GOOSKY Legend RS5 ULTRA – Helicopter Kit

The GOOSKY Legend RS5 ULTRA brings the RS5 platform to the next level, combining an aggressive new ULTRA design with the precision, rigidity and high-end engineering expected from GOOSKY.

Designed for demanding pilots, the RS5 ULTRA is a high-performance 550/560 class electric helicopter, equally capable of smooth precision flying and extreme 3D.

Its extremely rigid airframe, oversized drivetrain components and precision CNC-machined parts provide excellent control accuracy and durability, while the compact 560-class format delivers an outstanding power-to-weight ratio.

The RS5 platform features high-quality 7075 aluminium CNC components, high-strength 12.9-grade hardware and high-precision bearings throughout the drivetrain.

The oversized swashplate and specially designed rotor head provide excellent cyclic authority while maintaining smooth and precise control.

A strong 12 mm main shaft, 8 mm feathering shaft and one-piece 6 mm tail shaft provide the rigidity required for demanding high-RPM 3D flying.

The tail is belt driven with a 6 mm wide belt, providing a simple, efficient and reliable transmission system.
