Product Features:
1. High-Precision Rotor Head: CNC-machined high-precision DFC rotor head. Its metallic finish delivers a significant visual upgrade. Enhanced precision effectively reduces in-flight vibration and wear. The DFC rotor head features a lower centre of gravity and compact structure, providing superior power performance.
2. Highly authentic exterior detailing: Faithfully recreates the appearance of the genuine UH-1N helicopter, with near-scale exhaust ports, windows, and windscreen meticulously rendered for unparalleled realism.
3. Authentic cockpit replication for an immersive flight experience.
4. FLISHRC's exclusive L7 flight controller. Utilising an H7 processor operating at 480MHz, its processing power quadruples that of the commonly used STM32F405 processors in other flight controllers, enabling significantly faster data processing. The H7 processor also incorporates a double-precision floating-point unit for higher-precision control.
5. The GPS positioning module incorporates advanced quad-mode capability (BeiDou, GPS, Galileo, QZSS). By integrating multiple positioning systems, it significantly enhances positioning accuracy, reliability, and anti-interference performance. The L7 flight controller paired with quad-mode GPS delivers faster satellite acquisition, more precise positioning, more stable flight, and smoother operation.
6. Altitude Hold, Stationary Flight, and Beginner-Friendly Operation: Leveraging the L7 flight controller's high-precision calculations and GPS positioning, the helicopter effortlessly achieves self-stabilising flight and altitude/position holding. This enables instant takeoff upon stick input and immediate hovering when released. No additional adjustments are required to maintain flight posture. Beginners can effortlessly experience the thrill of flight, while seasoned pilots can abandon cumbersome controls to fully appreciate the elegant flight dynamics reminiscent of real helicopters.
7. High-Performance Sensor Board Dual-Channel IMU: Equipped with dual ICM42688P IMUs and an SPL-06 barometer, this high-performance, highly redundant design delivers superior data accuracy and enhanced interference resistance for greater safety and reliability. Integrated shock absorption effectively minimises vibration-induced data errors, ensuring the flight controller consistently receives precise readings. Bluetooth parameter adjustment functionality enables more convenient debugging.

 L7 Flight Control Functions:
1. GPS Stabilisation Mode
2. Attitude Mode
3. 6G Mode
4. Low Battery Return
5. One-Touch Return to Home
6. Loss of Control Return
7. Bluetooth Parameter Adjustment - Data Transmission
8. Quad-Constellation Positioning: BeiDou, GPS, Galileo, and QZSS Satellites

Important Notes: Radio-controlled model helicopters are high-risk products. When flying, maintain a safe distance from crowds. Improper assembly, unfamiliar operation, damaged components, faulty electronic controls, or lack of proficiency may lead to unpredictable accidents such as loss of control or injury. Operators must prioritise flight safety and acknowledge personal liability for any incidents arising from negligence. Before each flight, meticulously inspect the main rotor hub cross-shaft screw, tail rotor hub screw, and all ball joints and screws throughout the airframe. Ensure all fastenings are securely glued and tightened before commencing flight.
