Default TruTrac Gemini as PFD?

Would like to hear from gemini users regarding using it as my primary flight display. I am VFR day only and realize it does not have a true attitude indicator. Thinking about pairing it with an IFly gps. Thanks

I think they are very good instruments, but IMHO, they have a reliability problem.

It works good when you park it, then next time you fly itís cold, it locked at 15 degrees of bank.

I never trusted my pitch and bank with that instrument.

If you are going to spend that much money, get a Dynon D10A and have a real EFIS.

Had mine for about 20 hours and it went to a 90 degree bank angle on startup. No way to reset or cage it. Removed it and sent it back to TruTrak for warranty service. Itís worked flawlessly since then. Currently 280 hours on the aircraft. I use it as a standby attitude indicator. Primary is a Dynon FightDek 180. GPS source for heading input is from an iFly720. Any attitude indicator can fail. IMHO with over 22k hours of flying, cross reference all instruments. Attitude indicators fail, solid state or vacuum, thatís why we practice and are trained for no gyro approaches. In a pinch, the iFly has a basic attitude indicator too.

My opinion is that I wouldn't want a smaller screen EFIS as my PFD.

I have a Gemini installed as a backup and tie breaker EFIS. All I say is that I would choose another product if I was going to do it again.

I had problems getting it to pass certifications tests. Lucas wanted the aircraft to be warmed up to pass the test. After three years of complaining about failing the certification test, he finally swapped the unit out this past year. I haven't attempt to get the new unit certified.

I have had no issues with my Garmin G5 that replaced it, and I cannot recommend the Gemini to anyone

I put one in the RV-6 about five years ago, and over almost 500 hours it never gave a false indication or misbehaved.

I think there are better options now. For my eyes it is too small. Check out the Garmin G5
