With all the current reports of crazy flight behaviour and control issues I'm finding myself having very little trust in P-GPS mode as every report seems to be in that mode of flight. The thing that worries me about ATTI though is takeoff and landing in wind as until airborne it's very difficult to gauge the effect of the wind. I wonder why DJI have limited the use of the Visual Positioning System to P-OPTI which is only available in P mode when not enough Satellites can be attainted for P-GPS. it would seem to me that having the ability to use the VPS in ATTI mode as well could be really useful. I do understand that there could be a tricky transition as the VPS moves out of range and wind starts to have more effect but that would just be another thing to learn. Even if VPS was only engaged as the landing gear came down it could be a useful tool. Or am I missing something?
