The world of micro RC helicopters has long promised the thrill of 3D aerobatics in a backyard-friendly package, but often at the cost of durability, complexity, or performance. Enter the GOOSKY S2 Ultra, a helicopter that isn’t just an incremental update but a significant leap forward, designed from the ground up to shatter expectations. This Bind-and-Fly (BNF) model is poised to become the new benchmark for enthusiasts and aspiring 3D pilots alike.
So, what makes the GOOSKY S2 Ultra so special? It’s a masterful blend of cutting-edge technology, robust engineering, and user-friendly design.

1. Uncompromising Direct-Drive Power
At the heart of the S2 Ultra is its dual brushless direct-drive motor system. Unlike traditional models that use a main motor with a separate tail motor, the S2 Ultra employs a single, powerful outrunner brushless motor that drives both the main and tail rotors through a torque tube.
-
Superior Power & Efficiency: This design delivers instantaneous, silky-smooth power to the main blades for explosive climbs and tic-tocs, while providing unmatched tail authority for razor-sharp pirouettes and stability in backwards flight.
-
Eliminates Tail Blowouts: Say goodbye to the frustrating “tail blowouts” common in micro helicopters with separate tail motors. The direct-drive torque tube ensures the tail holds firm, even during the most aggressive maneuvers.
2. The Brains: Rotorflight Flight Control System
The S2 Ultra isn’t just powered by advanced hardware; it’s smart. It comes pre-installed with a Rotorflight flight control system. For those in the know, Rotorflight is an open-source firmware, akin to Betaflight for drones, renowned for its incredible customization and performance.
-
Pro-Level Tuning: This gives pilots unparalleled control over their helicopter’s behavior. From fine-tuning rates and expo to adjusting the PID gains for a perfectly locked-in feel, the possibilities are nearly endless.
-
Future-Proof: Being open-source means the system is constantly improved by a global community, ensuring your helicopter’s brain is always at the forefront of technology.

3. A Chassis Built to Survive and Thrive
GOOSKY understands that learning 3D flight involves a learning curve, and that curve often includes unexpected encounters with the ground. The S2 Ultra is built with durability as a core principle.
-
Carbon Fiber & CNC Metal: The frame utilizes a combination of lightweight yet incredibly strong carbon fiber and precision CNC-machined metal components. This creates a rigid, vibration-free platform that can withstand crashes that would leave other micro helis in pieces.
-
Strategic Design: Key components like the servos and the flight controller are strategically placed within the robust frame for protection.
4. BNF Convenience Meets High-End Performance
As a Bind-and-Fly model, the S2 Ultra comes fully assembled with the flight controller, servos, and motor installed. All you need is your own compatible DSMX/DSM2 or Futaba S-FHSS transmitter, a 3S 450mAh LiPo battery, and a charger. This removes the barrier of a complex build, allowing pilots to get into the air quickly while still offering a high-performance, customizable platform.

Who is the GOOSKY S2 Ultra For?
-
The Intermediate Pilot Looking to Advance: If you’ve mastered the basics on a fixed-pitch or smaller collective-pitch heli and are ready to dive into true 3D flight, the S2 Ultra is the perfect trainer. Its durability and incredible stability give you the confidence to push your limits.
-
The Seasoned Expert Seeking a “Backyard Beast”: Even for experienced pilots, the S2 Ultra is a joy. Its powerful, precise performance makes it an ideal machine for practicing new routines close to home without the hassle of traveling to a field.
-
The Tinkerer: For the pilot who loves to tweak and optimize, the Rotorflight FC is a dream come true, offering a level of adjustment typically reserved for large, expensive kits.

Conclusion
GOOSKY S2 Ultra is more than just another micro helicopter. It represents a convergence of powerful direct-drive mechanics, intelligent open-source software, and a nearly indestructible design. It successfully bridges the gap between a beginner-friendly BNF model and a pro-level 3D machine.
Whether you’re looking to unlock the world of inverted flight or you’re a seasoned veteran wanting a convenient and capable practice bird, the GOOSKY S2 Ultra delivers an unparalleled flying experience that is sure to impress. It’s not just a step forward; it’s a giant leap for micro heli kind.
