I got my p3p to finally launch off the top of a parking structure recently, and then it was like it was in atti mode vs. wind. It was like it was flying without gps, but it was still on the P mode. I landed it soon after but noticed the go app gave me some kind of calibration system warning. Does anyone know what it is about parking structures that mess with the phantom's ability to fly? I remember going for a calibration on another parking structure, but It failed since "metal" objects must have been too near.
