hi there, im a mechanical engineering student and for our computer aided design module (CAD) we have been given the task of modeling a gas powered helicopter. im interested in modeling this helicopter, the kaman k-225 because it was the first to be gas powered and because of its simplicity it would be easier to illustrate all the moving parts, engine and drive train and how they all move together. do you know where i could get good blueprints of this helicopter? thanks
