This gyroscope uses digital PID control method. It has a built-in temperature compensation circuit and thus greatly reduces the impact of temperature change on the midpoint offset. It has the two working modes: lock mode and standard mode. With multi-gain control and many adjust method, this gyro can perform head-lock function with ease.It is easy to fit different kinds of helicopters. It is a good choice for hovering, flying routes, reverse flight and other stunt flying.
