Yeah, that's a bug.  Power is power.  If the prop wants to sync X
horsepower at Y RPM, then the engine ought to be defined as producing
the same X hp at Y/gear-ratio RPM.

Let me take a look.

Indeed.  The problem is that simply exiting the loop in
stabilizeThrust() isn't enough to tell you what the problem is.
