Secure that garage door pull rope! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-d_sWx9WLwGM.html I've seen too many helicopter videos where some stupid piece of rope, tarp, etc, flies into the main or tail rotor, and major damage ensues. Otherwise, very cool. I still have the full plans for the Rotorway 162 that I wanted to build way back in the late '80s.
