines the electronic speed controller and receiver in one compact package, saving weight and space whilst providing reliable wireless control. The unit is waterproof, meaning you can bash through wet conditions without worry.
• Spektrum SLT2 2.4GHz 2-Channel Transmitter — The included radio system operates on the secure 2.4GHz frequency and features a speed limiter function that lets you restrict the truck to 50% or 75% throttle whilst you're learning. This is an excellent safety feature for new RC drivers.
• High-Torque Spektrum S660 Digital Steering Servo — This waterproof servo delivers 84 ounce-inches of torque at 6V, providing the steering force needed for precise, responsive control even during aggressive driving. The high torque means steering response is sharp and controlled in all conditions.
• Waterproof Electronics — Both the Spektrum 2-in-1 40A ESC/receiver unit and the Spektrum S660 servo are waterproof, so you can confidently bash through wet conditions, muddy tracks and water crossings without concern about water damage to critical electronics.
• MEGA 550 14T Brushed Motor — The included brushed motor is proven, reliable and provides plenty of power for exciting bashing straight out of the box. The 550 motor size is ideal for 1/10 scale vehicles, delivering a great balance of speed and torque.
• Spektrum 8.4V 3300mAh 7-Cell Smart NiMH Battery — The included high-capacity battery provides generous run times between charges. The Smart battery technology enables automatic safe charging when connected to the Spektrum S120 charger, and the battery is IC3 connector equipped.
• Spektrum S120 USB-C Smart Charger — This modern charger features USB-C connectivity for convenient charging from any USB-C power source. The Smart technology ensures safe, automatic charging of the included NiMH battery. When you upgrade to LiPo batteries, this same charger is already compatible with 2S Smart LiPo packs.
• 2S LiPo-Ready Electronics — The Spektrum ESC and receiver are already calibrated and ready to accept 2S LiPo batteries. This means when you're ready for more power, you can simply swap in a LiPo battery without needing to replace or reprogram any electronics.
• Strong Composite Chassis — The durable composite chassis is engineered to withstand punishing terrain without cracking or breaking. The simple spine design won't collect dirt, rocks and mud, keeping the truck clean and lightweight for better power delivery.
• Mesh-Safe Motor Plates — The motor mounting system features mesh-safe motor plates that protect the motor from debris and impacts without compromising cooling or airflow.
• Composite Front and Rear Bumpers — Both bumpers are made from composite material to absorb impacts and protect the frame from damage during aggressive driving and crashes.
• Adjustable Ride Height — The suspension geometry allows you to adjust ground clearance to suit different terrain. Higher clearance helps over rough, bumpy ground, whilst lower ride height can be used for smoother surfaces.
• Independent Suspension with Oil-Filled Shocks — The independent suspension layout keeps all four wheels in contact with the ground through corners. Oil-filled coilover shocks absorb bumps and maintain traction over uneven surfaces, providing a smooth ride that inspires confidence.
• Tough Grey Multi-Spoke Wheels — The wheels are lightweight yet durable, featuring a classic multi-spoke design in grey that complements the aggressive orange body styling.
• All-Terrain Tyres — The dBoots Dirtrunner ST front tyres and all-terrain rear tyres provide excellent grip on a variety of surfaces, from grass to dirt to pavement, making this truck versatile for different driving environments.
• Low Stadium Truck Body Style — The low-slung, sporty body style reduces wind resistance and keeps the centre of gravity low for better handling and cornering performance.

The all-terrain dBoots Dirtrunner ST tyres grip well on various surfaces from dry ground to wet conditions. Electronics are waterproof-rated, meaning puddles and light rain won't damage the ESC, receiver or servo. The truck weighs 2.34kg without battery and 2.78kg with the included Spektrum Smart 3300mAh 7-cell NiMH battery. Battery dimensions are 156 x 51 x 48mm with IC3 connectors.

