R/C torpedo system testing

[@DerredmaxTRIAX]

That's really good, You should patent that ! Nice job....

[@RCSubGuy]

Nozzle alignment is a big part of this, but also bear in mind that there is a liquid sloshing about inside the body, affecting its center of buoyancy. The biggest thing that I found is that canting the rear fins results in straight operation UNDER the water, however the torpedos quickly become buoyant as the liquid gas is expelled. With that being the case, only the lower fins are in the water, resulting in either left or right steering depending on the direction that the fins were canted.

[@RCSubGuy]

My pieces came from 32nd Parallel, a company that went out of business back in the '90's. Everything will need to be made from scratch. You'll need access to aluminum tubing and material to turn the caps and tails from. A lathe would be perfect, but you could also get by with a drill press or other stable drill platform. Nothing on the market in that scale. Bear in mind that these are basically rockets, so few manufacturers will accept liability for selling them.

[@RCSubGuy]

Its not just up and down that needs to be corrected, but left or right. Adding spin to the torp is necessary to counteract any slight variations in nozzle direction. The creation and implementation of an elevator system like you mentioned is certainly possible, but the amount of work necessary is very high, as is the possibility of losing the weapon at the lake or pond. The torps I made are cheap, easy to fabricate and work well. I just need to tweak the amount of gas and the fin angles...

[@matthewallen3375]

That system looks really good. Thanks for the explanation over top, very helpful.

[@alanhaskell65]

Nice Bob.. You always come up with great ideas.. Now all you need is a guidance system. Alan

[@deutschlandairsoft5980]

you should see if it has enough power to puncture a boats hull made out of the thin sheets of balsa wood and sink it. That would be cool especially if you replicated the sinking of the Lusitania

[@vettevet2002]

+The Pyro122HD it would be even easier to replicate Lusitania if one were to make sure it contained a secretive arms cache in the forward hold just like the real ship did...

[@paulpaulsen7777]

Deutschland Airsoft Well the Lusitania wasn’t sank by a torpedo- they sank themselves and claimed it to be a torpedo to have a reason to attack Germany. Was an inside job

awsome!! saw a rc battle ship drop depth charges and actually blew up vid! man this is greatlol

[@RCSubGuy]

The gas is not CO2, it is airbrush propellant. CO2 operates at far too high a pressure for safe operation in a model sub without many pressure reducers and adapters. This system uses a simple servo to push the torpedo off its seal, allowing the gas to escape from the rear nozzle. There is no spring assist in this prototype version.

[@3Dprint4you]

Why would anyone give this a thumbs down. Brilliant! Great video thanks for sharing.

[@woodbarter5713]

+Don Sanchez Probably because of the horrendous distraction of the noise pollution track he laid on it. I wanted to listen to his commentary but just couldn't hang. I didn't give him a thumbs down but others may have for that reason.

[@barriewright2857]

Thank you very much, just brilliant lots and lots of very useful, information and what to do if you want to build your own rc sub, thanks again, and brilliant.

[@MannyCAM]

Awesome video clip Bob thanks for posting

[@RCSubGuy]

Torpedoes aren't an off-the-shelf product. There are huge liability and safety concerns that mean most vendors steer clear of it. You can try the Sub-Driver website. They have a small torpedo system you can buy. Other than that, however, its a matter of buying raw materials and turning out your own weapons of mass destruction (aluminum tubing, resin endcaps, brass tubing for nozzles, etc). Good luck!

[@thomash2831]

Great stuff but what about dropping the volume on the back ground music it is way too intrusive!

[@Mada1100]

RCSubGuy Can you please make a video explaining more about the actual torpedo and the barrel used to launch it. I am very interested in the system that you used. Also, what is the torpedo body made out of that allows it to float? I would appreciate any information, thank you.

[@poseidonam]

I didnt read all the comments, and im sure you thought of this... How about retractable wings like a arrow tip or spear gun. Retract them so it would fit in the launcher, and then pop out and guide the torpedo straight once it was out. It might loose some distance, but might track better.

[@mikel9567]

Cool idea. Real torpedo's have spring loaded fins that extend out once it leaves the tube. I bet if you could figure out something like that you could have bigger fins for more stability. Have you tried a little weight in the front?

[@1SemperDad]

Never hear of spring loaded fins. Not on American torpedoes at least. Personally fired MK14, MK37 and MK48.

[@RCSubGuy]

My best results were obtained with fins applied in a straight orientation and launching the weapon from the surface.

[@abyisaac8583]

How much does the whole boat cost including the torpedos.

[@RCSubGuy]

There are not many places that will sell torpedo kits. Its a small hobby and in this world of sue-happy people, the danger of a torpedo injuring someone is too great a risk for many talented builders to offer a kit for sale. That having been said, check out the Sub-Driver website for most of what you'll need.

[@idabour]

this is very cool, keep up the good work

[@RCSubGuy]

That would work great (I think), however the launcher is only a hair larger in ID than the OD of the torpedo. No room for a spiral, unfortunately.

