My dear friends, I am trying to put the Liberty Walk’s massive wing on my 12c and it seems that I have to disable the function of the factory wing lift in order that there is no error sign about the air brake failure. Does anybody happen to know how to disable the factory wing lift for 12c/650S? I called the local dealer and got the answer that there is no way for them to disable it using their system... Thanks a lot for any help!!!
