Hi, I use a second controller and tablet for the camera. The problem I have is I often lose the picture. The picture on the pilot controller is always perfect. I've tried moving the controllers away from each other but makes no differance. Any advice would be greatly appreciated.
Thank you,
Gary   

What kind of tablet are you using? Try using a different tablet or a phone and see if the quality gets any better. We have found that picture quality varies depending on the device being used.

I'm using a ipad mini on both controllers, the pilot one works fine its the camera controller gives trouble.

Nothing to do with the device - Google "32 Channel Hack" for the answer.
