Yeah, i definitely feel for Belsimtek. Reading Wag's last update on the ED site, it seems that the delays are stemming from features that aren't related to UH-1 compatibility.

IMHO, ED should have limited the 1.2.4 patch to whatever was necessary to implement the Huey and whatever features were complete and stable by the time Belsimtek was ready to go, and then left the rest for another patch - even if that patch were to be only a few days or weeks behind.
