The Goosky Legend S2 Ultra represents modern helicopter technology in an ultra-compact scale. With a main rotor diameter of 444 mm, the S2 Ultra positions itself in the high-performance micro and mini 3D helicopter segment. This model is specifically designed for experienced pilots seeking a precise, reliable, and uncompromising 3D workhorse.

The S2 Ultra utilizes a Rotorflight system with an external ESC. Combined with brushless direct drives for the main and tail rotors, this results in extremely direct, powerful, and sensitive control characteristics. The drive system provides ample thrust reserves at all times, making it ideal for hard pitch changes, rapid directional maneuvers, and demanding 3D flight.

The all-metal servos ensure high precision and stability, even under heavy loads. The overall system is supported by a mechanical construction made of CNC-machined aluminum and robust carbon fiber, which enables high rigidity and precise control.

At the heart of the model is the high-performance FBL controller with exclusive Rotorflight 2.2 tuning. Thanks to the STM32F405 processor and ICM42688P 6-axis sensors, the S2 Ultra achieves response times in the millisecond range. Even during aggressive maneuvers, the flight behavior remains precise, stable, and highly predictable.

An integrated 128 MB black box stores over 60 flight data logs, enabling detailed analysis and precise fine-tuning with a single click.

The S2 Ultra fully supports ELRS (ExpressLRS). Pre-configured programs are available for some Radiomaster transmitters and are included with your purchase. FBL system configuration is conveniently performed via a LUA script on the transmitter.

DSMX and S-BUS systems are also supported – however, this requires in-depth knowledge of transmitter programming and Rotorflight setup.

Visually, the Goosky Legend S2 Ultra impresses with a streamlined canopy in exclusive Flow Ink Phantom Premium paint, giving the model a distinctive and high-quality look.

All in all, the S2 Ultra is a high-precision 3D model for demanding users – designed for pilots who make no compromises and are looking for a reliable setup for tough 3D use.


Note regarding radio and FBL configuration:
For the use of transmitters with S-BUS, DSMX satellites, or similar systems, suitable receivers are required. Furthermore, sound knowledge of transmitter and FBL unit programming is necessary.
