The GOOSKY RS5 Ultra is the new generation of GOOSKY 550-class helicopters and has been developed with a strong focus on performance, precision and high durability. With its modern Ultra design, high-quality mechanics and numerous technical improvements, the RS5 Ultra is aimed at pilots looking for a powerful 550-size helicopter for sport flying, precise aerobatics and dynamic 3D flight.
The Glacier Blue version combines a striking, highly visible appearance with a well-engineered construction and many upgrades compared to conventional 550-class concepts.
The RS5 Ultra carries forward the performance-focused design philosophy of the GOOSKY Ultra series. Its construction was developed with direct flight response, high structural rigidity and competition-level flight performance in mind.
The model combines a modern, aggressive appearance with a practical mechanical design that impresses during assembly, setup and maintenance.

With an overall length of 1157 mm, a main rotor diameter of 1272 mm and 560 mm main blades, the RS5 Ultra offers a well-balanced combination of compact 550-class size, high flight performance and excellent visibility in the air.
The generous battery compartment allows flexible battery setups and supports clean weight distribution inside the model.
The RS5 Ultra impresses with high-quality mechanics, precisely manufactured components and a modern, service-friendly construction. The combination of carbon fiber, aluminum and optimized plastic components provides high stability while keeping the overall weight low.
The striking canopy and matching design ensure excellent orientation in the air and give the model a premium, dynamic appearance.
The reinforced three-layer frame design increases the overall structural rigidity of the model. This creates a stronger central chassis and delivers improved precision, higher durability and better stability in flight.
Especially during fast load changes, powerful maneuvers and demanding 3D flight, the rigid frame structure provides a precise and predictable flight feel.
The RS5 Ultra features integrated POM spacers in the blade grips. The self-lubricating material ensures smoother operation, reduces wear and makes assembly and maintenance easier.
This solution supports clean rotor head response and also contributes to the long service life of the components.
The rotor head of the RS5 Ultra uses a 1:1 control geometry. This provides higher control resolution, more precise cyclic input and faster response to pilot commands.
The result is a very direct, controlled and performance-oriented flight feel — ideal for pilots who value precise handling and accurate control response.
The upgraded high-strength main gear is designed to handle higher torque loads and improves drivetrain durability under demanding flight conditions.
Especially with powerful setups, fast pitch changes and dynamic 3D flying, the reinforced main gear provides additional reserves and reliability.
A self-adjusting belt tensioner maintains consistent belt tension during operation. This improves transmission efficiency and drivetrain reliability.
The automatic system reduces maintenance effort and ensures that the tail drive works reliably and consistently, even under changing loads.
The quick-release canopy mounting system allows particularly fast installation and removal. Battery changes, setup work and routine maintenance become much more convenient.
The canopy can be securely mounted and quickly removed when needed — a practical detail for everyday use at the flying field.
The larger battery compartment accommodates a wider range of battery sizes and configurations. This gives pilots more flexibility when setting up the model and adjusting weight distribution.
With a battery compartment size of 300 × 62 × 56 mm, the RS5 Ultra can be adapted very well to different flying styles and power requirements.
The upgraded carbon-fiber tail boom increases bending strength by 38% while reducing weight by 30 g. This lowers the load on the tail servo and delivers faster, more precise tail performance.
The combination of low weight and high strength supports a particularly direct tail response and improves performance during fast direction changes.
The tail output shaft has been raised by 14%. This brings the tail rotor plane closer to the main rotor plane and can help reduce pitch coupling during pirouettes.
A newly designed guide and idler pulley assembly improves belt support and load distribution. This extends belt service life and increases resistance to belt skipping under high-load conditions.
The RS5 Ultra features a two-position adjustable tail pitch bellcrank. This allows the tail linkage to be adapted to the desired flying style and provides higher control resolution as well as faster response.
This detail enables finer tuning of the tail behavior — from stable and controlled to especially direct and agile.
The GOOSKY RS5 Ultra is a modern 550-class performance helicopter with many well-thought-out design details. Three-layer frame structure, 1:1 FBL rotor head geometry, reinforced main gear, automatic belt tensioning, carbon-fiber tail boom and optimized tail system make it a powerful platform for ambitious pilots.
Pilots looking for a high-quality 550-class helicopter with precise flight behavior, strong mechanics and modern Ultra styling will find the GOOSKY RS5 Ultra a very attractive solution for sport flying and demanding 3D maneuvers.
