I have configured setup as described in steppers/28byj-48 section.
It seems to be working, cause when i use the "SimVim Gauge Calibration" i can make the gauge go around the clock, both slow and fast.
I then set the dataref values for flaps at 0,1,2,5,10,15,25,30 and 40, in correct positions.
Back in the cockpit, i then move flaps stick to test, but now the gauge only move VERY tiny steps.
I can hear that whenever flaps needle is moving in X-plane, the physical guage motor is moving, but i can barely see it.
