[PSUBS-MAILIST] thruster positioning

[hank pronk via Personal_Submersibles]

I am trying to figure out the thruster position for all my thrusters before I take Gamma apart.  I have tested with two thruster pointing strait ahead.  That worked well, now I have the same two thruster on angles opposing each other.  I notice on some  commercial subs that the thrusters are vectored, in fact four forward facing thrusters, one at each corner. I assume the way it works is, all four thrusters are turned on, two in forward and two in reverse.  To go strait ahead all four turn on in the same direction.  I am trying to keep it at 6 thrusters but may need 8.
