You're a cheap troll and trying to derail the thread. Totally incapable of holding a civilised discussion. Rest of us were discussing it technically..That is what we usually say. The result is that the US leads the world in aviation.
What was so 'technical' about your post no. 4? Zilch.
Getting back to the topic. Knowing both USMC and Army personell having flown on this thing in the horn.. they find it thoroughly unstable in vertical flight.
So what triggered you in the post 4? Check post 11 by Fenrir, he or she basically proved me wrong by showing some info about similar project conducted by other countries, WITHOUT GETTING PERSONAL. And I acknowledged it in my response. No one was sad or happy. A simple objective discussion.
When you alter the paths and axes of propulsion, tilt wings or tilt rotors, you will alter the characteristics of flight in the appropriate axes. That is just the laws of physics. To begin forward flight in a helo, we have all seen where the helo had to pitch down, an opposite flight characteristic of fixed wings aircraft. The early days of the helo, today dubbed the 'God Machine', was not very favorable.
Excellent post . ...yes this is a good point
