Hi. I am almost ready to pull the trigger for a new Vision Plus and let my 3 months old regular vision to my son. I want to know if the newest vision + require the mod for the gps signal to not drop with camera vids, or this problem was already addressed by DJI. Also want to know in general terms about he reliability of the plus vs the non plus. My non plus has over 50 no issues flights, so I find it very reliable. Thanks.
