D-2 would be most easily built in the Golden plant. We can run the blades alongside of S-30V.
IMO, the best "test" run would be with the Military, ParaMilitary, Chinook or Native. We have other new model plans for the Golden plant, but capacity does have it's limitations and new models present their own challenges....sych as taking longer to get into production than planned.
Any of our Seki makers can use D-2 so really any model is possible. With the Seki makers, a larger quantity maybe necessary.
Our Taipei maker could also use D-2, but we would have to purchase the D-2 and ship it to Taiwan, which to my value system is more effort than the short run deserves.
Mostly, I would need to know that there is sufficient support to create the run...and how to make it different from a normal run to avoide confusion.
