Features

Low-Drag Aerodynamic Shape Design

Integrating multiple low-drag aerodynamic solutions: The top ridge line splits the airflow like a blade, while the double-curvature air ducts direct the air precisely into the cooling channels. The inward-turning edge design reduces vortex formation, and the entire canopy features a low-resistance, streamlined profile that balances heat dissipation efficiency with increased stability by minimizing flight drag

Main Gear Reinforcement

The main gear features a larger diameter design, with an optimized increase in the helical angle, improving transmission efficiency and increasing torque output

Adaptive Tensioner Wheel Design

Featuring an adjustable tensioner wheel, the S2 incorporates a dual-shaft reinforcement design and leverages top-tier CNC machining technology—all to provide a stable and reliable flight experience.

Shock Absorption System

Upgraded shock absorption system, designed with vibration filtering and cushioning, reduces airframe vibrations that interfere with the gyroscope, enabling more precise control

Tail Assembly

Featuring a lightweight design that reduces weight by 8g; the tail shaft is shortened by 9mm, lowering the load and reducing vibration; the geometry and pitch are optimized simultaneously, further enhancing tail response speed and control performance
