And again some progress. The hydroplanes and the stabilization fins are installed. The mechanics for the rear hydroplanes is somewhat complicated, as the hydroplanes are too close to the pressure tight compartment to be directly connected to the push rods and the propeller axis prohibit a straight hydroplane axis. So everything is controlled via a second axis....the connection for the rudder is installed as well:
Allot of work as well, the water inlets in the upper hull. I didn't just want to file some, so I fabricated frames from pu-resin and glued them into slits in the upper hull, filled everything and sanded it down flush to the hull's outer surface.
Similar business are the snorkel housings. Got the rapid prototyped and then glued them to the underside of the deck. After that the open parts in the deck were milled and filed away. Front:
Same thing from the inside - rear:
And again the water inlet frames in detail:
