To resolve the Detrum Z3 flight controller's green light flashing issue, follow these optimized troubleshooting steps designed to be simple yet effective, meeting the needs of RC model enthusiasts.

1) Check the Wiring: Ensure that only one signal wire is connected to the flight controller. If there are two, keep just one to avoid interference or unnecessary issues.
2) Gyro Calibration: The flight controller must remain stationary during calibration. Make sure the Z3 flight controller is securely mounted; otherwise, the gyro will continuously attempt calibration, causing the signal light to flash.
3) Receiver Signal Mode Optimization: Ensure the receiver supports PPM mode and set it to PPM output. The Z3 flight controller is highly compatible with PPM signals, while other signal modes may cause flashing issues. The Z3 also supports Futaba SBUS and Spektrum DSM signals (ensure you're using original receivers, not compatible ones, for better signal stability). Selecting the correct signal mode helps avoid signal conflicts and enhances flight stability and control accuracy.
4) Receiver Gyro Settings: If the receiver has a built-in gyro, it's recommended to disable it. If you cannot turn off the receiver's gyro function, consider switching to a receiver without a built-in gyro. The Z3 controller already has a built-in gyro, and dual gyros can cause signal conflicts, negatively impacting flight performance.
5) Recommended Optimized Option: If the problem persists, consider purchasing the Detrum Blitz-DTP 9CH Transmitter w/ SR86A-G package. This product has been optimized for better compatibility with the Z3 flight controller, effectively reducing signal issues such as flashing lights.

By following these steps, you can significantly improve signal stability between the flight controller and receiver, eliminating the green light flashing issue, and providing RC enthusiasts with a safer, smoother flying experience.
Detrum Z3 Flight Controller is designed for fixed-wing RC planes, compatible with conventional wing, delta wing, and V-tail configurations. It offers several enhanced flight control features ideal for RC modelers seeking better stability and safety in flight:

Flight Modes: Supports multiple modes, including Normal Stabilization (basic gyro control), Safe Mode (for altitude and direction stabilization), 3D Lock (for holding position), and Return-to-Home (RTH). When the signal is lost or manually triggered, RTH automatically returns the plane to its takeoff point.
Sensors and Processor: Equipped with a 32-bit ARM core processor and 6-axis MEMS gyro chip for high-performance stability control. It’s compatible with major 2.4GHz systems like DSM, SBUS, and PWM receivers.
Programming and Parameter Adjustment: With the Detrum 3-in-1 program card, users can easily adjust gain and other settings to suit their preferences. It works seamlessly with the Detrum Blitz DT-9 transmitter and RCX9m receiver system, offering real-time telemetry for altitude, speed, and distance data.

Automatic Calibration: Features an innovative horizontal calibration method that doesn't require a computer or power reset, simplifying the setup process.
In summary, the Detrum Z3 Flight Controller provides excellent stabilization and recovery options, making it the ideal choice for pilots looking to enhance safety and control performance. It's particularly suited for RC enthusiasts aiming for a more reliable and optimized flight experience.
