G20 tail gyroscope user manual, introduces the product features, installation, connection, setting information
The G20 tail gyro is a lightweight, MEMS‑based stabilizer for RC helicopters. It offers dual‑range servo output (1520 µs and 760 µs) and high‑speed spin up to 1080°/s. The manual covers safety precautions, hardware parameters, installation, connection, transmitter configuration, LED status displays, flight modes and mechanical adjustments.
Key sections include detailed hardware specifications, step‑by‑step installation on the aircraft, wiring diagrams for the tail servo and receiver, how to configure the transmitter for lock‑tail or rate mode, interpretation of the LED indicators, procedures for entering and exiting setting mode, and a troubleshooting guide for common flight issues. This manual is written in Chinese.

It requires at least 4 seconds of startup time while the aircraft remains still and the rudder stick is centered.
The gyro offers two modes: lock‑tail mode (positive transmitter sensitivity) and rate mode (negative sensitivity).
In lock‑tail mode, keep the aircraft still and hold full left or right rudder for more than 3 seconds; the left LED will flash purple to indicate setting mode.
