I recently got a phone standard from a friend that had the compass plug torn off. I ordered a new motherboard from rc recyclers complete with a new flight controller. After installation, I went to try it out ,and it said " warming up". That never happened before with the old board. Then I tried recording. No luck. Also no photos. The camera works ,but no recording. Also when i go to menu, it says 4k. What is going on? My friend says I need to put the old flight controller back in. But I hate to do anything that may mess up the new board. HELP!!!!!!!
