- This is my scratch built U505 Submarine that I have been trying to make operational for some time. Its not designed to submerge when static but I came very close. This has been an ongoing experiment for some years and I believe I have overcome many problems.
Very nice video
Super like 👍 2
Congratulations, for the good content of your Channel👋💯👍💯💥
Excellent work 👍 💥💯
Hi, thank you so much for your very kind comments they are most appreciated.
Cheers, Paul.👍👍🙏
Hi Paul, great video. I really enjoyed watching the sub working 👍👍
Hi Windy, glad you enjoyed the video and thanks for suggesting the Remote switches and in the wiring they work very well. Cheers, Paul.👍👍🙏
Hi Paul, very clever man with a lot of knowledge 👏👏👏 cheers Al
Hi Al, Thank you for the very kind comments, not sure about the "lot of knowledge" though.
I have had many problems to solve to get the Sub operating quite well.
All the best, Paul.👍👍🙏
Bravo Paul...well done. It looks great. Quite speedy too. Lovely.
Hi Tim, I started this scratch build 10 years ago and finally got it working quite well. It was only running on one motor when it went under and hit the pool wall. If I had used both motors it would have been a lot faster and probably got damaged. Cheers, Paul.👍👍🙏
Super U Boat-Video, Paul. Thumps up and keep it up.
Cheers Andre. 🙋🏻♂️🙋🏻♂️😀😀👍👍👍
Hi Andre, I am very happy you liked my U-Boat video. Cheers, Paul.👍👍🙏
Hey, Paul. I know you felt it was a partial success, but from where it was and the work you've done... this is an awesome go. It is a wonderful model and to see it running in your pool is fantastic. I love the cap, too! This is great to see!
Hi Anthony, This has been a long experiment in getting the ballast pumps,valves, electronics etc to finally work well. After all the failures I am happy with the end results. I will add some more weight to the bow section, this should make it dive earlier when running. It weighs approx 25 kg so takes some stopping. I only ran it on one motor as its too powerfull on both motors.
The Cap came from my visit to see the U17 in Speyer back in May this year.
Thanks for your support in my various projects its most appreciated. Cheers, Paul.👍👍🙏
That's great model Paul an enjoyable video...cheers James 🙂👍
Hi James, I started building the Sub over 10 years ago and after many issues finally got it working. Glad you liked the video.
All the best, Paul.👍👍🙏
@paulvozman842 Yes, it was something different to watch Paul 🙂👍
Hi Paul,
Yes you have done it very impressive indeed so well done. Will you ever take her out to a boating pond so she can show her paces that would be great to see also. Also thanks very much for the mension and forefilling my wish.
Cheers Robert.
Hi Robert, I am happy you finally saw my Submarine finally working reasonably well. It needs a lot of room to overcome the positive boyancy but at least it went under albeit with a thump against the pool. A trip to a lake would be good but it must be shallow.😂
All the best, Paul.👍👍🙏
Beautiful, even it still has a little weight issue to be fixed. Even fantastic, as it is scratch built and made functional by your own efforts! Thanks for the video, Paul, have a fine week! / Chris ⚓
Hi Chris, getting the trim right is not easy a few grams can often make the balance good or bad. I started this scratch build 10 years ago and have finally got it working quite well. Thanks for your support and kind comments. Have a great week.
Cheers, Paul.👍👍🙏
A good video, Paul. I like your U boat
Hi, I started this scratch built U505 almost 10 years ago. It has had a number of issues to overcome but finally its working quite well. Glad you liked the video and my Sub.
Cheers, Paul.👍👍🙏
Brilliant effort Paul. Now it is time to commence mass marketing. They will sell like hot cakes. You might want to partner with a Chinese manufacturer though. Good on you for sticking with it, it's very satisfying to see a positive outcome. Steven.
Hi Steven, There are a number of manufacterers who make cylindrical removable diving systems take a look at "The RC Sub Guy" on CZcams he is the real expert in Sub modelling.
