Hi Cliff, still working on the PLC code. I was going to add a sensor to
determine the thruster location. Not sure how to tie the rotation of the
actuator motor to the plc.
But I have time to work that out if that can be done.  I haven't specced
the sensor yet, as i needed to make sure the linkage and all the UHMW parts
were working properly and the clearances for the fiberglass shells are
working before I start to cast the fiberglass. I have a lot of room to
mount them on the deck pan once i figure what to use.
David.
