Domino60, what you may not realize since you're not in the US is that relations between the RC community and the government are very tense right now. Autonomous flight and drones are making the news regularly now, and usually in very bad ways. The FAA is considering some heavy regulations that would significantly change the way RC has traditionally been enjoyed because of that. So whenever we see someone talking about long range flight, modifying radio gear, drones, etc, we get suspicious. You were being fairly secretive about what you were up to in the first few posts, which adds to the suspicion. None of that is your fault, but you did breach a sensitive topic in the American RC community. Now that we understand what you are doing, I think you'll find everyone is much friendlier. But like I said earlier, the things you want to know are rarely done by traditional aeromodelers.
