There is a large app-modding scene too.
You can download the source code for the DJI GO3 and GO4 apps, change whatever you like (eg, remove NFZs, enable FCC, etc) and roll your own app to suit your exact requirements.
The DJI Fly app source code isn’t out in the wild yet, so your only options there are to use modded certificates (ala Drone Hacks) or a third party modded app (ala Drone Tweaks).
If you’re thinking of buying any of these one-click apps such as NLD, Drone Hacks, Drone Tweaks, then check out the Members Only category, we have exclusive GADC member discounts in place for most of them.
These discounts are available to GADC Full Members only.
