This is the original object source code for the r_aileron 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 r_aileron are called. This assures that the animation applied to r_aileron is also applied to those parts which use r_aileron as a parent part.
