    After about 50 flights, my Q500 4k will not hold GPS LOCK.

    Starts off in GPS lock sometimes but quickly changes to GPS Ready and has begun to lose GPS completely now, requiring a sweaty manual return to base and landing.

    I have tried the proverbial everything. It has never done this before and has been 100% reliable.

    Light on the tail is flashing orange with white flashes every few seconds.

    Lost my nerve now. Support and suggestions welcome.

    Yuneec costumer support at times like this is your best friend but sounds to me like a bad GPS unit. You might want to start there.
     
  3. Thank you very much. Apologies for the delay in replying.
    I have now concluded that, for some reason, I now need to recalibrate the compass before every flight.

    I never needed to do this before when flying in the same field. It would seem that the compass is now "forgetting" its calibrated settings from one day to the next.

    I wonder where the calibration data is stored? (on-board system battery?, capacitor?)

    I will continue trying to solve this.

    I am having the same problem with my altimeter to give a correct reading. It is fixed by doing a compass calibration. The GPS is taking about 5 minutes to be ready to fly on my yuneec Typhoon Plus.

    Have you hooked it up to the GUI to see if you are getting any errors?
