I Hey everybody. I have an emergency. I am on a shoot with several issues. 1. No video image from camera is being displayed on iPads. 2. LOUD buzzing noise in cone. 3. Landing gear will not lower or raise. Landing gear is stuck in Landing mode and will not raise for flight. Also, I can tell I1 to go to travel mode and blue tail light will be active, but landing gear will not be lowered for travel mode. Any ideas how to solve issues while on production location?
