The gyros used in helicopters are integrated PID controllers. It takes an input from the receiver as the set point, compares it to the internal sensor value, and outputs the PWM signal required to match the rates. There are potentiometers to adjust the gain. As such, they aren't suitable for integrating the heading because you don't have access to the raw sensor output. I don't think they are high precision parts but I don't know for sure.
