Yamato is about the biggest and most heavily armed and therefore the most expensive.

I think that the hull was around $250. The first five cannons were $1050. I already had the CO2 bottle for Marauder. The pneumatic fittings have been about $250 so far. I would guess $2000 will get it battling on the water.

You could build a cargo boat for $200, I guess.

In Alex's Yamato, I have attached the front three turrets to one frame and rotate them with a single servo. The back two turrets are mounted the same way. The two servos will run from the same channel so that one stick will bring 15 barrels to bear. One stick will fire all 15 simultaneously.

Later I would like to fit the 12 barrels on each side and have them firing at the same time through clever plumbing and electronics. Some boaties try to control each thing individually. They will twiddle and press and push up to 9 knobs buttons and stick to try to attack. Some people wish to get channel splitters so that they can have more buttons!

The cargo vessels play an important part in the points scoring. A game can last three hours (we haven't played a game on my dam yet). There is a points system involved. Cargo vessels can make runs and earn 1000 points each. They also earn bonuses if they go in convoys of five or more. Cargos loose very few points for their team if they are sunk.

A battle ship looses a lot of points when sunk and gains few points for shotting other ships.

There is a lot of strategic planning involved to win a tournament. You need to choose a time when the other team is reloading their boats and try to make a convoy run with an escort battle ship.

You could say that the cargo ships are the most important part of the Big Guns. Battleships, however, shoot.

You can read the rules at http://www.ausbg.org/rules.html

ah i see, so the cargo vessels have to do laps around the battle area carrying the ammunition? now that is cool on so many levels.

will they let you make a cargo ship out of a cheap-o static model made into a running boat? most interested Smile

The cargo vessels are supposed to be 1:144 scale replicas of period ships. I don't know if anyone would care too much so long as they can shoot you and sink you.

The hulls must have windows cut at their water lines and then be covered with thin balsa wood to allow for ball bearing penetration. I don't know how this would effect your plan.

You could always make a boat from scratch to save money. You would just need scale plans, or a model that is close to scale to copy. You already have a radio and, no doubt, small DC motor and batteries. You could use micro switches for forward and reverse.

You should email the guys if you are interested. Seeing them in action and talking to the owners is a good way to get a feel for Big Guns.

Has anyone tried using "Greek Fire" (google it) in Big Guns yet ? Wink

That would have to be one of the most awesomely devastating "secret" weapons ever invented in the history of naval warfare..

I'm sure it wil be against the rules, but I like it because it is one of the few instances in history where a "secret weapon" actually worked more than once.

greek fire.... that liquid stuff that just keeps on burning napalm style? that would be sweet,

phil would be the say in this one but i reckon it would be getting close to being allowed, i mean googling around theres high pressure air torpedos, black powder depth chargers, mines and things.

one thing i dont see is any salvage vessels, someones gotta make one for sh*ts and giggles Very Happy just cruise out and crane up the wreckage from the bottom.

The models must be scaled versions of boats from 1900 - 1946.

Flame throwers would end the day very early.

Coastal guns are allowed. You don't have to worry about getting sunk. You just need to build a coastal target and arm it.

afaikr greek fire burns on contact with water (as well as if you light it)

spockie, i think if you made a "scale" greek galleon with its traditional scale speed of 3 knots and with scale armor, so say tissue paper perhaps?

Sidewinder's just freakin awsome! Very Happy
So by land guns do you mean like land based rc guns? Has anyone made a sub and entered it? I'd imagine some vertical rockits shot right up into an overhead boat would be devestating!!! Shocked
hehe glen we should both buy cheap kid toy trauler boats and fit them with weapons and go at it! Smile

The land based guns don't have tobe radio controlled. You could work them manually.

There are subs. Their main problem is knowing where the subs are and aiming up on your target.

Sidewinder is very cool. Daniel has his work cut out for him to drive it on various surfaces during combat.
