Technical Performance

The Volantex Atomic SR85 Brushless Boat represents professional-grade RC boat engineering designed specifically for speed enthusiasts. The 3720/1750KV water-cooled brushless motor is a sophisticated piece of engineering that delivers consistent, high-output power whilst remaining thermally stable through extended use. The 1750KV specification means the motor achieves approximately 1750 revolutions per minute under 1-volt load, translating to explosive acceleration and sustained high-velocity performance when paired with 14.8V lithium polymer batteries. The water-cooling system circulates water through the motor jacket, preventing thermal degradation and allowing the motor to operate at peak efficiency continuously, something that air-cooled alternatives simply cannot achieve.

The 60A water-cooled ESC (electronic speed control) is engineered specifically for high-performance brushless applications, capable of handling the substantial power draw from the brushless motor whilst providing responsive throttle control and essential protection features. The XT60 connector has become the industry standard for high-power RC applications, offering lower resistance than older connector types and providing secure connections that don't accidentally disconnect during impact. The ABS blow-moulded hull combines excellent impact absorption with light weight — critical when pursuing top speeds in brushless RC boat racing. The specially designed hull shape delivers stability over rough water, preventing the boat from becoming unstable at high velocities where lesser hulls would bounce and skip uncontrollably. The self-righting feature means capsize recovery is automatic, minimising the time the boat spends upside down and reducing the risk of water ingress into the electronics.

The anodised aluminium rudder and drive assembly represents a significant engineering investment, delivering corrosion resistance that steel components simply cannot match. After exposure to saltwater, freshwater minerals or chlorinated pool water, anodised aluminium maintains its structural integrity and responsiveness, whereas bare steel would rapidly corrode and lose performance. The 40g waterproof servo ensures that your steering input is translated immediately and accurately to the rudder, with the waterproof seal protecting against water entry even if the boat is submerged. The 2.4GHz radio system operates on a frequency band with 79 available channels, virtually eliminating interference issues when multiple boats operate simultaneously — a common problem with older 27MHz and 35MHz systems.

Frequently Asked Questions

• How fast does the Volantex Atomic SR85 go? — With the correct battery configuration (14.8V LiPo packs), the Atomic SR85 reaches speeds of up to 75kph, making it one of the fastest brushless RC boats available in the UK market. Actual top speed depends on battery capacity, water conditions and payload weight, but serious speed runs are absolutely achievable with this boat.
• What batteries does the Atomic SR85 require? — The boat requires either a single 14.8V 5000mAh LiPo battery or two 7.4V 5000mAh LiPo batteries connected in parallel to achieve the 14.8V nominal voltage required for full performance. These are standard 4S (four-cell) LiPo configurations, widely available from RC hobby retailers across the UK.
• Is the Atomic SR85 suitable for beginners? — The Atomic SR85 is primarily designed for experienced RC boat operators who understand brushless motor systems, LiPo battery safety and high-performance boat handling. The forward-only operation and responsive steering make it moderately easy to control, but the extreme speed and power delivery demand respect and experience. Beginners should consider slower brushed alternatives before progressing to this brushless model.
• Does the Atomic SR85 come with batteries and charger? — The Atomic SR85 is sold as a NO BATT (no battery) package, meaning batteries and charger are not included. You must purchase compatible 14.8V LiPo batteries and a suitable charger separately, though this approach allows you to choose batteries that match your specific performance requirements and budget.
• How does the self-righting feature work? — The hull shape is specifically engineered so that when the boat capsizes, the centre of buoyancy automatically returns the boat to the upright position. This isn't an electronic system — it's pure hydrodynamic design that ensures the boat naturally flips back over, getting you back to racing almost instantly without requiring manual recovery.
• Can the Atomic SR85 handle saltwater? — Yes, the anodised aluminium hardware and waterproof servo are designed to withstand saltwater exposure. However, you should rinse the boat thoroughly with fresh water after every saltwater session to remove salt residue and prevent corrosion of any exposed metal surfaces. The water-cooling system is particularly important in saltwater applications because it helps dissipate heat generated by the motor more effectively.
• What is the difference between the Atomic SR85 and other Volantex RC boats? — The Atomic SR85 represents Volantex's flagship brushless high-speed boat, featuring water cooling on both the motor and ESC — a technology not found on slower, brushed alternatives like the Vector series. The SR85 is optimised purely for speed and performance, whereas other Volantex boats in their range prioritise affordability or different performance characteristics such as self-righting or off-road capability.
• How long will the battery last on a single charge? — Runtime depends on your driving style, battery capacity and water conditions, but typical high-speed performance runs generate 15-25 minutes of continuous operation from a 5000mAh battery before throttle-down from voltage sag occurs. Running at moderate speeds rather than continuous maximum throttle will extend runtime significantly.
• Is the 2.4GHz radio system reliable? — Yes, the 2.4GHz digital transmission protocol offers excellent range, responsiveness and security. The 79 available channels mean you can operate multiple boats simultaneously without interference, and the digital signal provides more reliable communication than older analogue 27MHz or 35MHz systems that are prone to frequency congestion.
