A few months ago, I had a major avionics upgrade done on my J. Overall I am more than pleased with the install. One chronic issue that I’m having though is the pitch trim servo on the GFC-500 is not moving the trim up much past the take-off indication point before it just stops. The old autopilot that was removed was an S-Tec 55 and that pitch trim servo had no problem moving the trim to wherever I wanted it. So, I’m not sure if there’s a problem with the GFC-500 servo itself, or there just too much friction in my trim system that the Garmin servo can’t handle it. It does seem tight with the hand wheel when it goes much past the take-off indication. The tech who installed GFC-500 said that it does feel tight, but not as tight as some of the Saratogas that he’s worked on. He said the GFC-500 servo works OK on them. He suspects a bad servo. Anyone else run into this problem? John

As the title says... any leads or suggestions appreciated! Repair or exchange. im fairly sure the engagement coil or the circuit that drives the coil are what is bad on mine.

Looking for collective wisdom. The last few flights, shortly after start with everything turned on, our KFC200 system would start beeping at us. If we press the test button it goes away for maybe 15 seconds and then comes back on. Usually it only does that a few times and then stays quiet. Yesterday, instead of beeping at us, after we got airborne the elevator trim/CB turned off. We reset it and it turned off again a few seconds later. We flew for about 2 hours with it off using manual trim. Then on the 3rd leg of the day we decided to try turning it on again and it worked fine. However, even though the trim was working, they system started beeping at us again. While it was beeping I turned off the elevator trim and the beeping stopped. The flight director still works fine. After landing we ran the manual trim through the limits and did not find any binding but we did notice that it takes quite a bit more effort to trim nose up than nose down. However, that kind of makes sense. When trimming nose down, we are moving the tail down and gravity is helping us. When trimming nose up, we are working against gravity. I'm thinking this is a problem somewhere in the elevator trim system, and most likely the servo. What do you think? Thanks
