Hi guys i just recently changed the receiver in my Vision + because i crashed it. I took it out to test it today and it showed it picked up enough GPS satellites in the APP and everything seemed ok, but the rear flight lights just keep flashing fast amber, it would not flash rapid green to mark the home point or go to slow flashing green after. This means that control signal is lost. I also noticed that one of my front lights isn't working (due to the crash) is this anything to do with it? Are one of the motors out so it's telling it it can't fly? Any help would be very much appreciated, many thanks.
