I have tried to be patient with you over my last few posts. I have asked you what you mean by 'things done differently in the U.K.', to which you have avoided answering satisfactorily. I have answered your question about 'finding a power source that can last a lot longer than the batteries that comes with this thing ' by saying that you won't find any battery that will give you more than a minute or so in the air better than the Yuneec battery.
You say that 'you no longer have to ask me about all this other stuff because I'm not interested in that', but you have made a claim that you were able to drastically increase the signal output of the ST16 by doing something in one of the menus of the ST16 so that your aircraft could fly 7 miles out but refuse to explain what it was you did to get that enhanced performance (in truth you can't because there is no way to do it). I have offered to help you but you won't give us any information that will help us to help you. You won't post telemetry and not much of what you have said makes sense...and I'm not talking about your poor English.
I give up.
