I'm the OP of this thread, and just saw that this topic is being discussed again. I thought I should update now that everything is working fine now.
I originally had my POS-12 mounted on a piano hinge mounted on the aft spar with the arm connected to a small bracket on an adel clamp. Others have done it this way, although the people I saw weren't using G3x system.
The piano hinge may or may not have been hindering the function of my position sensor. The reason I don't know, is because I later found out that it wasn't the root cause.
Here are some observations that may or may not have played a part in my situation: - The play in the hinge pin accounted for several mV of error and would never return to close to the pre-configured mV setting. (yes, the pos-12 was within its accurate range of travel)
- At one point, I had configured the flaps to stop just shy of being fully retracted. This doesn't work because the flap motor will coast a small amount after power is cut from it.
- I ended up relocating my POS-12 to a bracket just like Mike Starkey did that can be seen in this link. With this design, everything is solid with no play. This made a big difference, however, the flap switch still only worked about half the time on the ground, and never in flight. http://www.vansairforce.com/communit...highlight=flap
- After several emails back & forth to Garmin, we discovered that I never entered a "Partial Flap Max Airspeed". I remembered seeing this during my initial configuration. I had a reason in my head at the time why I felt I should leave it blank, but now I can't remember. I also failed to see the note in the manual that stated that the value must be greater than the full flap airspeed. After entering a value in this field, my predetermined flap settings have worked ever since.
I'm sure the main issue all along was this simple mistake I made in the software configuration. The other changes I made may, or may not have mattered.
Hope this helps someone.
