Drone Tweaks
Modified DJI Fly for phones. FCC and 5.8 GHz turn on automatically. Keep the stock app installed.
FCCmod
Fly farther. Stay connected.
FCC mode and 5.8 GHz for DJI drones — where CE limits hold you back.
Why FCC mode
CE caps transmit power at 25 mW. FCC allows up to 400 mW — several kilometers instead of a few hundred meters.
CE · 25 mW
Short range in cities. Link drops at 100–300 m.
FCC · 400 mW
Stable link over kilometers. More reliable connection.
DJI controllers
Dedicated unlock for DJI remotes. Pick the one that matches your controller.
DJI RC 2
FCC mode, 5.8 GHz, and altitude unlock for the newer RC 2 remote.
DJI RC Pro 2
Dedicated unlock for RC Pro 2 with stronger signal and longer range.
DJI RC
Powerful FCC signal, longer range, and a stable high-quality link.
Drone Tweaks
Phone app for mobile controllers.

About FCC mode on DJI drones
DJI drones operate in different power modes: CE and FCC. In CE mode, transmit power is limited to about 25 mW. In FCC mode it can reach around 400 mW. That is why drones in FCC mode usually keep a much more stable link and fly farther.
In cities, CE mode can lose the connection as early as 100–300 meters after takeoff. With FCC mode, usable range is often measured in kilometers instead of a few hundred meters.
DJI drones also switch between 2.4 GHz and 5.8 GHz. 2.4 GHz is often better outdoors, while 5.8 GHz can work better in urban environments with strong Wi-Fi interference. In many countries outside the US and Canada, DJI defaults to CE mode and 2.4 GHz.
FCC mod or hack
An FCC mod unlocks higher transmit power and, where available, the 5.8 GHz frequency. For phone-based controllers, this is usually done with a modified DJI Fly app such as Drone Tweaks. For built-in controllers like DJI RC, RC 2, and RC Pro 2, the unlock is installed on the remote itself.
The app installs next to the stock DJI Fly app. There is no need to uninstall the original software. FCC mode and 5.8 GHz activate automatically at startup. A separate certificate is not required for Drone Tweaks — it is already included.
Phone app or RC unlock?
If you fly with a phone attached to a controller, Drone Tweaks is the simple path. If you use DJI RC, RC 2, or RC Pro 2, choose the matching remote unlock instead. In both cases the goal is the same: a stronger FCC signal, longer range, and a more reliable connection.
