vectored nozzels

Yes Kerry, I did vectored nozzels in the big and little fs-1 and some work on Seaview as well , my nozzels were from a ball valve with ball link connectors set at 90 degrees x 4 points , 2 driven and 2 as guides in slots
On one version I used semi circles as dive planes but need little throw too redirect the flow , I found full throw as pointed out did choke off flow so 5-10 degrees was good.
You will never get a rudder / dive plane responce like Big Daves sushi boat but that is a Tuna of a different color !
The ball nozzels I first sandwiched between 2 concaved plates too allow full rotary movement and yet captured so there was no drift off the center axis.
As I tell my cat " There is more than one way too skin you , but lets try the first method if you don't get your hairy ass off my keyboard!"
I love fly in your face ,nonconformist ,give it a go ,outside the box R &D stuff if even only based on hair brained ideas !! Some times they do work out and at worst they don't and you learn somthing in the process.
Bottom line you are "Doing"

Here's a link to a good pump.

http://cgi.ebay.co.uk/REICH-14L-SUBMERSIBLE-WATER-PUMP-caravan-motorhome-boat_W0QQitemZ170283845594QQcmdZViewItemQQptZUK_Campervan_Caravan_Accessories?hash=item27a5b547da

Runs on 12 volts DC, small(ish) and 14 litres per minute flow, so should empty your tank in about 12-17 seconds allowing for friction in the lines and valves etc. Use with a vented tank, and incorporate a trim tank 10-15% of your main ballast(piston tank or smaller water pump system) for trimming to neutral buoyancy.

So your main ballast tank would be 2.5-2.7 litres and your trim tank 300-500ml.

Because the main tank doesn't have to withstand pressure, it can be made any shape you like, although a cylindrical shape is best in the Seaview.

You will also need to make a large valve controlled by the servo to allow water in at the bottom of the tank.

The pump could be mounted inside the tank, as they're sealed and waterproof.

Hello subculture.Thanks for the heads up on the ballast pumps,Iwill check them out on the net as I am on night shift tommorow.Cummeron 31 mentioned that I had a thought to use a twin bellow system.This was all built and tested on the bench and worked well.There was only one problem.The two centrall water tight cylinders they were attached to would not fit back into the boat when built up.So that was the end of that Idea.I still have all the parts for this system so it might find its way into a type VII that I intend to be a test vessel for the Seaview.s systems. On the subject of vectored nozzles .You could use them as extra rudders if you could over come the connection problems.But personnally I dont think you would get much more control over using the three rudders that make the Seaviews back end look as it does.I will post more in the future.

Too bad the CultTVman site dropped my SEAVIEW how-to article. They still offer the DVD of the assembly I did on the smaller DeBoer model though.

Hi Guys,I was told about this form from Kerry a while back.I tried to get on it at that time but had problems getting in.My wife helped me tonight.and I made it.All I can say to you guys is wow!!! You guys are going to make this 80 inch monster work! I have mine sitting in my shop,it has been painted and thats is how far I have gotten.Now that I see you guys finishing you seaviews,Its makes me want to finish mine. Right now Im building a 1/72 ssn 21 seawolf to sell next spring.When I finish that I want to get back on the Seaview.There is loads of imformation on this form to help out everybody.Anyway I just wanted to say Hi to you builders Keep up the great work,and I will be watching this site.

By way of introduction, Dennis DeBoer IS the SEAVIEW man of the r/c world -- it's his GRP hull kits, mostly, that you see within the pages of magazines and photos posted to the net.

Dennis is an excellent model builder -- one of the best!

Yeah, we got to get a proper pump-jet worked out for your big SEAVIEW one of these days.

Welcome aboard.

David,

Hi David, Thank you very much on the kind words about my models,and the warm welcome to this forum. I plan on learning a lot from this forum and your great model building!Like I always said, the modeling people are the greats people to know,I will be checking in ever so often,on building updates, and new products.Untell later,thanks, Dennis.

Nice to see you Dennis! Post lots of pictures of the 80 inch....
Somehow seeing them induces me to want to spend money on one.
Somehow I'm not resisting much...

seaview80"

hi guys
hi dennis welcom !!
if the master of all things submarines david took a moebius seaview kit
and made it do great things with his wtc system why will it not
work with this big 80"hull?? reverse seem to be issue but if cheater holes in the bottom of the thruster tubes are used to vent the water out
to go backwards out the lower vents thease vents can be removed to
run when. on display the vents with magnets on them can be put in
place and no one would know any deffrents am i thinking wrong ??
i think david system can work

The articale in scale ships many years ago with Dennis's Seaview is what got me interested in r/c subs

Hello Seaview.In answer to your question about the engine vents.They are needed in forward and rear propulsion.In tests done on my own moster of the deep I found that the gill slits helped in both directions .In forward motion the vents guided the water flow into the props aiding propulsion.In reverse I found that with out the gils being there and just a large hole the Seaview tended to move left or right when reverse was applied,but with the gills in place the water flow was dircted down both sides of the hull and the sub comes to a nice straight stop.The down side is that you do need to make sure that the gills are fillied and held in place well.I will try to post some photos of this soon.

Kerry the part numbers are 12385806 or 12470911. Check the prices there and let me know my GM prices are $70.70 and $85.60 plus tax. These are both reversable air pumps with relays and wired up to a connector .I will post
you a picture when I get home. Either should work great for a ballast tank pump or a surface pump as we where talking about.

Jim,
Thanks very much for this info. I will check it out.
Next week I hope to post pics of my custom ballast tank now under construction.
