Bubul : Plans!
I can't remember how many times I've been asked for the plans of my RC submarine... But the trick is, I never made any plans! But I finally decided to make some, so after some efforts with a caliper on one hand, andSketchup in the other, here is the result!(and it was a good challenge for my Sketchup skills!
)The synthetic plan is available as pictures below, you can as well download it as PDF, or even download the complete Sketchup model, everything is designed down to the 1/10th of millimeter!
Edit 2014/03/21 : Bonus, an interactive 3D view!

The 50's in the US... or not?
Not only these were taken nowadays, but moreover, they actually are 1/24th scale models!
They're made by Michael Paul Smith, whose working process you can see here. Quite impressive... More pictures to see on his Flickr and SmugMug sets.

Pierre Scerri
I'm surfing the Internet for 10 years... Being fond of R/C modeling, and more generally of D.I.Y stuff, I've seen web pages about more or less skilled handymen. Sometimes, you even find a higly skilled one, doing great job...
But, here, this is nothing but exceptional.
This no more a hobby or a passion (unless in the etymological sense) : Pierre Scerri builds 1/3 scaled replicas of Sport-Proto Ferrari.
But this is not only about building nice models... No, he is building EVERYTHING in 1/3 scale, and everything is functional! Obviously the engine (flat 12 cylinders), but the gearbox, headlights, gauges!
He didn't konw where to find the corresponding tires : easy, he learned the building process of real ones and creates a mould!
Headlight? He learned about glass working and make his owns...
He builds absolutely everything : the crankshaft, the 4 camshafts, the injection system, radiators, engine case, cylinders heads...
Do not miss the videos...
12 years of work were necessary to make the Ferrari 312PB 1978, from which 3 years only to draw the plans and schemas. Such a level of perfection is almost scary to me...
And you know what? This guy is French! Sorry, you american visitor, we did better than your scaled V8...
Congratulations M.Scerri, it will be highly difficult to do better than you now. I still can't even believe it myself...

- Thanks to Jean-Paul CHALET, from the Miniflotte Rhone-Alpes Club, for inventing the camping gaz-cans submarine (sorry folks, t'wasn't my idea!)
- Thanks Jérôme for the pictures...
- Thanks Nicolas for the machined parts...

Mechanics
Nicolas "Always Higher" Petit machined for me the little parts needed for the motors orientation mechanism ; he as well found the matching 'U' seals...

Presentation
I've started building this model in 1994, 13 years ago! It has navigated a lot, in the Sciences University ponds, in R/C meetings, in swimming pools, in rivers... And it still does!
The beast is 25cm long. The two half-hulls were made from camping-gaz cans.
The front transparent bulb has been hacked out of a Kinder Rabbit (you know, the one stuffed with little chocolate eggs for Easter!)
The interior of this bulb has been decorated with some die-cast plastic hacked stuff : bucket seat from a BMW, Alouette II helicopter dashboard, stickers from Mirage...
For the static dive, it uses a ballast : it's a small plastic accordion-shaped part (just like the ones on kids bikes, acting as a horn!) on which a servo pushes. It can suck up to 8 grams of water from outside, making the submarine heavier... And it goes up, or down, depending on its relative weight...
Benefits: way easier to build on such a small scale model. Without specific tools (lathe and mill), there's no way to make them water-tight.
Drawbacks : they wear faster, and I've got to change them every year. 4 welds and 7 euros later, and here we go again!
To rotate the submarine, I reverse one motor, so the machine turns like a tank!
The (functional) headlights were hacked from disposable cameras flashes...
The little tube linking the bulb to the hull allows pressuring the bulb ("better bubbles out than water in", this is the rule!). Indeed, all the water-tight elements are put under slight pressure by blowing into the bike tire valve (the little chromed thing on top in front of the antenna)...
The LEDs on the fins are functional as well, they flash when the radio is turned on.
And to turn it on, you can see right behind the bulb, on the front half-hull, an 'excrescence', which contains an ILS lamp (there's another one on the other side of the hull).
So, to switch it on, I just have to approach a magnet on the right side, and to switch off, I approach the magnet on the left side.
Such a system is a must-have, in order not to have to disassemble the whole thing to switch the radio on/off...
The fins are made out of epoxy (the one used for PCBs). I perchlorate-engraved them on their inner face to connect the LEDs...
The skates are made out of plumbing copper tubes. The end spheres at the end were made out of bondo (Synthofer, free ad!), molded in a plaster mold (this later made using a marble... Never throw away your child toys!). The rear half-sphere can be removed, by unscrewing it, thanks to a rubber seal.

Diving :
My model dives both statically and dynamically.For the static dive, it uses a ballast : it's a small plastic accordion-shaped part (just like the ones on kids bikes, acting as a horn!) on which a servo pushes. It can suck up to 8 grams of water from outside, making the submarine heavier... And it goes up, or down, depending on its relative weight...
Motors :
As you can see on the following pictures, the motors run freely in water!Benefits: way easier to build on such a small scale model. Without specific tools (lathe and mill), there's no way to make them water-tight.
Drawbacks : they wear faster, and I've got to change them every year. 4 welds and 7 euros later, and here we go again!
