    Rediscovered piece of RC submarine tech

    Was watching one of Bob's video the other day. He shows an endcap for an Arkmodel Type VII with rotary servo output instead of a linear one.

      I'll take rotary over linear all day long. I also like to support the shaft alignment a couple inches away from the seal to keep things from going out of round. The bushing-to-shaft fitment can get sloppy over time.
