So guys based on some research I did last night - it would appear that with the latest firmware release, DJI has done changes to reduce the range of the CE birds to comply with regulations. According to an email from DJI to a customer, official range has now come in to 300 meters. Whether this is true or not who knows, but they have obviously done something.
So this gives more questions than answers, because according to the documentation, all Phantom's are shipped with FCC config, but then switch to CE depending on the GPS location of the bird. So even with the FCC mod (e.g. Papatitas), perhaps the firmware overrides, which is 1.6.8 seems to be screwing so many people over? Also 1.6.8 for the Phantom 3S is likely the last firmware version to be released (saw that on DJI forums).
In any case I'm still in a bind. 1.5.7 with FCC mod, DJI go app unusable if I wanna actually record video or take pictures. Litchi range is 1/2 that of DJI Go app, but recording works fine. Also had RTH issue with Litchi where it was almost 300m from me and wouldn't RTH.
Getting a bit tired of all this fking around, it's starting to become more trouble than it's worth..
Not Happy!
