It's interesting how personal experiences can jade a person's opinion. Although my P4 never crashed and did nothing strange, the range with the stock controller, even with Windsurfer, was sub par, compared to my P3P. I had to buy an Inspire controller to achieve decent and reliable flight range with my P4, similar to my P3P, about 3 miles in rural areas.
My
P4P flies incredibly far, over 4 miles with Windsurfer, and to heights you wouldn't believe when climbing mountains. And then there's the 1" sensor camera, it's awesome. My
P4P is absolutely incredible.
