    1/72 USS Seawolf SSN21

    Not really a build thread more of a lookee what I have gotten hold of!!!! I had my I eye on this beast back in November when I transported a stack of RC ships and Subs for Slats from Sydney to Adelaide during his big move, I said to him then if he ever considered parting with it I had first DIBS!! Couple of months go by and Slats says to me "U interested in the Seawolf still??" ME "F#$% yeah!!"

    Currently just doing some test running on the surface of our local pond..the water is so dark the sub vanishes before the sail is full submerged.....!! Still need to build a new WTc for it out of the big box spares Slats has given me. At the moment the its running a Hybrid WTC, the cylinder is from the Seawolf with the endcaps off my USS Shark's subdriver, as I did not have a spare ESC to build a new drive module end. Going to get a 11.1v lipo 5000mAh for it as the7.2v pack does not give the airpump enough juice.

    Here are a few pics on the bench (and with USS Shark alongside to show the size of a modern boat compared to a1st Gen boat!) and some from our recent TF72 running day

    Cheers Bruce

      That looks so nice on the water! Wonderful photos too!
      If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

            yeah they look to be 3D printed I will ask Slats if they came with hull, they work sweetly! You will notice something I like to do is put a small cut of 3mm blue silicon fuel hose on the connectors it helps them stay perfectly aligned. I tried this after a few probs on the Skipjack with connectors somehow coming off underway!!

            Its a great boat to drive looking fwd to getting him in a decent clear lake!!

            Building a new test tank at the moment so I can do trimming, dive and ballast test's on various ships and subs (both mine and Slats). The new tank will be reconfigurable so it can be either 2.18m long X 550mm wide and 500mm deep or 4.36m (ish)long X 550mm x 250mm deep for some of my longer ships like my LHA which will need to go in the test tank when I get stuck in to figuring out the well deck ballasting system....not something I want to test out on the boat pond!!

              I keep looking at your photos. They are eye candy for sure. I have not been out for a couple of weeks to run my subs and this just makes me miss it even more. Thank you for posting and look forward to updates!

                Thx mate, We are lucky here in Adelaide we have very good people running the (Covid) situation. Our merry band of 1/72 manics have been able to get back to our monthly running days, although we missed about 4 months of the best weather due to lock down rules.

                Out in the workshop I have cut up some 12mm ply sheet (donated by a clubmate who was moving to a smaller place) and knocked out a new Test tank. This one is modular so I can set it up 3 different ways!

                1/ Is 2.18m X 60cm X25cm deep for small surface ship testing.

                2/ Is 4.36m X60cm X25cm for larger ships (primarily to do the welldeck ballast trials on LHA2 in a controlled space)

                3/ Is 2.18m X 50cm X50cm for sub ballasting and dive testing.

                All it cost was some time cleaning out my mates ply collection and $4 for some wood screws!! Just need to buy a tarp for the liner ($22) and some cheap paint to seal the ply.

                Cheers Bruce

                  I'm amazed that it's strong enough to hold that much water... I used cinder blocks, just one one layer high, set on a "picnic" table I made a few years ago, and that thing settled considerably once I got it full. It is a very handy thing to have, especially when you don't have a pool, and your craft have outgrown the tub...

                    Yeah if it starts to bow out I will brace it with some stacks of wheels!! We have plenty lying about... I did same with my first test tank back when I was ballasting CGN9

                    this tank ended up leaking like a sieve!! it was very dodgy. At full power LB could dump half the contents of the tank over the back end.....then she would start cavitating and test complete!!

                      Yesterday was nice and Sunny (unexpectedly warm 23C). So I set up the mk2 test tank in backyard and set about filling it up, ended up bracing middle with some wheels as it was bowing out as predicted!! Once full I got SEAWOLF out for a test of the test tank...had a play for a bit running the beast just at periscope depth at full power....with the bow against end of the tank the shrouded thruster actually starts to create small whirlpool vortex above the shroud eventually it sucks air down!! Fun to watch....obviously when its moving this would not occur. Here are some pix!!
