What's that old saying, old R/C submariners never die, they just smell that way? :-)
If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

Matt,
Can you post more information about your ballast system? Photos greatly appreciated.

Certainly. If you're looking for something new or high tech you are going to be sorely disappointed. Its old hat. Its just a simple pump system. I made a system out of components I had on hand. I'll be back home in late September and I put some up for you then on a separate thread so I don't hijack Dave's thread. Sorry about polluting your thread , Dave!

Thanks Matt.

Sorry Dave. :cry:

Dave,

Nice build and paintjob, and fast compared to me, still playing around with the snorkel and scope, you mentioned your splitting system before, do you have some pics from that, you know i use magnets, but there are more ways to skin a cat.

What I did was make up a bulkhead master and mold so I only had to fit it too the hull once.
Then I attached the bulkheads too the starboard side only of the front and rear sections.
I added some brass indexing tabs on the top and bottom seam as well.
Then the port side is screwed to the bulkheads with small 2/56 flat head screws in countersunk holes.
I added a few more screws to the keel and under the sail.
The hull halfs are surprisingly riged when assembled.
Then I assemble the front and rear sections with one screw on the top and one on the bottom.
They are held riged by two 1/2" Lexan tubes running between the front and rear bulkheads.
Everything comes apart leaving only the four hull parts with the 5 bulkheads attached to the one side.
I can have the boat stripped down to a pile of parts in under 4 minutes.
I only really have to split the front and rear half's to charge the battery though.
I can turn the RC on and off through one of the ballast tank vents.
The sail is held on by a a big threaded standoff that actually is the mount for the scope too.
My safety rope and stanions hold down the deck sections.
It's nothing real fancy like your build but it works.

I do hope this sub is going to be at the Sub Regatta. You could come too if you want to.
Camera at the ready.

I had a chance to look at Big Dave's Type XXIII in person at the SubRegatta and let me tell you, I was impressed. It's sad that competition is no longer a part of SubRegatta but if there was a trophy for engineering, my vote would certainly go to Dave for this boat. Excellent job, Dave!

Skip,

FYI, it appears that the competition may return for next year along with a new navigation course, which is most welcome news!

My very best to you! It is great to see you at the events. I wish I could have been there! :cry:

Yes. the very year that I bring a sub that can turn in its own length,the SRV II, there's no navigation course. I was crushed, I tell you, crushed.
Oh well, wait til next year.

Matt,
I'm dying to know, how did Big Dave's Type XXIII perform at the regatta?
