This is the engine complete with the exhaust and deflection system. Note the rods that control the angle of the exhaust The angle can be changed as desired to control the direction of flight from straight up (exhaust directed down), to hover (down with thrust equal to the weight of the plane), to forward (directed rearward -- remember Newton's Third Law--), and to a limited extent reverse. Go to the photo of the underside of the plane and you will see how all this fits together. Underside It is beyond a doubt the noisiest thing we have ever heard. And we used to tune and drive racing cars. If you ever get a chance to see one of these things at an air show, don't pass it up. Return to Main Page
