We should avoid creating an alternate history, where the Sikorsky X2 concept on FLRAA or FARA would have succeeded if only the original demonstrator team had been in charge. The same scaling up issues would have plagued any team in charge.
Remember that the X2 completed only 22 flight hours over 23 test flights. Compare this to the Bell XV-15 which accumulated 530 flight hours on one airframe (700 flight hours total on two aircraft).