My plan was to try and make my Sub operate like the older prototypical Subs actually dived and surfaced using ballast tanks,pumps,valves etc. I started building mine from scratch 10 years ago and have had many problems to overcome. I think I have finally solved all the issues ,just some extra gramms of weight on the bow and its done. I was very happy to see it dive allthough it hit the end of the pool a bit hard. It weighs approx 25kg so takes some stopping, it was only running on one motor at the time, its good I didnt run both motors.
Thanks for your support in this project.
Cheers, Paul. 👍👍🙏
Hi Paul, that's quite an impressive piece of kit! Wow 🤩 Honestly, I can't even understand how it submerge and then get on the surface again!
Hi Erik, it works the same as the older prototypical Subs.
The ballast tanks are open at the bottom with valves at the top closed. When the valves are opened the water enters the tanks and the Sub submerges. To surface the valves are closed and air is pumped into the tanks at the top pushing the water out. Its been a labour of love getting everything working but finally it seems to be ok.
Cheers, Paul.👍👍🙏
@@paulvozman842 Thanks for the explanation. I never understood however where the air comes from if the submarine is submerged. It's a great wonder of technology, and your model is really fantastic!
@@railway187 Hi Erik, The air supply in my U Boat comes through the periscope when its on the surface. Because its normally driven under water the positive boyancy is enough to bring it back up after submerging. The problem is when its submerged if the pumps are turned on water can get inside the sealed compartment. On the real Subs air is stored in air tanks for surfacing and trimming. I wish I had that system.
I am going to show my Chinese Loco on Wednesday for your Frankenstein challenge.
Cheers, Paul.
@@paulvozman842 Cool! I am looking forward to seeing your Chinese Loco running again.

You may be getting air trapped under the deck. Is it a dynamic diver? With decks awash like that it would dive dynamically quite well.
Hi, I have vents under some of the deck grating that allows are to escape. I incorporated them some time ago as some air was bring trapped. Its designed with positive boyancy so should be driven under water as in the video. Its a delicate balancing act to try and do static dives again as shown in the video. This has been a long experiment but finally getting close to working while under way. Thanks for watching and the advice. Cheers, Paul.👍👍🙏
@@paulvozman842 I have an Eden (Later Sheerline) Akula submarine. I always only ever filled the ballast tank so that the top of the conning tower just broke surface. I used the forward planes to dive and maintain depth, with an automatic leveller on the rear planes. It could sail around at a constant depth hands free. If I lost sight of it (old eyes) I could switch off the transmitter and a lost signal detector would blow the ballast tank. With a little positive buoyancy, it managed to negate any tiny leaks. Your project looks ace for a scratch build. Well done!
@@akula9713 I follow the "RC Subguy" Nautilus Drydocks on CZcams who has some amazing Subs and dive systems using the cylinder types. These are very controllable but as mine has front and rear ballast tanks and a seperate water tight compartment for the electronics I dont have the ability for such fine depth keeping.
Its taken me 10 years from starting the build from photos to getting it almost working. It weighs 25klg empty is 1.35m long, 12cm wide and 20cm high.
Take a look at my video called "Tommys final Sub Update" where i show how my sub works.
@@paulvozman842 The Eden boat just had a large central tank. It used a windscreen washer pump to pump water in, via a pinch valve. The pumped in water would compress the air inside the tank. The pinch valve was just a servo cam pushing a spring loaded rod through a block of plastic onto a ball bearing that sat on the inlet water tube. The operation would go like this.
Dive servo neutral position..pinch valve closed
Dive servo to the right…..pinch valve opened, microswitch activates pump, ballast tank fills, compressing air inside.
Dive servo neutral position ..pinch valve closed, microswitch deactivated. Water can’t get out of the tank.
Dive servo to the left pinch valve opened, compressed air in tank pushes out water, boat surfaces.
It’s been my most reliable boat so far. A very simple system.
