I've been communicating with the G3xperts on this but I want to run this by the community as well. Looking for ideas and leads to help trace an issue.
On my 8A the 5 Volt elevator pitch trim indicator voltage is non linear during calibration. This makes it difficult to find neutral pitch trim using the trim indication on the G3X. You have to use eyeballs instead. I've recalibrated it at least 4 times with the same results.
Fortunately, roll Trim Voltage is linear and working as expected. Both trim motors are working as expected throughout their travel.
Pitch trim motor indicator voltage (Ray Allen) checked out as linear throughout its movement on the bench.
We've swapped out the GEA-24 and that is not the problem.
Maybe somebody has seen this before and has a fix...Next attempt to fix will be to take everything apart. So hard to take it down - it's too much fun to fly.
Other info: Pitch trim on the stick with coolie hat (Infinity), GMC 305 autopilot (auto pitch trim turned off) and roll and trim relays installed.
