i bought a used fliteboard pro V1. The first step was to construct a adapter plate.
For this I milled a 15 mm thick aluminum plate. The outsides are milled down to 7mm. In the underside, the cables are sealed in a duct and routed through the panel. The mast foot is screwed into the aluminum plate with M6 screws but not drilled through so that no water can penetrate.
The board is currently under construction and not ready yet. So I can’t say yet if everything will work in the end.
