The highly anticipated Goosky S2 Ultra has landed and is now ready for pre-order at HeliDirect! This new micro-helicopter redefines what's possible in a small airframe, blending professional-grade features with extreme durability. The S2 Ultra comes equipped with the advanced Rotorflight Flight Controller for next-level tunability and performance,upgraded full-metal servos for increased crash resistance, and a full carbon main frame for a strong structure and premium look. It also boasts more powerful, cooler-running motors and supports popular ELRS and Sbus receivers. The result is the ultimate versatile micro: stable enough for new pilots to use as a durable basher, yet capable of performing nearly all the extreme 3D maneuvers that even pro pilots demand from their large helicopters.   The new S2 Ultra introduces a level of customization and performance never before seen in a micro-class helicopter. At its core is the most advanced Flight Controller (FC) available, running the latest open-source Rotorflight firmware. This powerhouse FC gives you unparalleled control and features an onboard Blackbox chip to record essential flight data (current, voltage, headspeed), making performance tuning effortless and precise. Unmatched Power and Precision This micro helicopter is uniquely built for elite performance. Its ESCs run on AM32, a highly respected open-source firmware that provides both ESC signal and RPM telemetry on the same wire. This sophisticated integration translates directly into incredibly smooth, responsive power delivery, and allows you to monitor critical motor data in real-time. Tune it to Perfection Never before has a micro heli been this capable. While the S2 Ultra is absurdly capable right out of the box, its deep tuning capability means you can truly customize the flight characteristics to perfectly suit any pilot, any style, from smooth sport maneuvers to aggressive 3D action. Plus, with acceptance for SBUS, DSMX, and ELRS receivers, you get maximum compatibility with your preferred radio system.
