[Remove CE limits from DJI products and other fun stuff in DJI Go4]

I just go to mavic firmware 700 for tomorrow fly.

I tested today latest fw 1000 with patched app (4.1.3,  4.1.8, 4.1.9) but FCC not working in real fly- range is the same like on CE version. 

Tomorrow i will fly with this 700 and app 4.1.9 if it will not working then 4.1.3.

On version 4.1.9 , 4.1.8 and 4.1.3 any region windows don't show up on my app. 

But I found 2 tips:

1. very important is to turn ON controller and app first, finaly Mavic last. 

2. in Menu "Image Transmission setting" We can check how many  channels is active 12 or 13, in some cases 14.

Simple turn in Custom Frequency selection, then move "square" to the end right. If You see 2465,5 MHz then this is 12 channels = FCC, if can move it more for bigest frequency like 2476,5MHz or 2481,5MHz then this is NOT FCC.  Probably I'm right. ;)

In my case if I turn ON  Mavic first then  app it will go to CE and have  13 channels, then I must turn  OFF and again ON mavic and app back to 12 channels. 

Waiting for range test from You.

On Mavic  with firmware from 4.1.9  

-  4.1.9 FCC patched I NOT see any longer range :(

- 4.1.3 Apk after change to US (by app menu) I see about 30% extra range.

Soon I will test 4.1.8 and 4.1.5

-----------------------------

It can be by updated firmware in Mavic and controller from 4.1.9 ?

How much Your range was change on FCC ?
