This document provides instructions for using the engine governor for the Futaba GV-1 model helicopter, including setting precautions, operating precautions, assembly and adjustment steps, and function descriptions.
The Futaba GV-1 is an engine governor designed for model helicopters that automatically maintains constant rotor RPM by suppressing variations in engine speed due to load changes. It features a magnetic sensing system, an LCD panel for displaying engine speed and set data, and allows fuel mixture control settings.
This instruction manual covers precautions, assembly, adjustment of the magnet and sensor, connection details, and descriptions of various functions including the LCD display and edit keys. It also includes reference specifications, parameter sheets, and repair service information.
