    Talk about small

    Not sure some of this could be used in our hobby, but it is fascinating. 1.7gram servos are not new, however the flat super tiny “servo” is. It looks like it is more of a bang-bang type or all the way one direction or the other. https://www.minimumrc.com
    If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

    They look like magnetic actuators to me, insufficient torque to pull the skin off a rice pudding, not much use for subs (and barely adequate for aeroplanes).

      no need to make them waterproof.
      Make it simple, make strong, make it work!

        If you modulated the transmitted signal to a variable pulse length (much slower than servo signal pulse rate) -- ala 'galloping ghost' r/c system of pre-historic times -- these little actuators will produce a chatter whose direction and net amount of motion is proportional to stick position. The mini-mini r/c flyers use these things in this fashion.

That was a big step ahead for me as I was weaned on carrier-only, rubber driven escapement, rudder only r/c control flying when I first got into the game. Thanks for the find on that document Andy. That was super-science stuff in my day.
