I got hooked on rc back in 79 as a kid . I live in Manhattan NYC and my parents took me to central park to watch the model ship's. Needless to say the coolest model I saw was a rc submarine that day. I was so impressed and taken back by this video of you building this work of art yes I said work of art lol. You have re-inspired me and not only that you brought me back to my childhood and for that alone I have to thank you. Now if you can only tell me how to break the news to my wife I'm planning on turning our study into a model ship yard for the next year without having to buy her a new diamond bracelet I would appreciate it lmao. But all joking aside awesome build thanks for sharing it.
You did a great weathering job on the sub. About 4 decades ago, I went thru a sub phase purchasing a VII and Gato class sub from an outfit called 1/32 Parallel and after market stuff for them. It's interesting to note that the entire hull of the VII fits comfortably inside the Gato. This video entices me to get back in to preparing one of them for operation before my heart stops for ever. Keep having fun.
I am blown away by this amazing work. Good job! And I really love the paint job on this U-Boat, so badass! Makes the Type VII look even better than it already is!
Very cool video. For those of us like myself who are interested in building an RC Sub this helps out quite a bit. Your build quality and paint weathering is top notch!!!
Dang ! You good at this. I can fully understand how crucial it is getting the trim just right - just like the full-sized boat. It is soo nice when things work out more less the way you planned. I think it would be impossible to get the model off the work-bench and in to the water and immediately achieve perfect trim, - but man, you were sure close.
Hi friend Congratulation, this RC/ U-Boat is one of the best i ever seen, coz it is so super weathered and aged. you have good view for details, i like your U-Boat so much. Greets from Germany
So glad I found your channel. I've always been interested in uboats and particularly the Type VII. Years ago I sent off for a printed copy of the 32nd Parallel catalog, I'm pretty sure I have it somewhere. I wanted to get the type VII model someday and was so disappointed to see the company go out of business. I think I remember finding OTW awhile back but I since then forgot about it. Hopefully they will still have this model when I have the money and room for a project like this. Looking forward to lake trials.
This is awesome!!! I still have the wooden hull of a Bismark model that I was attempting to build back in junior high. This is a super looking sub!! Nice job.
Excellent videos...all of them...all the way - I'm Subscribed! :) The comment you have in this video at 13:45 is extremely important, especially with naval submarines because when doing an Emergency Blow, if the water in the ballast tanks isn't pressurized correctly and only air is expelled, the submarine can actually 'run out of usable pressurized air' and begin to sink without being able to correct its trim. If it sinks to a safe depth, pumps can compensate positive buoyancy; if it sinks to deeply...that's it! (Or, high-velocity pressurized air can cause the ballast tank valves to freeze causing an ice blockage, as is suspected to have happened to the USS Thresher(SSN-593)...but, that could never happen with models in semi-warm water). With your model(s), if one was to accidentally use up all its air to surface and it sank, you'd have to snorkel or scuba to retrieve it...right? I was going to ask if it is (they are) 'positively buoyant' so they'll always surface; but, that can't be if the submarine(s) only submerge when the ballast tank is full. If it remained full, the submarine would remain submerged. As with 'real' submarines, they're designed to 'submerge'...and, hopefully, surface ("Das Boot" 1981 with pumps). RSVP - I'd like to know what you'd do if and when one of your 'works of art' (I meant that sincerely - they're BEAUTIFUL - aging hulls and all!) became trapped; lost; tangled in seaweed; attacked by a catfish with an attitude (or, your "20,000 Leagues Under The Sea" Nautilus is accosted by a baby squid). :D I'm laughing, but...IT'S NOT FUNNY! I'm curious because, in my youth, I was into RC cars, tanks, ships, and, Estes Rockets. I once fired an Estes Rocket into the sky and all was going well - it went just out-of-sight; we all heard the distant explosive 'pop' of the parachute release; then, we watched as it slowly came into sight and descended back to earth...then, just before touchdown, a f'ing red-tailed hawk attacked, grabbed, and, flew off with it!? I lost a $100.00 model (in 1995) because of an angry and protective raptor...you could lose "how many hundreds of dollars' because of a pissed-off fish! Viper fish have left tooth marks on the desks of nuclear submarines - imagine what a large and upset northern pike or bullhead could do to one of your submarines? At best, it may surface hundreds of yards from where you thought it was. A Largemouth bass may just destroy it! A swamp aggressive fish could drive it off course and lose it! Such a sad loss! Just curious - I've lost 'remove' toys before.
Just finding out more how difficult doing the trimming and how involved it is. There are so many things to adjust it seemed with ballast and foam, etc. Submarines RC isn’t as easy as one would think. I’m learning more. Bob Martin’s videos are very informative.
Great(Tremendous). I have to look at your 7 movies. I am admiring for the care of the detail which you show. The transformations that you brought to the submarine are also extraordinary. PS: traduit du Français en Anglais avec Reverso.
Excellent detail work and workmanship. I have built a USS Albacore from SubTech awhile back and know how much work is involved. I'm going to check out your lake trial video soon.
Your detailed work on the sub is awesome love how the sub just looks authentic from every angle great work!! Actually great work on every aspect especially the self-contained ballast/powertrain module! If I were to have the talent and patience to do something like this I _may_ have added a smoke module to the sub to mimic the diesel engines running when surfaced to recharge the battery array. Overall tho I love it, I really do!
That tip at 17:00 I find as very important due to the fact that all my testing would be in a backbay or lake and it would be hard to retrieve. So thanks again.
Awesome build, well done. Traded for a Bluefin sub not long ago, getting close to tryin her out. And yeah, go dirty up you shop a bit your making me feel bad. lol
My pool is chlorinated, yes, but I keep it at relatively low concentrations, particularly when compared to public pools. Chlorine and other chemicals and/or minerals can impact the radio wave transmission through water. Fresh water is best, with salty ocean water worst...
