Not sure if it’s fixed it entirely or not. Sometimes it difficult to notice if it’s dropping. Unless I never had the issue as bad as others.
Other than that it seems to me that you see the props in video more with this update.

I have had a fair few flights on it and don’t see a drop when stopping like I did before.. Noticed the props in my live feed but not sure if it’s more than before.. I normally only see them when flying in sports mode from one location to another. In P mode don’t see them..

Not done an IMU or compass cal for a long time ( even though I always mention it in firmware update posts 🙂 ) so will do that when I get time and see how it is..

Wiht firmware 1.2.503 installed, AC has problems.

I resolved this dialog notice “No Image Transmission Signal” after reformatting the micro SD card in OS Mac utilities to EX Fat, then repeating in the now functioning AC camera. A OK. I power up & off several times no problem. To day a short test flight. The rig was tested prior to going outdoors. To my shock, new dialog “Aircraft Disconnected”
I’m beaten, The only window available “How To Connect Your Phantom” Stunning work DJI.
