Hi Alan, My use a very similair design with one motor on each side and I
don,t have a rudder. With one full foward and one full backward, I can almost
turn on the spot. Same as a bulldozer. So no, I would not waste time on rudders. De : owner-personal_submersibles@psubs.org
[mailto:owner-personal_submersibles@psubs.org] De la part de Alan James Hi
all, I
have been looking at some videos of a small 1 person semi-dry ambient sub in
action. This
sub doesn't have a rudder & just uses differing motor speeds to turn. As
I'm building a small 1 person sub of a similar size with two PWM controlled
motors I'm wondering wether
a rudder is going to be a waste of time for me. I did have a rudder in my
original design. Any
thoughts on this thanks. Alan |
