Hi guys, I have a P3s, I bought it and immediately joined this forum, which was July 16. However due to family problems and life in general getting in the way I have only just started flying. Its great and I can see the pleasure of flying. My question is, the app says I need to upgrade my firmware. It is a 3s, life in Quads has moved on, so my question is this, should I update or leave as is.
