Product Description:
1. Rare-axis drive structure—industry-leading high-end configuration for professional performance
Unlike ordinary belt-driven model helicopters, this model features a high-end, rare shaft-driven power transmission system paired with a precise, professional gear train. It offers low power transmission loss and high transmission efficiency, operates quietly without slippage, and delivers continuous, stable power output. The structure is more durable and has a lower failure rate. This is a professional-grade, scale helicopter configuration rarely seen on the market, with flight feel and playability far surpassing ordinary models in the same class.
2. Professional “Golden Ratio” Gear Ratio for Smooth, Stutter-Free Flight
Equipped with a complete set of professional gears (16T/151T/61T/13T) and featuring a scientifically optimized “golden ratio” of 9.44:1:4.69, this model delivers uniform and smooth power output. The rotors operate without vibration or stuttering, enabling stable hovering and agile maneuvering—effortlessly accommodating both beginner training and advanced aerobatic maneuvers.
3. High-Power Brushless Propulsion: Powerful, Long-Lasting, and Durable
Equipped as standard with a 2000KV high-performance brushless motor and a 60A professional brushless ESC, it delivers rapid throttle response and ample power output. With excellent heat dissipation and overload resistance, it reliably supports extended flight times and various aerobatic maneuvers. Compared to traditional brushed models, it offers superior overall performance and a significantly extended service life.
4. DFC Direct Control System: Precise Control with High Error Tolerance
Features an advanced DFC (Direct Flight Control) linkage-free control structure, paired with three swashplate servos and an independent tail servo. This simplifies the airframe’s transmission structure and effectively eliminates issues such as airframe drift and tail wobble. The control feel is smooth and responsive, ensuring a stable and controllable flight attitude that even beginners can master with ease.
5. High-Capacity 4S Lithium Battery: Stable Flight Time Without Voltage Drop
Equipped with a GES 4000mAh 4S dedicated lithium battery and a matching professional charger, this battery features high energy density and stable voltage output. It supports multiple charge cycles, is safe and durable, and resists degradation. There are no sudden voltage drops or power cuts during flight, effectively extending overall flight time to meet the demands of extended flight sessions.
6. 12-Channel Professional Remote Control: Enhanced Interference Resistance and Safety
Equipped with the LeDi T12D PRO 2.4GHz 12-channel remote controller, it offers stable signal transmission and strong long-range interference resistance. It supports multi-dimensional fine-tuning of flight parameters, enabling a wide range of advanced aerobatic maneuvers, while effectively preventing risks such as signal loss or loss of control during flight, ensuring comprehensive flight safety.
7. CNC-Machined All-Metal Frame + Handcrafted Mesh Tail Fin: Premium Build Quality
The entire aircraft features a high-precision, CNC-machined, one-piece all-metal frame that offers high structural rigidity, resistance to deformation, and vibration damping, significantly enhancing flight stability and overall durability. Paired with a custom, handcrafted mesh tail section—characterized by meticulous craftsmanship and a three-dimensional, lifelike design—it stands apart from ordinary plastic airframes by combining robust structural strength with a premium, high-end aesthetic, delivering a dual upgrade in both visual appeal and durability.
8. Openable Cockpit Door + Simulated Instrument Panel: Ultimate Real-Aircraft Replication
The fuselage features an opening and closing simulated cockpit door, housing a meticulously replicated real-aircraft instrument panel and a complete cockpit structure. With exquisite and rich detailing, it fully recreates the texture of the BELL-47’s actual cockpit, breaking away from the monotony of standard model aircraft’s solid-color shells. It maximizes realism, three-dimensionality, and display appeal, offering exceptional collectible and aesthetic value—making it the top choice for enthusiasts of realistic model aircraft.
