bugdevheli,
CRAN has presented a very strong reason. The following is another one.
I believe that the problem in 'Rotorland' is not the competition from other manufacturers. It is the lack of consumers. Worldwide, there is only 1 civilian helicopter per 500,000 people. The 'potential' market is certainly not saturated.
If cooperative conceptualization and technical support results in a new and better generation of rotorcraft, there should be opportunities for many. Then, the manufacturers may wish to protect their lower level details.
Personally, I believe that the
lateral twin-rotor configurations stalled at the end of WW II. Other people may have different visions.
