Glen I would advise going to 3600 lb axels if you are going to
use two of em. In past experience
the 2000 ones are a little short. You also need to be able and
put tires on that will support the
load.

3300 pounds. Build the trailer for more. 2000#
rated per axle at least. And install brakes. Very handy, those brakes.

30 knots? Shades of
Cliff Redus!!!
Maybe there was some amount of weather vane stuff, but with 8 tons
and up of submarine, it didn't seem to have much of an effect. If it did,
we just compensated with that same rudder.
I still like the electric linear operator for this. The ones I've
seen look like hydraulic cylinders with a rod coming out one end through a
seal. Have you seen those? Inside is an electric motor and a worm gear.
Extension/retraction has some sort of indicator, too (as an option). I
wonder what those puppies cost?

Hi Vance. I understand how a big rudder helps with steering, whether
the prop is turning or not, as long as there's some travel. With a big
rudder, does that make the sub turn into the current if there is some
cross current ? You know, like a weather vane.
Dean's sub has a big rudder and I was wondering how it would affect
the sub's travel.
The big "fin" on the back of my sub may act something like a rudder
in a cross current.
I needed to add the fin because early scale model testing in
moving water produced some "wobbling" and by adding the vertical fin it
stopped. Now, I don't have any means to equate scale model speed in the
pool to real life speed for the full size sub, but the water speed in the
pool was probably a lot faster than this little boat will ever go, so
maybe the fin wasn't really necessary for the expected slow speed the
sub will actually go. If I had to make a wild guess, I'd say the pool
speed was a scaled down 30 knots or so.
