Hey Andy-
beautiful model of a pretty complex design...who's the master pattern maker?

Chap called Andy Cox. Don't think he is a member of any sub organisation, and he isn't online as far as I'm aware.

He is a professional pattern/model maker, which explains the very high standard of workmanship.

There was talk of a kit at some point, but the price was, unsurprisingly, rather high. Around £2000 I think, roughly $3500 dollars at the present exchange rate....ouch!

what are those rudder things for and why do they move in and out?

I'm pretty sure the Seaquest was based on a whale, judging by the shape.

The tail (rudders) at the back, act as a hydrodynamically flowed exit to the four pump jets located within. When a strong burst of power is required, they open out and the jets have an unhindered path to push as much wet stuff as possible.

It's probably highly inefficient in the real world, but then Sci-fi boats only have to look the part, don't they?!

A whale? Take a look again.

That sucker's a squid 100% through and through. The front is arrowheaded like the squid, and the "fins" aren't fins, they're TENTACLES!

The thought that I had when considering an RC Seaquest was to have those tentacles act as rudders and dive planes. Push out the right tentacle, the drag causes the sub to go right. Want to go up? Lever out the top tentacle to force the aft end down... I think for even greater performance you could array them in the X-tail configuration rather than the cruciform one and use a mixer for even better performance.

Just my two cents worth.

Yeppers,
Speilberg was,and still is,a big fan of 20,000 Leagues Under the Sea,so his Bio-Organism skinned ship is based on a giant squid. It even used jets of water for propulsion. There are four primary nozzels and 4 secondary ones. The rear fins do actually move inward and outward to provide the turning capability,though water jet side thrusters expediate the process. The fins possess some sort of ventral vanes as well..really like the ship .The primary function of these "rudders" seems to be for at rest and for cruising to keep the Seaquest from going fast,they are "branched" or extended out...when the are "back" or in,this is for going max speed ,kind of along the lines of the Torando or F-14 Tomcat wings idea.......... started a cad drawing years back as i was aquiring reference on it..still am...............have most views finished now....but an ongoing process
William

Could they be for vectored thrust? Also they seem to have internal vanes like a v2 missle.

Those Pictures were incredible. After looking at them, I think that it would be a very difficult project to make this model type truly R/C. I find it interesting that it is placed next to a Seaview model which is a very difficult Sub to make in the R/C mode. I am referring to a smaller scale of seaview here.

The first question is how would you propel this sub. If you do incorporate pump jets, they have to supply enough water to move the sub. This means placing some good sized holes in the hull itself to feed such a pump jet. The seaview I made, incorporates pumpjets. You have to cut out many water fill holes to feed enough water into the pump jets to provide adequate propulsion.

The other question would be how to direct the ship above and below the water? The pics show how the tail opens up. I don't think that you really could use those surfaces only for directional attitude. I don't think that there is enough surface area to make a difference.

I think that the only possible way of propelling such a sub ( and keep it looking close to the original) would be possibly making a special type of WTC that would look like a cross at the end. You could have three motors, one port, one starboard, and one aft. The two on the sides would not be as powerful as the one in the rear. The two on the sides could direct the boat starboard and port. The one in the rear could incorporate a similar configuration as the seaviews pumpjet that dave merriman did on the deboer seaview, with the stern planes extending from the rear propulsor tube. This is only one idea that comes from a newbie. If someone were to get this sub operational, my hat is off to them, and my utmost respect.

Making the Seaquest work?

A challenging prospect indeed.

As already mentioned, vectored thrust from the water jets would be the answer to pitch and rudder control.

Additional jets could be hidden amongst the plethora of vents in the hull design, for extreme manoeuvres (definitely a good idea on a boat this size!).

As Bob said, the tail pieces could be used to act as rudders and vanes, but better in addition to the vectored thrust- the two would make a good combination.

Regarding feeding the thrusters, I think that is self explanitory from the pictures- it will suck in through the vents moulded into the hull.

Whether that is sufficient remains to be seen.

Cheers

Andy

A few bilge pumps connected by hose might propel this ship.
The bilge pump intakes are not that large and and would form an intersesting orfice on the surface of this exotic looking vessel.
