I have been kind of debating which platform to get next. I have been using a Phantom v1 up until now. I would mainly be using it for AP and FPV. A lot of folks seem to be going with the F550, but the F450 gets significantly better flight time, which would be important to me. So what would be the advantage to going with a 550 instead of a 450? Supposedly the 550 is more stable in the air, especially in windy conditions, and can carry more payload, but the 450 seems to do pretty well in those regards as well it seems. Also, the 450 is more compact and would lend itself to transporting more efficiently in my opinion. So, is there any compelling reason to get the 550 over the 450 for that use? Thanks.
