I made them myself (and engine mounts, battery mounts etc...) on my 3D printer. I printed a solid version to line up the motors then replaced those with the flexible ones afterwards.

Mine is still in the "pile of bits on the bench" stage but when I figure out how to package it I'll post some pics.
The model it's going into is HMS Cadiz, battle class destroyer which is around 1:96 scale so there's not a huge amount of space available, especially as the funnel is currently above the radio gear and batteries so I'll need to pipe the steam from the spare compartment I have nearer the bow.

I assume marlina2 is using the same as the one I linked to, no circuit required other than a 24v supply. The fan speed and the depth of water over the transducer seem to be the key factors in how much vapour is produced.
Iβm using a single funnel and twin transducers in mine, if I ever get it packaged small enough to fit in my model !

It is a piezo speaker, no spark involved or heat of any kind. it uses an ultrasonic wave to vaporise water.
For example...

I'm in the middle of building an ultrasonic generator, tests so far look good but only played with it on the bench.
Just add water... so easy enough to refill and costs nothing.

π HMS Cadiz

My dad built this over a long period of time, starting in the '80s. The hull is fibreglass and the rest is scratch built from plastic card, balsa, ply, wire and anything else he could adapt.
Although he installed the motors, props and rudders he never completed the RC installation or tested it. I inherited his boat models a few years ago and wanted to "finish the job", getting the model on the water. After installing the RC gear and batteries over the last few months, this weekend was the first sailing outside the bath at the Valley Gardens boating lake.
Happy to report that it sailed really nicely, seems to be reasonably stable although I did restrict it to calmer times when the MTBs and faster boats weren't running !
HMS Cadiz was a battle class destroyer, laid down and launched during WW2 although she didn't receive her commission until 1946 so didn't see combat with the Royal Navy, serving with the home fleet. Due to the changeover in pennant numbering she was originally allocated R09 and later, when the admiralty decided to revert to the D for Destroyer pennant numbering she was assigned D79. To reflect this my model has D79 on the starboard side and R09 on the port side.
She was sold to Pakistan in the late '50s, and renamed PNS Khaibar. She was sunk with the loss of nearly all hands in 1971 in the indo-Pakistan war.