Frequently Asked Questions

• Is the ARRMA VORTEKS 2WD suitable for complete beginners to RC? — Yes, absolutely. The VORTEKS is specifically designed as an entry-level, ready-to-run RC car UK that requires zero assembly or additional purchases. The included Spektrum SLT2 transmitter features a speed limiter that restricts throttle to 50% or 75%, allowing you to learn control skills safely before accessing full power. The truck's wide stance and independent suspension make it stable and forgiving, whilst the easy-to-use two-channel radio is intuitive. Everything needed to drive is included, and the instruction manual provides clear guidance for new drivers.
• What battery does the VORTEKS 2WD use and how long does it last? — The truck comes with a Spektrum 8.4V 3300mAh 7-cell Smart NiMH battery using an IC3 connector. Typical run time with this battery is 20-30 minutes of continuous driving, depending on driving style and terrain. The Spektrum S120 charger provides fast 2-3 hour charge times. When you're ready for more power and longer run times, the Spektrum electronics are compatible with 2S LiPo batteries, which offer extended runtime and increased performance.
• Can I upgrade this truck to brushless power? — Yes, the VORTEKS is brushless-ready. The heavy-duty metal gear differential and transmission are designed to handle brushless motor upgrades whenever you decide to step up in power. The Spektrum SLT 2-in-1 40A ESC is already LiPo-compatible, so you can upgrade to a brushless motor and 2S LiPo battery simultaneously without replacing electronics. Optional brushless motors and higher-capacity LiPo batteries are available through ARRMA dealers.
• How fast does the VORTEKS 2WD go? — The VORTEKS delivers over 20mph top speed with the included MEGA 550 brushed motor and 7-cell NiMH battery. This is plenty of speed for exciting bashing and learning driving skills without being uncontrollably fast for beginners. Upgrading to brushless power and 2S LiPo batteries will increase top speed significantly for more experienced drivers.
• Is the VORTEKS waterproof? — The Spektrum 2-in-1 40A ESC/receiver unit and the Spektrum S660 servo are both waterproof-rated, meaning you can confidently bash through wet conditions, muddy tracks and water crossings. However, always refer to the instruction manual for specific waterproof standards and limitations. The motor is not waterproof, so avoid deep water immersion.
• What is the difference between the VORTEKS 2WD and other ARRMA 1/10 stadium trucks? — The VORTEKS 2WD is specifically designed as the most affordable hobby-quality 1/10 scale stadium truck available. It delivers refined performance with the perfect combination of stability and agility at a lower price point than other ARRMA models. The 2WD drivetrain makes it simpler and more affordable than 4WD options, whilst still delivering responsive handling and plenty of speed for bashing and learning.
• What tools and maintenance items are included? — The box includes high-quality moulded tools for basic maintenance and adjustment. An instruction manual with detailed diagrams and specifications is provided. Optional replacement parts and upgrade components are available separately through ARRMA dealers and RC specialists.
• How do I change the battery? — The VORTEKS features an easy-access bottom-loading battery tray. Simply push on the latches underneath the truck, open the battery door, unplug the discharged battery and plug in a charged one. You don't need to remove the body or any other parts, making battery swaps quick and convenient between driving sessions.
• Does this truck need any additional purchases to start driving? — No. The VORTEKS is a genuine ready-to-run RTR vehicle with everything included: truck, battery, charger, transmitter, receiver, motor, servo and electronics. You can open the box and be driving within hours. The only optional upgrade mentioned in documentation is the Spektrum 65W USB-C GaN Power Supply, which is recommended but not required.
• What type of terrain can the VORTEKS handle? — The dBoots Dirtrunner ST front tyres and all-terrain rear tyres provide excellent grip on grass, dirt, pavement and mixed terrain. The adjustable suspension and oil-filled shocks handle rough, bumpy ground well. The waterproof electronics allow wet conditions and muddy terrain without damage. This makes the VORTEKS versatile for back garden bashing, park driving and track use.