The lower the frequency, the better. However when you get very low, you run into communication speed issues. Realistically, in the frequencies that we have to play with legally, the difference won't be noticeable.
Video is great as is, and technical would never need changed. Given the scale of the submarine; wonder if it would be possible to *temporarily* mount/attach something such as a GoPro. Sadly that would add additional floatation and also effect trim level. Through a slight bit of editing (changing the frame rate) it would look like a motion picture
Just add weights or flotation to the "Go Pro" until it is neutral by itself. Then stick it on the boat. Should work very well and give an awesome video.
also... let me add... with the "reserve buoyancy" comes the extra effort the drive motors have to do to fight that buoyancy for submerged operation. If you can truly become neutrally buoyant you wont spend your batteries so quickly, the motors wont have to work so hard and you can dive and surface under power at trim. Also, unless the boat suffers a catastrophic failure it will stop and hover at whatever depth it loses power (if batteries died). I respect your work and I don't want to seem to be a downer.. I'm just adding my unsolicited two cents worth.
Umm... I love your vids so far... but, as a Submariner, I would suggest two ballast tanks.... one fore, one aft. this allows you to trim evenly. I know its more work, but, if you would use ballast tanks that form the side on the inner hull instead of the foam, even using box shaped tanks on the keel line, you could control ballast/trim easier. Using one servo with both vents hooked up to each side of the arm, you could open and close vents simultaneously.
your idea of twin tanks is nothing new, certainly. while it does add a degree of fine contril, it also adds complexity. Twin tanks have their purpose (I'll be using them for twin trim tanks on my upcoming 30th scale Type XXI). Having said that, the simplicity of a single tank is ideal, particularly in smaller models
Yep, I did. Thanks for the heads up. That fact was (repeatedly) pointed out to me and I now have a comment concerning the flag in the description of the video.
An easy way to remember the math in buoyancy: The buoyancy of any object is equal to the weight of the water it displaces, so volume of displaced water times density. If your boat is lighter than that it will float if heavier it will sink, if equal its neutral. Fg is the force due to gravity (weight) of the boat its Fg = m*g (g is the accelaration due to gravity 10 m/s^2) and the lifting force you can get from the water is Fw = d*V*g (density of water times volume of the displaced water times gravitational accelaration) the difference between Fw and Fg tell you how much weight you need to remove or add for the desired buoyancy. You can approximate the shape of the sub as a cylinder that should be good enough. Or you could use two cones.
A lot of rich people start a business specifically to take out huge loans with it and "pay" themselves millions. The business eventually goes bankrupt and the founder retires on the money they funneled through it to themselves. In other words crime makes millionaires and billionaires in the West, not that capitalism BS - that's for honest people and broke bitches that tried to make an honest buck 👩🔧🇺🇲🛠️🇷🇺
I'm insanely impressed by your work with all the painting details, coatng, salt, and wash. Looking forward to see it in the lake. Could you please share some links to places who sell the type VII, the engine and buoyancy tube. Thanks for sharing.
Hey there Bob, saw some clips you put on RUclips and immediately got enthousiastic, though this clip in particulary, is a few years old. It's amazing what kind of artist you are. Keep on going! Greetings from Holland. By the way, what intro-music did you use for this and you,re ohter clips?
Very cool indeed. Where is the antenna for the sub. is it up where the servo arms are at in tht container? What is the range of the sub when you hve it on the lake? I'm curious have you ever used a camera in one of your subs just to see what is under the water of a lake or is that not possible? Thanks for the video I really enjoyed it and had always thought I'd like to try my hand at a sub never thought too much about it. I tend to stick with RC planes & Helicopers
Antenna for low frequency radios typically lie along the watertight cylinder. Range is a function of depth. The further out you go, the more shallow you need to stay. Water content also plays a huge part. Let's just say you can get plenty deep to get into trouble. Video has been done extensively, but for the most part, all you see is haze and floaty bits of algae.
Spray paint the inside of the water tank with hydrophobic spray for 100% water extraction. Leave just a strip at the bottom, where the water collects for the pump.
Buckle your seatbelt, because this hobby is not cheap. Parts alone for a boat with these specs will set you back north of $3k. Want it fully built and ready to go? A good rule of thumb is to double your parts price... $6k(ish) turnkey.
Of course you can. Is it the easiest and simplest solution? No, not really. Anything is possible given time, talent and resources, but whether that solution is best is really up to the modeler to decide for themselves. Twin external tanks are more complicated to implement properly than a single, central tank.
That is correct. This is what is termed a wet hull submarine. This allows for a lighter sub and a modular control unit that can be swapped between boats.
Low frequency radio signals propagate quite well through water, however any contamination of the water in regard to minerals or chemicals drastically reduce range. In freshwater, you can expect up to 30ft of signal depth, dropping exponentially as your horizontal distance increases. Radio signals "bounce" off the surface of the water. In chlorinated pools, you can get 10ft or less before the chlorine affects the signals too much. In salt water... a few inches at best.
Please email me details and I will be very interested in exploring this further. Bitte mailen Sie mir Details und ich werde sehr daran interessiert sein, diese weiter zu erforschen.
If you check the SHOP section of my website at www.nautilusdrydocks.com, I offer quite a few large scale kits for purchase, including kits of this Type VII.
If you let me know what parts you're missing, I can try to see if OTW can supply them individually for you. There are also lots of aftermarket suppliers for these kinds of parts. Shapeways.com allows you to have really detailed parts printed in almost any scale for the uboats.

