Here is the prototype of a purely mechanical implementation of the lifting and lowering function of the foil arms on my AC75. The focus was on lightweight construction while avoiding hydraulics due to the possible damage to the water caused by hydraulic oil.
I use the programmable Hacker servos (here a TD-1005S), but any other servo would be possible with slight adjustments. It is important that the servos are waterproof, as the mechanical module is designed as a wetbox. 10kg on 2S are sufficient as you can see.
All mechanical parts are printed from PLA, I will then switch to PETG for use.
The threaded spindle comes from a 3D printer, 8mm diameter and 5mm pitch. The axial forces are transmitted to the housing via two small axial ball bearings. The aluminum frame is milled from a 100x40x3mm rectangular tube.
