Doug, I had my Gemini ADI fail within the first few hours of operation after my build. I had it installed for about a year before the initial flights. Didn?t get the grey screen but the attitude indication would go to a 90 degree bank and freeze. Airspeed, altitude and heading indications were not affected. Mine is just a standby indicator and I don?t have it connected to the autopilot. Sent it back to TruTrak (well before they sold out to Bendix) and according to them, all it needed was a software update. At this point I had owned it for about two years, past the warranty, but they fixed it up at no charge. Have had zero issues since then, 5 years, and close to 400 hours. I have to admit I did not trust the indicator for a while. Now, even after doing aerobatics, the Gemini has worked perfectly.
