Hi Grant........sorry for not getting back sooner.........use any 3 position switch and set it up just like "Dual Rates", except that the so-called "Off" position should have "20" which will give you a "blue" light and the rate postion.......the middle position should have "50" and that will turn off the gyro and yield "no" light........lastly, the last position should have a value of "80" which will give you "heading hold" and a "red" light........good luck, and let me know how it goes.......
