After fixing/improving the help-construction for setting up the tower (big thanks to Ricky!) we decided to reduce the height to only 8m, because the second lifting-up testrun showed the forces are unrulable with that construction. The weight of the top (120kg) is too heavy in respect of the lever-arm (14m). We plan to remove one 6m-part of the mast.
