WOLFBUSH Bell-47 2.4G 450-Class 3-Blade RC Helicopter with H1PRO Flight Controller (RTF) Pre-sale

Features: Premium Shaft‑Driven Structure for Professional‑Grade Performance Different from ordinary belt‑driven RC models, this helicopter adopts a high‑end shaft‑driven power system paired with precise professional gear sets. It features low power‑transmission loss, high transmission efficiency, quiet operation with no slippage, and consistent stable power output. The robust design delivers high durability and low failure rates. It is a rare professional‑level scale helicopter whose flight feel and playability far outperform other models in its class. Optimized Professional Gear Ratio for Smooth, Stutter‑Free Flight Equipped with a complete professional gear set (16T/151T/61T/13T) and a well‑tuned golden gear ratio of 9.44:1:4.69. It delivers smooth and even power output with vibration‑free, jitter‑free rotor operation. It supports rock‑solid hovering and agile steering, and is equally suitable for beginner basic practice and advanced aerobatic maneuvers. High‑Power Brushless Power System for Strong Output and Long Service Life Comes standard with a high‑performance 2000KV brushless motor and a 60A professional brushless ESC. It offers snappy throttle response and powerful thrust, together with excellent heat dissipation and overload resistance. It reliably sustains long‑duration flights and various aerobatic moves. Compared with traditional brushed helicopters, it delivers enhanced overall performance and a greatly extended service life. DFC Direct Flight Control System: Precise Control with High Fault Tolerance Adopting the advanced DFC link‑free direct‑flight control structure, together with three swashplate servos plus an independent tail servo. It simplifies the fuselage drive mechanism and effectively eliminates issues such as fuselage drift and tail wag. It provides delicate, responsive handling and stable, predictable flight attitude, making it easy for beginners to pilot. 4S High‑Capacity Lithium Battery: Stable Power Output Without Voltage Sag Supplied with a dedicated Grepow 4000 mAh 4S lithium‑polymer battery and a matching professional charger. The battery features high energy density and stable voltage output, supports numerous charge‑discharge cycles, and is safe and durable. It prevents sudden voltage drop or power cutoff during flight, extends overall flight time, and meets demands for long‑duration flying. 12‑Channel Professional Transmitter: Strong Anti‑Interference for Enhanced Safety Fitted with the RadioLink T12D PRO 2.4 GHz 12‑channel transmitter. It provides stable signal transmission with powerful long‑range anti‑interference capability. It allows fine‑tuning of multi‑dimensional flight parameters to unlock advanced aerobatic maneuvers, lowering risks of signal loss and fly‑away, and fully safeguards flight safety. CNC Full‑Metal Airframe + Hand‑Crafted Mesh Tail for Premium Build Quality The airframe uses high‑precision CNC one‑piece‑cut full‑metal frame, delivering outstanding structural rigidity, deformation resistance and vibration suppression, which greatly improves flight stability and overall durability. It is matched with an exclusive hand‑crafted mesh tail with fine workmanship and a highly realistic three‑dimensional shape. Unlike typical plastic‑bodied models, it combines robust mechanical strength with premium craftsmanship for upgraded appearance and durability. Openable Cockpit Doors + Simulated Instrument Panel for Authentic Full‑Scale Replica The fuselage features openable realistic cockpit doors. Inside sits a finely replicated instrument panel and complete cockpit structure, delivering authentic BELL‑47 full‑scale cockpit details. It breaks the monotonous plain‑shell look of ordinary RC models with superior realism, three‑dimensional visual effect and display value. Highly collectible, it is an ideal choice for scale‑model helicopter enthusiasts.
