Propeller Controls - Description for details.

The stress inputs must remain separated or else the clutches will break. If you find a solution to this, let me know that would be excellent.

The controls are as follows:

Lever controls main propeller spin. Forward thrust.

Steering wheel controls reverse thrust, dependent on which direction it's turned, and how far it's turned. The idea being using propellers to turn a vessel.

Other notes: I did not realize schematics don't save a signs text. the signs on the motors read (when facing the signs): REVERSE on the left, MAIN on the right.

The sign on the glass pane just says the pane is there for weight symmetry.

the sign by the propellers is just a note I left myself. not important.
