Re: [PSUBS-MAILIST] OSS Thruster Question

Rotating thrusters means you need both hands to control the them. When you
peer through to front viewport you have to stick your arms backwards. With
fixed thrusters you can steer with a (mobile) joystick. You might save on
the electrical through-hulls but you need two more complicated mechanical
hull penetrations. Using one vertical thruster is ofcourse still a very good
option.
