Quite a nice boat you have! What scale is it?

Minor update- even with a much lighter tube, my initial tests showed the motor would weight down one end, causing it to sink. There is too many factors i could change right now to make that a nail in the coffin. Also, I have been looking at using gas systems either as an initial propellent, or as a torpedo's own power, which, technically, sounds much less complicated,cheaper, and easier to make, at the cost of lower range, higher operationg costs, and more potential danger.