[@woodbarter5713]

The video would have been really good but the "music" is MADDENING!!! I will never understand why YTers feel the need to follow the crowd and ruin their otherwise great videos.

[@adrianlarkins7259]

+Wood Barter Agreed. The music drove me nuts.

[@brianpayne2478]

If the music was actually good, and the volume turned down, it would be alright. But it's not. So it's not.

[@paulpaulsen7777]

Totally agreed! Fucking annoying music

[@crocogile2352]

WAY COOL I COULD SEE THAT SYSTEM ON A MODEL PT BOAT I THINK IT WOULD WORK GREAT AND LOOK REALISTIC FIRING OF A TORPEDO OF A THE PT BOAT ( KEEP IT UP )

[@NoName-ue5mp]

This Toredos is very week but it can finished the battle in one second. You make the gun shot in the battle ship please

[@itolond]

few question on this: so the propulsion is compressed CO2? what scale is the torpedo are you using a one way valve to fill sealed with a 'o' ring until torpedo is release (assuming electromechanical release), is there an spring assist at all?

[@RCSubGuy]

I'll be posting up a follow up video in the next week or so once I get the entire system installed. I'll then go into detail about how its built so others can give it a go as well.

[@STARDRIVE]

It mimics a steam torpedo, but how do you plan triggering it? You actually do stuff, I'm more of a theoretic: What are your thoughts about dual screw electric propulsion with one of the props fixed to the hull? Fast & straight, and you can incorporate a reed-relay (thus triggering it by a coil surrounding the torpedo tube.) A neodymium magnet on the tip makes it stick to a dedicated target boat; also providing detection to start a sinking/roll-over sequence including special effects. Plus a magnet makes stray torpedoes easier to retrieve by using an ironclad vessel. You can even make the battery switch over to a blinker LED after a timed run... I'm sure your practical & uncluttered design is one of the reasons you made it happen in real life ;)

[@RCSubGuy]

Bear in mind that there is very little room in there. Add batteries, a motor, reed switches, ballast, etc and you'll be challenged to maintain buoyancy. Is it doable? For sure. Worth it? Only you can decide!

[@STARDRIVE]

Buoyancy, good one. Elementary, yet didn't cross my mind to be honest.

[@TheWinning247]

Ronald van Kemenade Coin cell batteries and a Pager Motor? Discuss.

[@STARDRIVE]

TheWinning247 Saves a lot of room & weight.. I wonder if rechargeable coin cells exist... If rechargeable, one could seal the torpedo perfectly, having just 2 contacts for charging flush with the hull. Any ideas for sealing the drive shaft?

[@RCSubGuy]

Ronald van Kemenade I did experiment with pager motors and they work well. They are not very powerful, but can spin a 1/4" or 3/8" propeller alright. Sealing the shaft is problematic as traditional seals do have a high friction. I simply ran mine wet and doused them with oil after each run. They're cheap enough that you can simply replace them if they do eventually die. This way the only thing that needs sealing is the battery compartment, which is very easy to do.

[@ithaca2076]

This is beautiful:)

[@Kevin_Lu]

if im going to buy a torpedo, do i need to buy the torpedo launch system and the gas propellant? Where can i get these items...

[@ninashiva67]

funktioniert prima, allerdings reichweite nur 10meter?

[@77chonyc]

That last one is very dangerous. That can easily swing around and blow up your own submarine. Please be careful when explosives are finally fitted in torpedo. Its all fun and games, till someone gets hurt or even dies.

Might have a military application. Don't laugh with the rapid development of drones this could be something the military might use.the miniaturization of weapons this concept could have a future.

[@1SemperDad]

Hope the warhead on that torpedo has ACR (Anti-Circular-Run) :)

[@randomguy9898]

How did you produce the torpedoes themselves? Are they like the original 1/72 versions, made of cast resin?

[@RCSubGuy]

randomguy9898 These particular weapons were created using aluminum tubing and resin end caps. The big issue is adhesion between the two unlike materials as the tubing expands and contracts drastically during fueling and firing. A flexible adhesive such as RTV is needed.

[@randomguy9898]

RCSubGuy Thanks! Can I also email you some sub questions to the one you listed on your site?

Would like to know more about how you did the torpedo... (the mechanics)..... Is this something you sell?

[@RCSubGuy]

If you check out another video on my channel under the OTW Type VII buildup in 1/32 scale, you'll see the actual construction process as well as testing. Since this video (and the one that I referenced, I've decided to play with the idea of electric propulsion vs. gas. Gas torps are just to unpredicable in their path, prone to leaking, and somewhat dangerous, frankly.

I like your torpedo and the work you've done on it. However, my Mark I prototype RC torpedo will be superior in other parameters. BTW, I'm thinking your torpedo goes too fast (and runs too shallow) in relation to your sub's speed and possible surface target...out of fairness! ;-)

[@RCSubGuy]

In fairness, this was my first Venture into torpedo creation. My new electric Torpedoes are far superior. I anxiously await a detailed video outlining your weapons. Be sure to let us all know what you have come up with.

[@boboala1]

;-) I would tell you...but then I'd have to sink you! Keep up the good work.
