B737 VOR ADF RMI

Another self-designed Gauge of my B737 collection.... Fully functional 737-style VOR ADF RMI with 3 stepper motors (28BYJ) and a clockwork mechanism to drive the compass and both digits independently. For the VOR/ADF selectors use two small push-buttons (6x6mm) and insert a spring between the "gehaeuse" and "schalterteil innen". The axis of the knobs is made of 4mm steel.
