Hello, to all who were answering! Yes, I have read the documentation,- but it is for me sometimes not so easy, because it is in english and sometimes I do not understand the full sense! By looking the video I have seen, that you have to pull a lever to unlock the controls,- somewhere near the co-pilot seat. I`ll try. Overall, - it need to be a long time, to get familiar with this aircraft as I see.- What I am missing is a tutorial for a whole flight... (Schade!) Nevertheless, Thanks a Lot,- Best Regards, Siegfried
