Help! I'm just getting this bird back together. The RC and camera are binded, ST16 shows telemitry but when I push the red button I get no prop start and no lift off. The wifi from the camera connects and shows video. What am I over looking? When I go through and and check the switches on the st16 all controls work as they should. Strange thing is it all worked and flew before I stored it for a month or two.
