I'm getting a lost signal when my p3a is flying no matter the height, distance, location, in motion or in hover. I'll fly for about 10 minutes all bars at full and it starts first with the rc signal bars going up and down then in and out with all other bars at full for about 30 seconds to a minute and then all signals go out at once. My p3a goes into RTH lands and then I get all signals back at once. Take back off and it happens over and over again this is what I get. It wasn't doing this before does anyone know what is going on?