You got the flag upside down, for the rest the sub is rock solid
Yep, I did. Thanks for the heads up. That fact was (repeatedly) pointed out to me and I now have a comment concerning the flag in the description of the video.
+RCSubGuy yeah I know, I never read the entire threat of a post, just the "Best off"...hihihi
the maiden run also looked real good...
Just to be picky, it is not a flag, it is an Ensign and it is 'worn' not flown but a huge Bravo Zulu for using the correct Kriegsmarine battle ensign.

I beg to differ. You are likely thinking of the Revell offering in 72nd scale. This is an OTW boat measuring about 82 inches in length.

Awesome explanation, great video
I was on a real sub recently when they tried to get the trim. It took weeks to get right
Very nice model dude
I know it's an old video. I've got the 1/48 scale and I can't imagine the 1/32nd scale, that thing must be a monster in size.
very nice work.

Could you please share some links to places who sell the type VII, the engine and buoyancy tube.
Thanks for sharing.
NasrafRekcos Check out www.otwdesigns.com for the cylinder and hull kit that you see in this video!
You could add some partitions inside the ballast impede displacement of too much water.
that's so cool. if I had a pool that's what I'd use it for haha.
Enceladus TheMistGiant me to, since I can't swim😂
nice I wanna see that nautilus submarine when its done that will be really cool
Thank you for the math :) Love your RC subs
Hey there Bob, saw some clips you put on RUclips and immediately got enthousiastic, though this clip in particulary, is a few years old. It's amazing what kind of artist you are. Keep on going! Greetings from Holland. By the way, what intro-music did you use for this and you,re ohter clips?
My intro music was made just for me by Tom Martin of OBT Music.
Very cool indeed. Where is the antenna for the sub. is it up where the servo arms are at in tht container? What is the range of the sub when you hve it on the lake?

Thanks for uploading!
Now that is impressive!
Spray paint the inside of the water tank with hydrophobic spray for 100% water extraction. Leave just a strip at the bottom, where the water collects for the pump.
fascinating really like watching
these are really cool. definitely want one now. how much would one of these be complete ready to go with everything needed? subscribed.
Buckle your seatbelt, because this hobby is not cheap. Parts alone for a boat with these specs will set you back north of $3k. Want it fully built and ready to go? A good rule of thumb is to double your parts price... $6k(ish) turnkey.
Well done!
Fantastic model, but the German Ensign is upside down.
Hi
That model is amazing!! Wunderfull job.
Do you make that model allso to sell? And if you do what is tha prize?
Sehr gut .
Submergir nivelado , muito bom .
Valeu Bob .
If you put baffles in the tank with transfer holes it would allow the water to evenly fill without sloshing.
There are baffles in the ballast tank.
Could you use high temp epoxy to seal off chambers for the battery and actually use the exposed ballast on the submarine for authenticity?
Of course you can. Is it the easiest and simplest solution? No, not really. Anything is possible given time, talent and resources, but whether that solution is best is really up to the modeler to decide for themselves. Twin external tanks are more complicated to implement properly than a single, central tank.
The inside of the sub is not watertight? The interior is flooded except for all the electronics in the plastic tube.
That is correct. This is what is termed a wet hull submarine. This allows for a lighter sub and a modular control unit that can be swapped between boats.
Great video. Wish I could build like that. The only point is that the Kriegsmarine flag is upside down. Apart from that, the detail is amazing. Keith
verry niceeeeee U99 wolfpack
good drydock!
Muazzam güzel... Harika 👍❤👌
Are you making bits for the sub using the 3D printer you got going on in the back ground?
For the large models, does it become practical to have fore/aft trim tanks and gyro type inputs to keep the boat level?
Verry intresting!
Nice boat

just wonder that R/C signal with submarine in the water is a little bit weak signal or same signal
Low frequency radio signals propagate quite well through water, however any contamination of the water in regard to minerals or chemicals drastically reduce range. In freshwater, you can expect up to 30ft of signal depth, dropping exponentially as your horizontal distance increases. Radio signals "bounce" off the surface of the water.
