Goosky Legend RS5 ULTRA Helicopter Kit

Goosky Legend RS5 ULTRA Helicopter Kit

The Goosky Legend RS5 ULTRA is a helicopter kit for pilots who want to build and tune their own 6S machine. Its 1:1 flybarless rotor-head geometry, three-layer frame, and adjustable tail linkage combine precise control with a reinforced mechanical platform.

Choose Glacier Blue or Danxia Orange, with or without Azure blades, then select the electronics to suit your build. The RS5 ULTRA requires full-size cyclic and rudder servos; mini-size servos are not compatible.

Explore the kit at HeliDirect or browse more RC Helicopters to find the model that fits your flying goals.

RS5 ULTRA Kit Options

Choose your color and blade package before planning the rest of the build. Glacier Blue and Danxia Orange are available with either option.

With Azure Blades

Glacier Blue — With Azure Blades

Choose Glacier Blue with the Azure blade bundle. Check the exact blade model, length, and quantities with HeliDirect before ordering.

Danxia Orange — With Azure Blades

Choose Danxia Orange with the Azure blade bundle. Confirm the bundle details when completing your component list.

Without Azure Blades

Glacier Blue — Without Blades

Choose the Glacier Blue finish and select compatible blades separately for your build.

Danxia Orange — Without Blades

Choose the Danxia Orange finish and pair the kit with your preferred compatible blades.

Photos show the helicopter’s appearance; pictured electronics are not a packing list. Both blade options require assembly and setup.

Kit Contents and Completion Items

Start with the RS5 ULTRA kit in your chosen color and blade configuration. Select Without Blades if you want to choose blades separately, or With Azure Blades if you prefer the Azure bundle.

Before ordering, ask HeliDirect for the selected kit’s itemized contents and exact Azure bundle details. This helps you avoid buying duplicate parts and identify what you still need to complete the helicopter.

Recommended Electronics for Your Build

These are setup recommendations, not a list of included electronics. Check your motor, ESC, servos, flybarless controller, radio system, battery, and charger against the kit contents and assembly requirements before purchasing.

Use the Goosky manual resources linked from the product page to find the RS5 ULTRA assembly instructions.

Technical Specifications

The approximately 2.68kg weight excludes the battery. Final weight varies with the electronics and battery you install.

Check your battery’s dimensions, leads, and mounting clearance before choosing a pack. Capacity alone does not guarantee a fit.

Goosky RS5 ULTRA Design Features

The RS5 ULTRA combines rotor-head precision, drivetrain support, and practical access for assembly and maintenance. Each feature below addresses a specific part of the build or control system.

1:1 FBL Rotor-Head Geometry

The RS5 ULTRA uses a 1:1 rotor-head control ratio for precise cyclic input. Its flybarless geometry is designed for accurate response as you tune the helicopter to your flying style.

Integrated POM Blade-Grip Spacers

Integrated, self-lubricating POM blade-grip spacers simplify installation and maintenance. Their quick-install design makes the rotor-head assembly easier to work on.

Three-Layer Main Frame

A reinforced three-layer frame provides a rigid foundation for the RS5 ULTRA. The structure supports the drivetrain and control system during demanding flight.

Reinforced Main Gear

The RS5 ULTRA uses a reinforced 116T main gear with a 14mm thickness. The gear is designed to handle drivetrain torque under demanding flying conditions.

Automatic Belt Tensioning

A self-adjusting tensioner helps maintain consistent belt tension during operation. It supports reliable power transmission while you follow the manual’s belt inspection and setup guidance.

Two-Position Tail-Pitch Bellcrank

Two bellcrank positions let you adjust the tail-control geometry. Choose and set up the linkage position according to the manual when tuning tail response.

Raised Tail Rotor and Revised Belt Guides

A raised tail output shaft brings the tail-rotor plane closer to the main-rotor plane to help reduce pitch coupling during pirouettes. Revised belt guides and idlers support the belt under load.

Carbon-Fiber Tail Boom

The RS5 ULTRA features a carbon-fiber tail boom for a rigid, lightweight tail structure. It supports the tail assembly while keeping the airframe focused on responsive control.

Expanded Battery Compartment

The battery compartment measures 300 × 62 × 56mm for planning your 6S installation. Check your pack’s dimensions and cable clearance when selecting a recommended 5000–5500mAh battery.

Quick-Release Canopy

Quick-release canopy mounts make the canopy easier to install and remove. You can access the battery and work on the helicopter more conveniently between sessions.

Plan the 6S Electronics Before Ordering

Use a 4025-1100KV motor and 150A LV ESC as the recommended starting point for a 6S build. Check the actual motor dimensions, mounting pattern, and ESC installation requirements before buying.

Choose full-size cyclic and rudder servos. If you are transferring equipment from another helicopter, check the servo dimensions and mounting requirements first; mini-size units will not fit this kit.

For the battery, start with the recommended 6S 5000–5500mAh range and check physical fit in the 300 × 62 × 56mm compartment. Leave room for the leads and confirm that your connectors and charger match the chosen power system.

Before completing your order:

• Confirm your selected color and blade package.
• Check blade compatibility and any Azure bundle contents.
• Verify motor and ESC fit.
• Select compatible full-size servos.
• Match the flybarless controller, receiver, and transmitter to your setup.
• Check battery fit, connectors, and charging requirements.

Who Is the RS5 ULTRA For?

Choose the RS5 ULTRA if you want to assemble a 6S helicopter and tune its rotor and tail controls around your own equipment choices. It suits pilots comfortable with kit assembly and electronic setup, or builders working with experienced help.

Allow time for the complete build and setup before your first flight. This is a helicopter kit, so check the completion requirements before ordering.

Without Blades or With Azure Blades?

Both options are available in Glacier Blue and Danxia Orange. Choosing the Azure bundle does not make the helicopter ready to fly; plan the electronics, assembly, and setup for either option.
