Two possible sources. British Cruisers, Two World Wars and After, by Norman Friedman
British Cruisers of World War Two, Alan Raven and john Roberts.
The first has a profile plan circa 1942 immediately prior to her loss and a photo, same time period, again a profile.
The second has a three photos of her in different time frames, including an aerial circa 1941.
If can can not access these, I can try to scan them and send them to you.

Incredible weathering! The ghouls are amazing😁😁.
Very glad that you recovered her and yes, your sequencing in correct. If in doubt, do not turn off your x-mitter until your boat is out of the water, safely cradled,and shut down.

Alesandro,
To be honest with you, I would only use a cup seal or an o-ring seal if the model's stuffing box were really deep. Maybe 6 inches or so. All other time, I simply use grease in the stuffing box and a nylon washer on the inboard end of the stuffing box, held in place with a wheel collar.
KISS principal.😊

Allesandro,
In your drawing of the shaft seal, if you were to mount an 0-ring between two of the bearins, your water leakage would be nothing.

LewZ is on the money with his description and drawing.
In almost all cases his system will work beautifully. To help keep grease in the tube, one can add a washer and set collar( or stop collar) to the prop shaft just snug enough to block grease from coming out.
A couple of other methods, hat's off to bubbleheads(submarine builders): both use o-rings. What is important is to fit an o-ring that just barely touches the shaft, ie, it o-ring ID is just a few, may .010 of an inch smaller than the OD of the shaft. The same applies to metric. one system uses compression fittings that allow the adjustment of pressure of the o-ring onto the shaft. the fitting can be soldered or epoxied to the stuffing box. Then the o-ring placed on the shaft and the compression nut added over it.
Another variation uses brass tubing. Here, using various sizes of tubing, a housing is made that retains an 0-ring between smaller diameter tubing, placed inside an other brass tube "case". The case is then placed over the stuffing box and shaft. In both cases, grease can also be used, but if done correctly, it should not be needed. Beware that it is the water in the stuffing box that lubricates the o-rings and therefore the shafts should not be run "out of water" for any length of time or at any speed.
Another method one can use is to use actual cup seals, just like the crankshaft seal on your car/truck motors. Very small diameter ones can be challenging to find, but they exist. Again, a brass tube house is made(cut and the seal placed into the housing) with the open pressure side facing the water pressure. The water again lubricates the seal. On subs that use the Engel system and pressurize their hulls during ballasting, back to back seals will keep the water out and the pressure within the hull.
I'lll work on some diagrams.

Allesandro,
I am not the person to ask your question of. I do not know. I have head that connecting LiPo's can be tricky, be it in series or parallel. I would suggest doing some web research on that. I know that my friends at the flying field often parrallel LiPo packs, but I believe that separate them for charging.
I would look to manufacturer's web sites for the answer.
Sorry.

My post was an extreme example, but having run rc subs for 20+ years, and I am a new comer to the hobby, it is easy to seal a shaft without excessive drag on the shaft.

The batteries I mentioned have the following dimensions, all mm, 149.225 long, 90.4875 high, 65.0875 wide 1089 gm for weight. As I mentioned, they have the same case as a SLA 12v 7 amp battery.

Chum, Already bought one...
Wow, where to start, independent radars, and smoke systems, (adjustable output) turrets on independent control and/or under director control. Search lights( 36" and 24"), nav lights, house light all independent, multiple sound systems including calls to stations, horns, ect. Mixed throttles, Rotating torpedo tubes, operating anchor( STBD only). operating semaphore lights. Radio telemetry including battery voltages, amp draw each motor, Lat/Long, speed, distance and bearing course., plus the usual radio signal status info, as well as GPS mapping. Just to name a few...😀

With al due respect, the comment that sealing a horizontal shaft below the waterline is "virtually" impossible, is not actual.
Modern nuc subs regularly operate at +1000 ft depths, which if my calculator is accurate, would mean a 436 psi at the shaft seal. They go down and come back up, most of the time.
Model sub builders use a range of seals that very successfully keep their pressure hulls dry. I have a seal that I have been using for 25+ years with changing, nor leakage.
Surface craft are not subject to a fraction of the pressures that model subs encounter.
A simple O ring will easily seal a horizontal shaft and, if fitted correctly, with not incur undue drag upon the prop shaft, while keeping water out of the hull.

Alessandro,
I am using batteries made by CTC Battery,Inc. They are 12.8v, 7.5A/H 96Wh batteries. The charger I am using is a ExpertPower, 12V, 1amp charger. It comes with a stereo style jack as well as an alligator clip adapter. The batteries are plastic cased and a direct fit replacement for 12 V 7 A/h SLA batteries. It has flat spade connectors for battery connections.
I have had these for around 6 years and have had good results from them. They are used to power AstroFlite 25 and 40, Super Ferrite brushed marine motors that have a 35 amp max draw. I run three motors in my ELCO pt boat and the batteries have done well. I can usually run for around 10-15 minutes as long as I stay away from full throttle.
Charging, I treat these as any other lithium battery, with lot's of respect.
Cheers😀😀

Eric,
There are a number of ways to achieve what you seek, from simple to complex. The latter involves actually using cup seals, this is regularly used by submarine drivers, the o-ring in the stuffing box is another effective method, but your model is already built so it may be impractical. Grease in the stuffing box, especially if added via a grease tube, can be very effective. One way to increase that effectiveness is to place a nylon washer over the shaft, on the inboard end of the stuffing box, and hold it snug against the stuffing box with a shaft collar. This really helps to prevent the grease from being pushed out of the SB by water pressure.
I am sure there are many more suggestions out there and hope someone else will add.

I'll throw my support behind the Dean's Design units. I have two of them and they work well.
Best part is that when I test them in the house, I don't set off the Fire Alarm! The local gents seem to appreciate that.😊

Good Morning All,
Someone please correct me if I am wrong, but most marine power systems, be they steam from coal or oil, if burning correctly, would emit a grey smoke, and not too much of it, except under severe load conditions. The real except is wood fired boilers which smoke like a banshee.
All that said, the smoke machines currently available commercially as well as those homemade unit do a pretty good job of simulating the real thing.
I would also point out that any unit that smoked "black" would, as Lew has pointed out, make a mess. If you think that dust is hard to removeform your model, you ain't seen nothin' yet.😆

Finally added stanchions and railings to the superstructures. Pretty much done except for deck stanchions and railings, which will wait for successful trials, if and when the the lakes turn back too a liquid state.

Interesting chat. The Oahu radar was aSCR-270 radar. They were quite effective, once they were believed in. One was mounted on the south facing peak of Cadillac in Acadia National Park, Bar Harbor, Maine in 1942 It was tower mounted at an elevation of around 1500 feet. The entire area was of course closed off to civilians, but the locals came to the conclusion that it was for spotting German subs and planes. Not quite. It was operated by the Army and the MIT Draper Radiation Labs. It simulated an airborne radar, as on might be carried by an aircraft. The return signal was beamed, as a TV signal to Hanscom Airfield, in Cambridge Massachusetts, ruffly 225 miles down the coast, where it( the image of the scope return, was displayed on a remote scope. Roy, you may see where this is going. Once the signal transmission issues were overcome, the next step was to put a radar in a plane, witch was done with the TBM Avenger being modified. Hence, the birth of airborne early warning radar. Everything was torn down post was. Not even a plaque to mark the achievement.
