Key Features

• 40mm Water-Cooled Brushless Motor — The integrated water-cooling system keeps the motor at optimal operating temperature, enabling consistent high-speed performance throughout your session without power loss due to heat buildup. Brushless motors deliver superior efficiency compared to brushed alternatives, meaning longer run times and less maintenance.
• Top Speed Over 50 km/h (30+ mph) — This impressive velocity puts the Arrobolt SR40 among the fastest RC boats in its class, providing adrenaline-fuelled excitement whether you're racing against friends or simply enjoying the thrill of high-speed water operation.
• Self-Righting Hull Design — The innovative hull geometry automatically returns the boat to upright orientation if it capsizes or flips, eliminating frustrating recoveries and keeping you in control even when pushing the limits. This feature is particularly valuable for newer RC boat pilots who are still developing their water handling skills.
• Twin 7.4V LiPo Batteries with 30-Minute Runtime — Two included 7.4V LiPo batteries (1000–1500mAh capacity) deliver extended playtime of up to 30 minutes per charge, and the USB smart charger makes rapid battery management straightforward and convenient.
• Integrated Waterproof ESC with Full Forward and Reverse — The electronic speed controller is fully sealed against water ingress, ensuring reliability in wet conditions whilst providing seamless throttle response and reverse functionality for agile obstacle navigation and precise manoeuvring.
• 2.4GHz Pistol-Grip Transmitter with Proportional Control — The modern radio system operates on the licence-free 2.4GHz frequency band with proportional steering wheel and trigger throttle, delivering crisp, responsive control over steering and speed at any velocity. The 120-metre control range provides ample distance for exploration without signal loss.
• Rugged ABS Plastic Hull Construction — The durable ABS material resists impact damage and UV degradation, meaning the boat maintains its structural integrity and eye-catching blue finish through countless high-speed runs and occasional collisions with banks or obstacles.
• Compact 400mm Hull Length — At just 400 millimetres (15.75 inches) long, the Arrobolt SR40 is easily portable, fitting comfortably in a backpack or small carry case for transport to your favourite water venue, whilst remaining large enough for genuine high-speed performance.
• Almost Ready-to-Run Format — Supplied fully assembled and ARTR, this ready to run RC boat requires minimal preparation before deployment, making it ideal for newcomers to the hobby who want to avoid lengthy construction processes.

Technical Performance

The Volantex Arrobolt SR40 40mm Brushless Boat represents a sophisticated engineering achievement for its price point. The 40mm water-cooled brushless motor is purpose-designed for aquatic environments, with water circulation channelled through the motor housing to dissipate heat and maintain performance throughout extended sessions. This engineering approach contrasts sharply with air-cooled designs, which can experience thermal throttling during sustained high-speed operation. The integrated waterproof ESC handles full forward and reverse throttle commands with smooth proportional response, ensuring the boat behaves predictably across its entire speed range from idle to maximum velocity. Power delivery comes from two 7.4V LiPo battery packs (1000–1500mAh capacity), which when used alternately extend your water time to approximately 30 minutes total—more than sufficient for recreational sessions whilst remaining practical for charging cycles using the included USB smart charger. The hull material is durable ABS plastic, chosen for its excellent impact resistance and UV stability; unlike softer materials that degrade in sunlight, ABS maintains structural rigidity and aesthetic appeal through months of regular use. The self-righting mechanism is elegantly incorporated into the low-drag racing hull profile, meaning the hydrodynamic advantages of the streamlined shape are not compromised by recovery features. The 2.4GHz radio system provides a 120-metre control range, more than adequate for recreational water venues, whilst the proportional control systems in both steering servo and throttle ESC ensure smooth, natural handling characteristics that experienced RC boat pilots will appreciate.

Frequently Asked Questions

• Is the Volantex Arrobolt SR40 suitable for beginners to RC boating? — Yes, the ARTR format means no assembly is required, and the self-righting hull design automatically corrects capsizes, reducing frustration during the learning curve. The proportional control system is intuitive and responsive, making it easy for newcomers to develop smooth steering and throttle skills. However, some basic understanding of LiPo battery safety and radio transmitter operation is advisable before first use.
• What battery does this RC boat need and how long do they last? — The Arrobolt SR40 uses two 7.4V LiPo batteries (1000–1500mAh capacity), both included in the box. Each battery provides approximately 15 minutes of runtime, so operating both batteries sequentially gives you up to 30 minutes total playtime per charging cycle. The included USB smart charger handles both batteries and provides automatic charge termination for safety.
• How fast does the Arrobolt SR40 go and is it suitable for racing? — The boat achieves speeds over 50 km/h (30+ mph), making it competitive for casual racing and extremely entertaining for recreational use. The 40mm brushless motor and waterproof ESC provide smooth, responsive acceleration and throttle control, though serious competitive racers may seek dedicated racing variants with higher-capacity batteries or upgraded power systems.
• What happens if the boat flips over in water? — The self-righting hull design automatically flips the boat upright without intervention, meaning you can immediately resume operation. This feature is one of the Arrobolt SR40's most valuable assets for recreational boaters, eliminating the tedious process of wading in or using a net for recovery.
• How does the brushless motor compare to brushed alternatives? — Brushless motors are dramatically more efficient than brushed designs, converting a higher percentage of electrical energy into propulsive force whilst producing less heat. This translates to longer runtime, reduced maintenance (no brush wear), and superior performance consistency throughout the battery discharge cycle. For serious RC boat enthusiasts in the UK, brushless technology is now the standard expectation.
• Is the Arrobolt SR40 waterproof? — The ESC is fully integrated and waterproof, and the motor features water-cooling channels, so the boat can safely operate in normal water conditions. However, you should avoid submerging the radio transmitter or allowing salt water to contact electronics; freshwater venues (lakes, ponds, rivers) are ideal, and thorough rinsing after saltwater use is essential if you choose to operate near coasts.
• What is the control range of the 2.4GHz transmitter? — The pistol-grip transmitter provides reliable control out to approximately 120 metres, more than adequate for most recreational water venues. The 2.4GHz frequency band is licence-free in the UK and many other countries, eliminating regulatory complications.
