Been trying to get into the GPS calibration with no success. Set up is really basic, Futaba 14M, R6014HS. Set up everything according to manual & program to include all updates. Been flying it for a couple of weeks now to fine tune and every thing checks out except when I go into GPS Attitude, red flashing light. Yes I know the cause of the red flashing light is because I can't get into GPS Calibration mode. Been flipping switch according to manual and it's not happening. I just can't get it to turn blue so I can turn around and get it to turn green, followed by the 3 second white flashes. Did I miss something during the set up?
