Key Features
- 2S and 3S Ready Power System — Unlike many RC bashers that lock you into a single battery voltage, the SENTON 223S BLX accepts both 2S LiPo batteries for 35+ mph performance and 3S batteries for 50+ mph pro-level speeds, allowing you to start small and scale up your performance without replacing the entire truck.
- Spektrum Dynamic Stability Control (DSC) — The integrated DSC system offers four selectable modes that automatically apply steering corrections to improve your control, confidence and safety whether you're bashing on high-grip or low-grip surfaces, making it ideal for learning without fear of losing control.
- Throttle Limiting for Progressive Learning — The included Spektrum SLT3 transmitter features an intelligent throttle limiter switch that automatically limits top speed to 50% or 75% of full capability until you're ready for maximum performance, ensuring a smooth learning curve from beginner to advanced driver.
- Super-Tough 4X4 Drivetrain — The heavy-duty 4WD system with centre differential and all-metal gear differential sends power from the Spektrum 3100Kv brushless motor to all four wheels, providing blasting power through challenging terrain whilst the entire power system remains well-protected for dependable performance.
- All-Terrain Independent Suspension — Adjustable oil-filled coilover shocks mounted on composite shock towers soak up bumps and impacts, with ride height adjustment capability to increase ground clearance when bashing over uneven surfaces.
- Waterproof Spektrum Electronics — Both the Spektrum SLT 80A 2-in-1 brushless 2S/3S ESC and receiver unit and the Spektrum S662 metal-geared digital steering servo are waterproof, allowing you to bash without fear in wet conditions and muddy environments.
- Aggressive Short Course Body Design — The securely mounted closed-wheel short course truck body with hidden body retention system lets you aim for the block pass in racing scenarios without worrying about getting tangled in competitor's tyres, whilst the clipless design features inbuilt dirt protection.
- Impact-Absorbing Protection — Impact-absorbing composite front and rear bumpers, strong composite nerf bars, and higher extended chassis side guards provide maximum protection from dirt, debris, and collisions during aggressive bashing sessions.
- Premium Build Quality Materials — Tough metal and composite materials are used throughout for an easy-to-maintain, super-durable design that can handle extreme bashing punishment whilst remaining simple to service and upgrade.
- Spektrum 2.4GHz Radio System — The high-quality Spektrum SLT3 3-channel transmitter operates at 2.4GHz with excellent range and responsiveness, giving you reliable control at distance with four AA batteries included in the box.
Technical Performance
The SENTON 223S BLX 4X4 is engineered with a powerful Spektrum 3100Kv brushless motor paired with a 35mm motor cooling fan, ensuring consistent performance during extended bashing sessions. The Spektrum SLT 80A 2-in-1 waterproof ESC and receiver unit handles both 2S and 3S LiPo batteries seamlessly, eliminating the need to purchase separate electronics when upgrading battery voltage. With 2S power delivering 35+ mph and 3S delivering 50+ mph, this brushless RC short course truck offers a wide performance range that grows with your skills. The ventilated composite chassis measures 558mm in length, 305mm in width, and 210mm in height, with a wheelbase of 327mm, creating a compact yet stable platform for high-speed racing and bashing.

Frequently Asked Questions
- Is the ARRMA SENTON 223S BLX suitable for RC beginners? — Yes, absolutely. This truck is specifically designed for brushless bashing newcomers. The Dynamic Stability Control (DSC) system automatically corrects steering inputs to help prevent crashes, whilst the throttle limiter lets you cap maximum speed at 50% or 75% until you've developed proper control skills. You can start with a 2S battery for manageable 35+ mph speeds, then upgrade to 3S as you improve. This progressive approach makes it one of the best ready to run RC trucks for learning brushless driving.
- What is the difference between 2S and 3S battery performance? — The 2S battery (7.4V) delivers 35+ mph top speed, whilst the 3S battery (11.1V) unlocks the full 50+ mph potential. Both batteries work with the truck's electronics without modification. You control which battery to use depending on your skill level and desired speed. 2S is perfect for learning and general bashing, whilst 3S is for experienced drivers seeking pro-level performance.
- What is included with this RC truck and what do I need to buy separately? — The truck comes complete with motor, ESC, receiver, transmitter, and servo, making it truly ready to run. You only need to purchase a 2S or 3S LiPo battery with IC5 connector (5000mAh recommended), a battery charger, and ideally a LiPo charging bag for safety. Everything else needed to start driving is included in the box.
- How waterproof are the electronics on this short course truck? — Both the Spektrum SLT 80A ESC/receiver unit and the Spektrum S662 servo feature waterproof housing, allowing you to bash in wet conditions without fear. For specific waterproof ratings and protection standards, refer to the detailed instruction manual included with your truck.
- Can I upgrade components on this truck later? — Yes, the SENTON 223S BLX is designed for easy maintenance and the ARRMA platform has extensive spare parts availability. You can upgrade shocks, servos, suspension components, and other parts as you progress, though the integrated ESC/receiver unit cannot be replaced without losing the DSC stability control feature.
- What is the runtime per battery charge? — Runtime varies depending on driving style, terrain, and battery capacity, but users report approximately 10-15 minutes of continuous running on quality 5000mAh batteries. Conservative driving and varied terrain use may extend this further.
- Is this truck good for racing or just bashing? — The SENTON 223S BLX is equally suited for both. The closed-wheel short course design is competition-ready, whilst the robust construction handles aggressive recreational bashing. The short course truck format is popular in organised short course racing events across the UK.
