I was wondering how the Harrier works in regard to the vectoring of the thrust to hold the stright and level hover. I had this idea for a unit to do this job with a single valve.I don't know if this is how they do it on a full size or not,but this valve has been stuck in my head for a year.Maybe it would work for models only. Maybe it would not work at all.A floating disk valve,controling four ducts,with gyros.Could some one look at this and blow it out of the water,so I can get it out of my head,and think about my prop-jets again.

Thanks BOB
