on youtube, the groen brothers aviation company has a youtube channel known as "Groen Aviation."

JPH, e-mail, 25.06.2009 06:48

The aircraft does not rotate against the direction of rotor rotation because an autorotating rotor is in torque balance its axis of rotation, i.e all forces acting on the rotor system are resolved within the rotor system. Since torque is not supplied from a source within the fuselage, i.e. engine and shaft drive, there is no torque to react on the fuselage.

CHUCK, e-mail, 18.03.2009 16:06

I'd highly appreciate your sending of as many hi-res photos, drawings and YouTube type, downloadable videos of the Hawk 4T as possible to my e-mail address and to keep in touch with me regularly about the airplane's progress. It's somehow improbable for me to buy one at present but I'm ready to collaborate with you should any fluent technical and commercial translations into Spanish and Portuguese be required now or in the future.

It does not rotate because the small screw is a gyroscope not giving to rotate to it in a horizontal plane
