[PSUBS-MAILIST] vertical thruster orientation

[hank pronk via Personal_Submersibles]

 Jon,I am mounting my vertical thrusters on E3000 the same as Gamma.  I agree with Alec completely, and if you have an entanglement you won't rely on thrusters, you will simply air up your MBT's.  I don't know how your compensating your motors, but there is an added benefit to having the prop at the top with oil filling because the seal is at the top.  Gamma has no pressure compensation on the vertical thrusters, they are simply filled with oil.  I replace the oil (WD-40) at the end of the season and thats it.  Hank

 Thanks for the feedback folks.  The issues of bearing wear and running in reverse mode to control a positively buoyant sub is well taken.  I was thinking more about potential entanglement and having maximum forward thrust available to help push to the surface if necessary.  I will have to think about this some more.  

Although I was intent on fixing the thrusters permanently for simplicity it looks like I do have the option to retain the original rotating configuration and maybe that would give me the option to position them for multipurpose use.  If I take this route I plan on utilizing the SNOOPY approach of locking them down rather than having to hold onto them.
