Goosky RS7 ULTRA Helicopter Kit w/o Blades – Pink

Goosky RS7 ULTRA Helicopter Kit – No Blades (Pink)

The RS7 ULTRA is Goosky’s next-generation 700-class helicopter platform, built for pilots who demand performance, efficiency, and precision. This airframe integrates aerodynamic optimization, drivetrain improvements, and vibration reduction for stable and predictable flight characteristics.

Note: This kit does not include main or tail blades.

✔ Low-Drag Aerodynamic Design
Engineered airflow paths using ridge-line shaping and dual-curvature ducts reduce drag while improving cooling efficiency and flight stability.

✔ Reinforced Main Gear System
Larger diameter main gear with optimized helical angle increases torque transfer and drivetrain efficiency.

✔ Adaptive Belt Tensioner
Dual-shaft adjustable tensioner system ensures consistent belt performance and long-term reliability.

✔ Advanced Shock Absorption
Integrated vibration damping system reduces gyro interference and improves flight precision.

✔ Optimized Tail Assembly
Lightweight and refined geometry improves tail response, reduces load, and minimizes vibration.
