I've had the i1 for about 6 weeks. iPad Air 2 for slave (cam operator) and iPad mini 2 for pilot. I have had video transmission signal problems with the slave/Air2 since day one, but initially it was only occasional. Now it's persistent and makes the 2nd downlink almost useless. Constant signal loss (black screen and notification) at close range. I can't even stream a saved vid file without interruption with the controller directly next to the copter. Airplane mode on, all programs closed, hardware acceleration checked on, all background processes disabled, ribbon connectors checked, gold contacts cleaned. What gives? Faulty lightbridge?
