Guys my love for all things flying has taken me to where I have outgrown my p3 standard. It was a great bird to learn on but I need the distance of lightbridge now. So here is where I am at. I can pick up any of those three. Which would you get based on best bang for the buck? I already have two batteries for a three and the gimbal protector and also carbon props. I would sell my standard at a good deal to someone on here. So, I need your wise advice. p3 advance, pro or the p4. Thanks! Also the picture quality is kind of important but not everything to me. The p3 standard takes some stunning photos. But that is not what I am basing my choice on.
