Is anyone having problems with GPS dropping during flight? Until today I've had many great flights with my i1. Today I've flown 4 times and each time I started with full bars on GPS and shortly after getting airborne I'm losing all satellites and the ready to fly bar says "ready to fly no GPS" if I continue to fly the sattlite strength bar will change back and forth from GPS to no gps. Anyone have any ideas? I've got 4 years experience flying Droidworx hex and 3 different phantom models.
