Virpil CM3 has 2 rotary encoders. (HDG and Alt)
I also have my old CM2 which also has 2 rotary encoders and finally I have 2 Koolertron programmable keypads one of which is is mapped to allow me to increase or decrease Altitude. (Depending on aircraft type sometimes the rotary encoder increments seem a little too small. The keypad mapping allows for fairly coarse adjustment if I just hold “up” or “down”
