Technical Performance

The Volantex Arrobolt Lumen SR40 represents a genuine engineering achievement in compact brushless RC boat design. At the heart of the vessel lies a water-cooled brushless motor paired with integrated 180A brushless ESC (Electronic Speed Controller) that delivers seamless power delivery and responsive throttle control. The motor is specifically engineered for aquatic environments where traditional air-cooled designs would struggle; the water-cooling system maintains optimal operating temperatures even during extended high-speed runs, preserving motor longevity and ensuring consistent performance lap after lap. The 180A ESC provides more than sufficient current capacity for the 11.1V 3S Li-ion battery system, enabling rapid acceleration and sustained high-speed operation without thermal throttling or performance degradation. The brushless motor design eliminates the maintenance requirements of traditional brushed motors whilst delivering superior efficiency, meaning more of your battery's energy is converted into forward motion rather than wasted as heat. The 11.1V 1000mAh 3S Li-ion battery provides a typical run time of 10 to 13 minutes at full throttle, offering a satisfying duration for recreational racing or multiple heat races in competition. The included EU-compatible balance charger ensures safe, efficient battery charging and extends battery lifespan through intelligent cell balancing. The durable ABS plastic hull is engineered for low resistance through the water, combining hydrodynamic efficiency with impact resistance. Measuring 40 centimetres in length with a beam width of 12 centimetres and standing 66 millimetres in height, the compact dimensions ensure excellent manoeuvrability in confined water bodies whilst maintaining the structural rigidity necessary for high-speed stability. The running weight of approximately 210 grams strikes the perfect balance between manoeuvrability and stability, allowing the boat to achieve impressive speeds without sacrificing the handling characteristics that make racing enjoyable. The fully integrated waterproof electronics bay utilises a single-cover sealing system that keeps water out whilst minimising weight penalties. Construction quality is evidenced by the upgraded anti-collision silicone head, which protects the bow from impact damage during inevitable contact with docks, banks and obstacles — a thoughtful design choice that significantly extends the serviceable life of the boat.
