GOOSKY RS5 Ultra

The Goosky Legend RS5 Ultra is a premier 550/560-class electric RC helicopter kit engineered for aggressive 3D aerobatics and high-precision flight. Building upon the engineering of the RS7 Ultra platform, this kit features a high-rigidity multi-layer carbon frame paired with CNC-machined 7075 aluminum components and premium 12.9-grade hardware. Its upgraded symmetrical cyclic servo layout provides true linear swashplate travel, while the 1:1 flybarless rotor-head geometry delivers instantaneous cyclic response and razor-sharp control. Outfitted with a heavy-duty 12 mm (0.47 in) main shaft, an 8 mm (0.31 in) feathering shaft, a rigid 30 mm (1.18 in) carbon tail boom, and an efficient 6 mm (0.24 in) belt-driven tail transmission, the RS5 Ultra effortlessly handles high-load maneuvers. Complete with a practical slide-in battery tray, it delivers exceptional power-to-weight performance for serious 6S 3D pilots.

Features:

• Symmetrical Servo Layout & 1:1 FBL Geometry: Symmetrical cyclic servo geometry provides uniform, linear control rod displacement across full swashplate travel, combined with a 1:1 flybarless rotor head for direct and precise cyclic input.
• Heavy-Duty Drivetrain System: Built for extreme loads using a reinforced 12 mm (0.47 in) main shaft, an 8 mm (0.31 in) spindle feathering shaft, and a rigid 6 mm (0.24 in) tail shaft.
• Optimized 550/560-Class Airframe: Designed around 560 mm (22.05 in) main blades and 95 mm (3.74 in) tail blades, yielding an overall length of 1,159 mm (45.63 in) and a rotor diameter of 1,272 mm (50.08 in).
• Premium CNC 7075 & Carbon Construction: Utilizes high-strength CNC-machined 7075 aluminum bearing blocks, high-grade 12.9 hardware, and a 30 mm (1.18 in) carbon fiber tail boom.
• Belt-Driven Tail & Slide-In Battery Tray: Features a durable 6 mm (0.24 in) belt-driven tail transmission (4.6875:1 ratio) and a 245 × 52 × 60 mm (9.65 × 2.05 × 2.36 in) quick-access slide-in battery compartment
