Rudder jackscrew and servo for it

Place for general submarine conversation

Postby TK-7642 » Fri Jun 20, 2003 12:16 pm

Anybody know where I can get a servo and a small jackscrew for inside my tailfin ( fin about 1/4 inch width or less for Goff Nautilus) to operate the rudder? I don't want to have an outer bell crank. I will put the servo in the watertight compartment to turn the remote jackscrew via a shaft, like T-tail jets have. Thanks.

...you could make one from a length of threaded rod and a nut.

The nut would be soldered to the rudder control arm such that the threaded rod would be angled through the skeg (or fixed dive plane). Then you'd just need to rotate the threaded rod to effect rudder motion.
