Has anybody tried using bicyle CO2 cylinders as a compressed gas source? From the various tables I've ssn about the I reckon the small CO2 cylinder has the equivalent of about 1.5 l (i.e. the volume of a fat bike tyre) at about 100 psi, so quite a lot of CO2 for about £1 each and about £20 for the adaptor. I think the big issue is that it would probably need a regulator to drop the pressure to a more more controllable value.
As a second question I am thinking about using a peristaltic/tube pump to provide a trim function, as both models I am think about (Seehund or X-class) only have a rear p[lane so getting the trim right seems important. I was planning to have 2 small trim tanks at the extreme ends of the boat, but they could be sealed or at ambient pressure (diaghram?) by linking via a tube to allow the air to flow from tank to tank as well as the water.
