Anime - Japanese Animation
Baka - Japanese word for idiot or fool
Loosely put an Anime Baka is someone who's crazy about Anime. However interpretation's may vary. I tend to think of Anime Baka as meaning something like drooling fan boy/girl.
Wrote this a long time ago. Too short for an article:
Perverted - Hentai in Japanese. But the word pervert means deviation from normal or accepted. So, how can all guys be perverts?
Did you ever notice that the sex scene in the movie is generally at about the same realative place as the guitar solo in a song?
Conways is the bible for ships. There are two books the orange is later ships, the green is earlier ships. Conways is the considered the only athoritative reference for ships within Big Gun R/C.
Indiana Cannon - These are the common turret style cannons seen on most battleships. They can have 2 (or even one) 3 or four guns on each turret. The design is inefficient as propellant gas is leaked into the magazine, but they work reliably so the inefficacy is just worked with. Accumulator volume 1.5-2 cubic inches per barrel.

MPA-7 has a 7/8" bore. Paired with a buna-ball valve with a 1/2" seat gives about a 3:1 mechanical advantage. Since the pressure on the ball is perpendicular to it's surface the force on the ball gets canceled out accept for the force acting on a disk the size of the valve seat which is .5 inches in this example. Assuming a system pressure of 120 PSI:
3.14 * (0.5/2)^2 * 120 = 23.6 lbs of force holding the ball in place.
The MPA7 has a straight 7/8 inch bore so at 120 PSI so:
3.14 * (0.875/2)^2 * 120 = 72.2 lbs of force the actuator has available to open the valve.
The mechanical advantage is 72.2 : 23.6 = approximately 3:1 Arizona gun - MJV-2 Valve 1.5-2 cubic inch accumulator.
Other Gun types - Cannister guns, negative pressure guns. MPA series. Hybryid cannon from Greg.
Canister guns are designed as a round canister with turret and accumulator round on top of each other. This is the design I was independently working on. They are reportedly taller/deeper than stock Arizona guns. Look into these and see if you can find any drawings/pages.

Dual Torps plans accumulator 3/4" ID PVC pipe, length 3.5" Fired effectively at 80-90 psi. 1.55 cubic inches for two barrels .75 cubic inch per barrel.
To use electric instead of air use an EV-3 Mouse Valve instead of the MAV-3 poppet valve. Slightly heavy Mouse vlaves: EC-3-6. Lighter manifold mounted valves: ES-3S-6
Balsa - If you go to your local hobby store, you can usually find a few sheets that fit the bill. Hobby stores buy assorted balsa - some sheets are stiff, some heavy, some light, some soft, some hard. Just stand there and try bending them as far as you would need to for your hull, one at a time. Another test I do is to lightly poke the surface with a fingernail. If it dents, and it bends, it's good to go. -Rob
Look for balsa with little or no grain. It should easily flex almost like rubber.
Wood filler - This I've found to be the best for smoothing out gouges and dents in the hull. Sands like balsa. No strength at all for hole repairs, good only for dents and gouges.
It is water soluble if immersed for a long time (gets soft) so apply a coat of primer or dope before you paint it with something like hobby paint.
Can be smoothed with a wet paper towel when wet, no sanding required.
Tools - Dremel, table top drill press and common household tools. Wood hull - bandsaw scroll saw and sander. Ben prefers table top 1/8" blade bandsaw.
