You say,
"The certification of ANY Russian product in the Western world is problematic, ......... Third world countries accept the Russian standards .."
I believe that Canada has certified one Kamov model; but perhaps some consider Canada as a third world country. Make sure you get payment from the Canadian government before delivering the S-92's.
Enough humor.
Your avid support of the tail rotor configuration seems to be softening a little, at least in respect to the coaxial configuration. Is this a harbinger of a future relationship between Kamov and Sikorsky?
If so, then perhaps United Technologies / Sikorsky can put aside the old conflict with its former employee, Charles Kaman. Then the intermeshing configuration can continue to make the significant advancements in Rotorcraft that it formerly did under the Germans.
