Goosky Legend RS4 Venom – Compact Size. Serious 3D Performance.
The Perfect Step Up from the S1 or S2!
Meet the Goosky Legend RS4 Venom, a high-performance 390-class electric RC helicopter that delivers impressive power, precision, and agility in a compact, convenient package.
Looking for something more capable than your S1 or S2 without moving up to a large 550 or 700-class helicopter? The RS4 Venom is an excellent choice! Its compact, traditional 450-class size makes it easy to transport and ideal for regular practice sessions at smaller, suitable outdoor flying fields. It's also a great everyday practice helicopter for experienced pilots who want serious 3D performance without bringing out their larger machines.
Featuring a powerful direct-drive brushless motor, rigid carbon fiber and aluminum construction, and an innovative variable-pitch tail system, the RS4 Venom combines exceptional performance with practical, maintenance-friendly engineering.
From smooth, controlled flying to aggressive 3D maneuvers, the RS4 Venom proves that you don't need a big helicopter to enjoy serious performance!
This complete electronics combo includes the main motor, servos, 80A ESC, FBL flight controller, Bluetooth module, and a 6S 2200mAh 70C LiPo battery.
Assembly required. Receiver and transmitter are not included.

Key Features
1. High-Power Direct-Drive Brushless Motor
At the heart of the RS4 Venom is a powerful, disc-type brushless main motor with a direct-drive design. This system eliminates the conventional main gear transmission, reducing mechanical complexity while delivering smooth and direct power to the rotor.
- High-output disc-type brushless main motor
- Direct-drive main rotor system
- Reduced transmission complexity and maintenance
- Metal motor protector included
- Designed for demanding 3D flight performance
2. Precision Flybarless Rotor Head
The RS4 Venom features a rigid flybarless rotor head with high-strength 7075 aluminum alloy blade grips, providing the strength and precise control response needed for aggressive flying.
- High-strength 7075 aluminum main blade grips
- Flybarless collective-pitch rotor head
- Precision-machined metal components
- Designed for responsive and accurate cyclic control
3. Variable-Pitch Belt-Driven Tail System
Unlike fixed-pitch motor-driven tail systems, the RS4 Venom uses a belt-driven variable-pitch tail for precise and responsive yaw control.
Its innovative monorail-guided tail control structure helps maintain smooth pitch movement, while the integrated tail shaft design and O-ring damping system contribute to reliable operation under demanding flight conditions.
- Belt-driven collective-pitch tail
- Monorail-guided tail pitch control
- One-piece precision tail shaft design
- O-ring damping system
- Reinforced tail boom construction
4. Lightweight Carbon Fiber and Aluminum Frame
The RS4 Venom combines carbon fiber structural components with aviation-grade aluminum alloy parts to achieve an excellent balance between rigidity, strength, and overall weight.
Its streamlined painted canopy provides a distinctive appearance while maintaining a clean and aerodynamic design.
- Lightweight carbon fiber frame construction
- Precision-machined aluminum components
- Rigid and compact airframe design
- Streamlined, low-resistance painted canopy
- Lightweight, impact-resistant nylon landing gear
5. Convenient Battery Access
The RS4 Venom features a quick-access battery mounting system, allowing pilots to replace the flight battery without removing the canopy.
This practical design makes battery changes faster and more convenient, allowing you to spend less time preparing and more time flying.
6. Complete Electronics Combo
This Combo version includes the major electronic components needed for the helicopter, including a powerful 80A ESC, high-precision cyclic and tail servos, an FBL flight controller, and a Bluetooth module for supported setup and adjustment functions.
A 6S 2200mAh 70C LiPo battery is also included, making this an excellent option for pilots looking for a comprehensive build package.
