Not. At least, only in the sense of RTB. This is where we came in. It might
not produce any thrust, but it should solve shouldn't it?

Yes. I wish!
Next trial:
Config file:
<control-input axis="/controls/engines/engine[0]/throttle"
control="THROTTLE"/>
<control-input
axis="/controls/engines/engine[0]/boost-control" control="THROTTLE"/>
Output:
YASim solution results:
Iterations: 1
Drag Coefficient: 1000
Lift Ratio: 1
Cruise AoA: 0
Tail Incidence: -0
Approach Elevator: 0
CG: -3.412, 0.000, -0.201
Do you suppose that whatever is or isn't in
"/controls/engines/engine[0]/boost-control"
Is breaking YASim?
And I've tried initializing "/controls/engines/engine[0]/boost-control" in
hardcode, and in Nasal, and in .XML - no difference. I can only think that
initialization creates the property with a null value, and then only gives
it the correct value after YASim has tried to use it and failed. I can show
that this is the case with NASAL, otherwise I wouldn't need this:
if (mp == nil){mp = 0};
Any better theory?
