My FPV camera image freezes once the P2V is a foot or more above the ground. The camera still records the entire flight, and I can watch it after landing, but FPV is unavailable. Initially I thought the WiFi signal was bad so I purchased and installed a new RE500 WiFi Extender for $99 and then added an auxiliary battery to make sure I wasn't running out of power. It didn't make any difference. Earlier today, I updated Autopilot system and Central Board to v3.00 and V184.108.40.206 respectively, and just now I flashed the FC200 camera to V1.1.19. Still no change. I've even tried pressing the unlabeled button under the FC200 camera. Nothing! (What is the button supposed to do?) I'm out of ideas. Anyone?
