Flywing H2 Helicopter Flight Control FBL Gyro (H1 Upgraded Version) with Dual GPS, CAN Bus, 12S Voltage Detection

Overview

The Flywing H2 Helicopter Flight Control is the H1 upgraded version FBL gyro/autopilot designed for RC helicopters. This flight control system integrates dual GPS (primary + secondary), anti‑interference CAN Bus connectivity, new high‑performance sensors, and advanced algorithms to improve stability, positioning, and handling across multiple helicopter configurations, including Chinook/tandem setups.

Key Features

• Dual redundant GPS design: primary module with Ublox M9N and CAN interface; secondary module with low‑power Ublox M10 for faster, more stable positioning.
• New generation sensors: ICM42688P gyroscope, IST8310 compass, and MS5611 barometer, paired with built‑in vibration damping and pure copper counterweights.
• Supports multiple airframe types: H3, HR3, 4‑servo, 6‑servo swashplate, plus added Chinook configuration (tandem).
• Retractable landing gear expansion: S6 port for PWM devices; supports up to 12V servos via BEC (set BEC to output 12V; remote CH9 control).
• GPS positioning mode and self‑stabilization mode with barometric altitude hold for flexible assisted flight.
• New Smart 3D Acro: stick‑controlled flips in any direction with automatic pitch compensation.
• Automatic rescue: when height drops below the user‑set value in intelligent stunt mode, switches to GPS mode and attempts stabilization.
• Turn Auto‑Tilt (coordinated turn): automatic aileron (roll) compensation during forward flight yaw to achieve banked turns and reduce turning radius.
• Slow takeoff and landing functions for realistic ascent/descent behavior.
• Three flight styles with one‑click switching: Soft, Standard, and Sport.
• Spin optimization algorithm with RPM filter to reduce blade resonance and improve attitude sensing.
• Voltage detection upgraded to 12S (51V max) for large 700‑class and above setups.
• Radio compass calibration via transmitter: toggle the mode switch 3–4 times; LED gradient light shows calibration progress.

Details

Intelligent Helicopter Flight Control System with Dual GPS and Anti-Interference, featuring CAN Bus technology and smart 3D aerobatic capabilities.

H3 and HR314 support various helicopter setups with Chinook 46 and 53 models, ideal for enthusiasts and professionals alike.

New Generation High-Performance Sensors feature ICM42688P Gyroscope, IST8310 Compass, and MS5611 Barometer for improved data accuracy and anti-interference, simplifying compass calibration. A built-in vibration damping design filters high-frequency vibrations, ensuring consistent sensor performance. The assembly includes a custom damping sponge, pure copper counterweights, and high-performance sensors mounted on a circuit board, all designed to enhance stability and precision in dynamic environments.

Dual redundant GPS with M9N and M10 Ublox chips. M9N primary module offers high performance and anti-interference via CAN; M10 secondary module provides low-power support, ensuring stable, faster positioning.

Features custom-designed sockets with foolproof GPS port layout, expanded spacing, and secure connectors for retractable landing gear. Supports up to 12V servos requiring a 12V BEC output. Includes S6 port for landing gear and other PWM devices, controllable via remote CH9—ensure adequate BEC power. Operates within a 5–12V range. Labeled ports include RC, 5V L, 5V R, S1 T, S3 B, ESC, and S6. A connected cable highlights seamless integration and reliable connectivity for efficient setup and control in demanding applications.

GPS Positioning Mode + Self-Stabilization Mode. Supports barometric altitude hold, enhances free flight with slight assistance, offers flexible operation.

New Smart 3D Acro introduces automatic pitch compensation for stick-flip maneuvers. Exceeding 90% stick input triggers flips; full stick enables continuous flips. Release to hover, re-engage for half-flip. Altitude loss may occur based on mechanical and power limits.

When flying in intelligent stunt mode, helicopter switches to GPS mode for stabilization if falls below set height. Set according to power and mechanical condition to avoid failure.

Turn Auto-Tilt enables automatic helicopter tilt during forward flight turns, reducing radius and enhancing banked posture. The controller compensates aileron roll based on stick input and speed for smoother maneuvers.

Flywing H2 FBL Gyro enables slow takeoff and landing, automatically rising to 1 meter before manual control. It regulates descent speed and offers software-configurable functions for realistic flight performance.

Three flight styles with one-click switching feature a flight controller that offers three built-in modes: Soft, Standard, and Sport.

Spin optimization algorithm and RPM filter ensure stable rotation, minimizing blade resonance for improved handling precision. Features labeled ports: RC IN, S1/L, S2/R, S3/B, S4/T, ESC, S5, S6, with CAN and UART support. Displays "H2" and includes an "AUTOPILOT" indicator. Side-mounted USB-C port and circular button. Background shows blurred code, highlighting technical design.

Voltage detection upgraded to 12S max (51V), resolving low-battery return issues in large helicopters. Features battery port and S+/- terminals.

Supports radio compass calibration by toggling the mode switch. Enter calibration mode, and the LED gradient light displays the current progress.
