I’ll 2nd that!Personal opinion, if every thing works and you are not forced to update then don't.
We’ve seen reported here too many times that someone put away their P3P when it was working perfectly, and then X months/years later they dusted it off again only to find it no longer works. Often it’s no image transmission. At the very least, test it for functionality before introducing any variables such as different firmware. Also, I’d be 100% sure that I knew which versions of FW are currently on both the AC and the RC before changing anything. That applies at any time in fact.Hi, I have a pro 3 and have not flown it for about a year, before I do should I update the firmware ?
