Have done some work on the Jenny yacht. Ended up replacing both servos and had to teach myself to solder brass as the sail arm is a simple brass bar with a square section soldered on to make a โTโ. Thereโs a smaller version screwed into the sail servo disc. This means the sail arm can be above the deck and locate into the sail servo through the deck hatch. Hopefully the pics make more sense than the description!
Was a useful exercise in soldering brass, quite happy with the results, now using the new found skills to make A brackets for my BYMS.
Iโm using a 180 degree servo for the sail servo with an extension lead to get the full 180 degrees of rotation, though have throttled the rotation back a bit via a FlySky Tx to stop the sail arm hitting the mast.
This simple arrangement works well as the main sheet length is limited by the shrouds.
Float tested the Jenny today, no leaks.
She does need some new sails, so Iโll have to give sail making a go.
