Sir Korsky,
Considering that the Schweizer MQ8B has been supplanted by the Bell MQ8C, and that they closed the Schweizer facility, it would seem those two reasons did not pan out.

Edit: Sikorsky listed the reasons why they bought Schweizer in this 2004 announcement. Rapid prototyping was also one of the reasons. Remember they built X2 there. It would seem they started out with good intentions in the light helicopter market.
