Thank you for your reply.
Well, out of impatience, I decided to take the risk and have just tried it. Surprisingly, it seems to be working well with the
mini 2 SE too, except for one detail - If I want the drone on FCC mode, I have to use the patch every time I switch the drone on. After switching off, the next time I switch it on it goes back to CE mode.
This is something I can live with. In fact, it might even be convenient - I will just use FCC mode when I need it.
Nevertheless, I will still have to test it long range, to see how well it works.
