My P2V+v3 sometimes needs a bit of a kick when going back to GPS mode from Atti mode. Sometimes I try to get an idea of wind strength by letting it drift in Atti mode, then I switch back to GPS mode. Just occasionally, when I flip S1 back up, the Phantom continues to drift. So I toggle Atti and GPS again and it stops drifting. I'm not talking great distance here, the couple of times I've seen it, the Phantom was maybe 50' to 100' away and 80' to 100' high. My antenna is usually 90 degrees to the controller, with the controller tilted, which means it's usually at an optimal angle to the Phantom. Has anyone else noticed this?
