This document describes the features and characteristics of the GY502 AVCS gyro, designed for use with .60 type and other model helicopters.
The Futaba GY502 is an Angular Vector Control System (AVCS) rate gyro designed specifically for use with .60 type and other model helicopters. It features high-speed arithmetic processing via a microcomputer to allow high-speed pulse drive of servos, making it compatible with high-speed digital servos. The unit includes a sensor vibration-resistant low back aerofoam case and an amplifier-mounted LCD for accurate data setting.

A high-speed digital servo especially developed for gyro use is recommended, as higher speed and response allow for better gyro gain.
Avoid sudden temperature changes by allowing the model to stand for about 10 minutes before turning on power after moving it from extreme temperatures.
Do not move the helicopter or the transmitter rudder stick from the neutral position until the 'Hello' message disappears.
