What would change in the aerodynamics between the p4 and
p4p, if I understand the question? Unless I'm just mistaken because I don't own any p4 product yet (only p3) I think you'd see no difference between the p4 and
p4p in terms of wind performance. I think for the conditions you describe it would be wise to seriously consider the
I2 if you really need to fly at those times. If saving at least 3,600 bucks and just skipping severely windy days is an option, just skip flying. I'm mostly faced with the same choice because of handling windy conditions, only for me just skipping the flight would not always be the better option if there's a craft that can handle it, because the flight would at times be a critical commercial flight. And therein lies the tough choice because the phantom
p4p craft is not up to the power needed, but camera and flight time is a huge plus. In the end though, when it comes to handling windy conditions more capably there's no comparison - the
I2 will power through more capably than a phantom ever could.
However you mentioned a small business and if the camera is a big deal, you'll see better quality in that department with the
p4p. If a p4 was a choice for anyone, I can't see why anything less than the
p4p would be considered in terms of pq.
