Hi, I'm struggling with n RC Signal Lost problem. I have the p3 standard and it's updated to v1.7..... something. I can fly it for about a 50m radius then it compeletly loses RC signal. I have read online that relinking the RC could solve the problem. I tried this but It didn't work. Next I tried downgrading the firmware but when I hold that "graduation hat" for a few seconds and it opens the page where it shows you the options of previous versions to download, it says in red letters that it is unable to find downgrade options. I've tried this on my iphone, ipad aswell as samsung tablet and they all say the same thing. What other options do I have ? Please help
