I was thinking of using baking soda method for missles. If and when I get that far on my Ohio.

As long as you launch when surfaced I think you will get satisfactory results. A soda vinegar reaction can't compete with CO2 cartridges or rocket motors in terms of pressure,but then again, it's relatively safer.

Looks fun

Funny stuff from the Great Race too.

could automatic pitch control electronics be miniaturized further and used in model torpedoes too? Not only for pitch but azimuth too? I don't see why not. Make miniaturized device and combine pitch but azimuth into one tiny unit? Tiny control rods to the tail surfaces or a tiny gyroscope forward to elevate the need to tail surfaces? Just thinking out loud.

Maybe use one of those RC heli heading lock gyros to make it run straight.

Here's a 1/12 rc torpedo from Japan
540mm length, 40mm diameter

Corona receiver
550 lipo battery
2 FA 130 motors
PICO X2 Servos
MS10 ESC
PS10 automatic pitch controller

Funny and timely. Drachinfel just posted a video article on 19th century early torpedo inventors.

'Experimental Torpedoes of the 19th Century - The Roads Not Taken' Just posted yesterday. Yes attempts with Vinegar and baking soda too. lol

I have a question; I think electric torpedoes have been well demonstrated. But could automatic pitch control electronics be miniaturized further and used in model torpedoes too? Not only for pitch but azimuth too? I don't see why not. Make miniaturized device and combine pitch but azimuth into one tiny unit? Tiny control rods to the tail surfaces or a tiny gyroscope forward to elevate the need to tail surfaces? Just thinking out loud.

I looked for an "al in one" flight controller for a micro quadcopter to fit the bill. It has stability control and ESC built in. The only problem is the form factor (cross shaped).

Maybe make one in 1/35

I probably should have posted this version first. This first attempt was without the launch lock and check valve. I also had to fix all the torpedo leaks. An O-Ring replaced tape, JB Weld replaced CA glue and threads replaced a press fit.

I'd love to see how this prooves out. The trail of soda and bubbles should be pretty cool, too!

Had the same idea 20 years ago. Tried it with a pen full of baking soda. Squirted some vinegar using a syringe. My reaction produced little gas. Either the amount of reactants were insufficient or expired.

How about using hydrogen peroxide.

My first attempt was to slip fit the brass tube nozzle to an O Ring and let the pressure launch the torpedo. This arrangement did not allow enough pressure to build up. Locking the torpedo in the tube and allowing the pressure to sufficiently build solved that problem.
