Joysway Monster Brushless Catamaran Speed Boat – 570mm – 2.4GHz RTR

At the heart of the Monster is a water-cooled brushless outrunner motor, paired with a 30A water-cooled brushless ESC with BEC for reliable power delivery and consistent performance during extended high-speed runs. Power is transferred through a robust 3 mm flex cable drive system, commonly found in high-performance RC boats.

The catamaran hull offers several advantages over conventional boat designs. Its twin sponsons reduce drag, improve stability and allow the hull to ride efficiently across the water at speed. Combined with a waterproof metal gear servo, aluminum rudder and three-blade propeller, Monster provides responsive handling and an exciting driving experience.

This is a complete RTR (Ready-To-Run) package including an 11.1V 3S LiPo battery and balance charger, allowing you to get on the water with minimal preparation. Only AA batteries for the transmitter are required separately.

Catamaran Performance at High Speed

Catamaran hulls are designed to minimize water resistance and maximize efficiency. Their twin-hull design allows the boat to ride higher on the water, reducing drag and improving acceleration. Monster performs best on calm lakes, reservoirs and larger open waterways, where its brushless power system and offshore-inspired hull can fully showcase their capabilities. The wide hull layout provides exceptional stability and delivers an exciting offshore racing experience.
