at www.rcwarbirds.com a guy made depth charges for his sunderland that actually worked! i know he lives in australia where rules are different then in the states(i assume) is it legal and how are they made?

I guess he just has little water tight capsules with NitroGlycerine or a thermite explosive so when the capsule hits the water the a hole in the side of the capsule leaks water in which causes a chemical reaction with the chemical and goes BOOM. Another possible way is to make them like mines and just call them depth charges anyway, you know, like a sinking mine. Take a capsule and fill it with Sulphuric Acid, Gas, Potassium Chlorate and sugar. The Acid must be concentrated, careful it is corrosive and toxic. The capsule when dropped should float just under the surface of the water. When it comes into impact with something it will go BOOM!!! That guy must be part of the Australian Battle Group.

i dont know if i have the guts to attepmt that[X(] how would i load the capsules if they explode when hit[sm=eek.gif] by the way my name is jimmy to[8D]

lots of ways to skin a cat... I would try to find some raw sodium (be sure to keep it in oil) once it hits the water...boom( this is why you keep it in oil... the moisture in the air will react with it) something the size of a 1/4 inch bb or a small marble would do it-probably be more than 'scale' size boom... Very stable until then, just don't get it wet.

single best way for a depth charge is to place potassium in an old style metal film cannister. Place holes in the cannister. As it fills with water the potassium produces an exothermic reaction with water forming heat and hydrogne. It will explode.
Weighted cannister and number of holes determines depth of explosion.

No matter how I look at it, these things don't sound really safe..... I've read about one method where you place black powder in a cardboard cylinder and attach a fuse, place the cylinder in a tube and ignite the fuse so it detonates the charge just as the cylinder falls under the water surface. I guess this is all a question of timing. As i see it, anything that involves explosives is a not a safe thing... remember, safety first and safety always!

People People, Jimmy here just asked about how to make depth charges. And here we have people scaring the hell out of him, lol. Don't be a wuss, explosives are part of the fun. But like the pen guy said, safety first. I hope no one reading this is a cop, . Jk. Pleased to meet you too Jimmy. Get it? Hi Jimmy, You're jimmy, everybody loves a jimmy.

Cheers,
Jimmy

Yeah, but I still wouldn't want to run my sub through a sea of depth charges! Seen enough submarine movies to know what that looks like!!

i wonder who came up with the idea with just using C02 cannons, lots of club rules state you cannot use any other type of weapon besides those cannons. Who came up with this rule and how did it come to be? Wouldn't it be more funner if there were other weapons like torpedoes, depth charges, catepults, and radio scramblers?

So where do you purchase potassium?

A Chemical dealer, like the ones that deliver to Schools/Universitys. You would probably need a Licence, or just a decent reason for having it, I doubt they would accept "For blowing up Joe Blogs Sub".

PS: I don't mean to start bringing up old threads, but these things need answers 'ya know?

What is wrong with a safer version of mines or bombs ?

I would always be a bomber.

Sure as hell do not want anyone bombing me.[:'(]

Acoustical bombs or mines should be doable with some brainstorming by us.

EVERYBODY walks home complete.

there is a way to make torpedos work.
in a torpedo have about 4 parts condys crystals and 1 part glycerol seperated by a thin glass divider. for this to work, impact with the boat should break the torpedo and when these to mix, it makes a pretty nice explosion. would probably work better out of water though, maybe some mini dive bombers would work.

thinking again maybe not as a scale dive bomber would be very small. lol maybe with an exception of scale.

I herd of someone that did a limpit mine so he had a littl sub and drove it smoothly to the other sub and 1min later BANG this was acheved with some potasiem

cool

Honestly guys, [link=http://www.rcuniverse.com/forum/m_3338378/tm.htm]there are rules to the game read up on it from some of the club sites posted in the pinned thread[/link] at the top of the combat forum.

There is up to $1200 US dollars in some of the more complex ships out there battling. No one wants their investment destroyed. The idea is to be competitive.

There are times for theater and special effects such as a explosive depth charge, but for the game, literally blowing up someones model doesn't work.

Aww but that would be alot more fun.

yer I can see where you are coming from but yes If they don't want a BLAST then they should get one there self

I recon It's because you dont think you could make one

You'd better start living in the real world when you start talking about using any kind of explosive device in the water. Several reasons why not to even think about trying it; the DNR or whatever outfit controls your fisheries will not like it a bit, just like using dynamite for fishing. The Police can come down and get into your case if you have fireworks laws where you live. Third, blow up my $1,000.00 boat and I'd guarantee that you'd have a face full of me to deal with!

well make shuer you don't get hit then

AJOE is all for the testing to be done on his best ship. Just to show he understands the damage done to his boat first, will be enjoyed by all first.

make sure you get a video

i don't know if anyone is still looking at this thread but one thing i know that works is bottle rockets. if you launch them parallel to the water maybe a few inches above the water, they will drop in and travel just under the surface and then explode, just like a torpedo. it is really neat and i've done it a few times(can't recall where i was though, cause they are illegal here) they look exactly like torps when they are going under water, its awesome to see.

That sounds cool, but people wouldn't want pyrotechnics blowing up their ships. For anti-submarine warfare, though, depth charges are the only realistically effective weapon, so maybe an exception should be made in the case of attacking a sub.

I had an idea for mare realistic non-pyrotechnic torpedoes though. What if you were to take one of those Airsoft gas-filled shotgun shells, and mount it in a gas-powered torpedo so that the firing pin would be pressed on impact... a blast of about 5-10 BBs would make a big hole and probably sink the ship in one or two hits. These torpedoes would be as wide as a 12 gauge shotgun shell though, a little thick for the scale they would probably be used at.

ASW is not much of an issue in model warship combat. It is very difficult to build a submarine in 1/144 scale (the most common scale), and arming one is even more difficult. Making it reliable is even tougher, and less than half of subs that are sunk are due to enemy action. There are not very many at all, so most of the time you don't need to worry about them. Also, a submarine is not a particularly effective combatant because it is very slow. It needs either a disabled or very unlucky victim to score a hit. For simplicity, torpedos are fired by a contact button in the bow, though they would not be effective beyond about 6" anyway. Because the operator needs to be able to see his vessel, the advantage of stealth doesn't exist, especially because everyone is paying close attention to the uncommon combatant. Submarines also have very little reserve bouyancy, so if one springs a leak for any reason, even a leaky propellor shaft, it will sink rapidly. Also, my club (the WWCC) allows all ships to ram submarines.

Current ASW tactics in the WWCC mostly consist of ships trying to run over the sub to keep it under and unable to attack. It is also possible to sink a sub with gunfire, though the sub operator must have really screwed up to present a good target. The rules allow for a single cannon to be mounted through the hull to fire downward on subs, but amount of work for such a small threat means that nobody has done so. The rules also allow for a weighted line to be dropped on the submarine, making it unable to surface. Again, nobody has tried this yet. Most clubs have outlawed pyrotechnic devices of any kind due to the danger of mounting it on a very expensive, very flamable ship (and even worse: in the proximity of other very expensive, very flamable ships). I tend to doubt our insurance would cover us (nor could the club survive) if there were to be an incident.
