This is the original object source code for the rudder generated by FSDS Pro v2.33 from fxpaint.fsc. Note the Call32( ... ) commands just before the Return command at the end of this code. This is where the "Child Parts" of the rudder are called. This assures that the animation applied to the rudder is also applied to those parts which use the rudder as a parent part.
