Sorry, I have had no chance to do it today. Will try on Mon.

I will measure the bird transmition power with and without FCC mod tomorrow. Will share the results.

I am sure that DJI reps have no chance to make the poker face and just ignore the facts of firmware and app hacks. I think they are already on the way to close all the abilities to modify software and firmware, but it looks difficult to do shortly. Suppose, it is possible to update the DJI GO to send the current system config to DJI server and check for unauthorised changes. But what will do DJI with such customers, I do not even know. I guess the unauthorized NFZ unlock is the great headache for DJI.

As far as I see, the FCC mod just allow you to use the FCC settigs for transmitters, instead of CE. Both of the modes (CE and FCC) are standard for the any DJI copter and should not cause any overheat. In stock App and firmware FCC could be disabled based on the GPS informaton. To be sure that your device works in FCC mode just measure the RC and drone's transmition power. Will do such measurments tomorrow.
