I had trouble with my servo when installing the flaps gauge from OpenCockpits. The motor was moving in a very funny manner and I got tired of trying to fix it. I then remembered that FDS had done a flaps indicator using some sort of LEDs. I looked around for what I had and found a face plate I could use. Trouble was that I needed to have the LED directly on the slots so the light shines there without “leaking” to nearby flaps position. I found some small black plastic tube which I cut to size and inserted the LEDs into them.
I then used hot glue to hold everything in place as can be seen above. The result was not so bad as can be seen below.
The only problem I have now is getting the values of the flap position to be precise. I am getting different values each time for the same position. An indication that my flaps handle on the TQ is not properly calibrated and is bouncing about. One day at a time I guess.
