The GOOSKY Legend RS4 is a powerful 380-class, high-performance, innovative, aerobatic helicopter that incorporates all the latest in cutting-edge design and technology to bring you unmatched flying fun and excitement. It boasts a whole host of features including a flybarless head, high-power direct-drive main motor, belt-driven tail rotor system, 2nd generation GTS flight controller with Bluetooth mobile phone APP for parameter adjustments, and a 70A intelligent speed controller with slow start. Every detail reflects the ingenuity of the GOOSKY R&D team in producing a tough, exciting-to-fly, low-maintenance, high-performance helicopter, that is suitable for high-end 3D and aerobatic flying.

The Legend RS4 is supplied as an unassembled kit that does require assembly, but being the combo version it is supplied with everything you need (apart from assembly tools) to get you flying apart from a transmitter, receiver, and a LiPo battery charger. The power system at the heart of the RS4 is a high-performance iron core, hand-wound brushless motor with high-speed bearings and NdFeB magnets. This motor coupled with the supplied 6S battery, and the 70A continuous intelligent speed controller, brings an infinite amount of power for even the most demanding of pilots.

The GTS flight control system utilizes 2nd generation algorithmic technology for precision control of the flybarless head and tail rotor. The parameters of this system such as gyro settings, control throws, pitch, and head speeds are fully adjustable via the GOOSKY mobile phone APP using the supplied Bluetooth module, this makes setting up and fine-tuning a breeze. The ingenious design of the center structure with built-in bearing alignment brings strength and support to the cyclic control system, and the supplied metal-geared high-power servos provide a precise, fast, and accurate control response.

Other features of the Legend RS4 include high-strength aluminum alloy main blade grips, high-precision tail rotor design with O-ring damping and a unique monorail-guided tail control system, an angled battery compartment for quick battery changes, strong thick-walled tail boom for stability in aggressive 3D flying, and a high strength, lightweight one-piece landing gear.

This incredibly powerful 3D helicopter is a must-have for all experienced RC heli pilots, it will deliver thrilling flights, outstanding performance, and unforgettable aerial adventures.
