FLYWING BELL-412 V4 470-Class RC Military Helicopter – 2.4G 6CH, Quick-Detach Props, ACE Flight Controller & GPS(Pre-Sale)

Difference between H1 and ACE flight controller

Features:

• True-to-Life Scale Design with Intelligent Navigation: This BELL-412 470-class RC helicopter features a realistic scale body, powered by a high-performance 16V motor for stable flight and simple maintenance. The integrated H1 flight controller with omnidirectional positioning and Beidou GPS supports upright and inverted position hold, ensuring easy control and automatic return-to-home when battery is low or out of range.
• Quick-Detachable Four-Propeller Rotor Head： for Enhanced Stability: Equipped with a FBL (flybarless) rotor structure, it delivers a smoother and more responsive feel than traditional 450L DFC models. The reinforced swashplate design adds flight stability, while the 470L-grade main and spindle shafts provide durability for intensive flight.
• Industrial-Grade Drive System with Quick Maintenance: Features Customized NACA 8-H-12 flat-convex propeller, a full-metal main gear and M3 arc-tooth industrial transmission belt for strong and reliable performance. The torsion-spring belt pulley design allows for tool-free belt replacement in under a minute—perfect for quick repairs and maintenance in the field.
• High-Efficiency Powertrain for 3D Flight: Powered by a 3508-class high-torque brushless motor and a 32-bit 60A all-metal ESC, this helicopter is built for aggressive 3D maneuvers. The high-voltage 16V system ensures consistent power output, lightning-fast throttle response, and outstanding speed control throughout the entire flight.
• 4 Advanced Flight Modes for All Skill Levels: Choose from four flight modes: upright position hold, inverted position hold, auto-route. GPS-assisted hovering enables easy control for beginners, while 3D mode supports advanced stunts like flips, rolls, and inverted flying. Auto-route mode includes one-key circular and figure-eight paths. Inverted position hold makes upside-down flying simple and stable—even for newcomers.

Note:

• RC model helicopters are classified as high-risk products. Always keep a safe distance from people during flight. Improper assembly, unfamiliar operation, component damage, or malfunctioning electronic controls may lead to flight loss or unpredictable accidents. Pilots must exercise caution and fully accept personal responsibility for any incidents resulting from negligence.

Before each flight, thoroughly inspect all critical parts, including the main rotor grip spindle screws, tail rotor grip screws, and all ball links and screws throughout the helicopter. Ensure that all components are properly secured and thread-locked before attempting takeoff.
