In general, there is a odd issue with the Heli and 1.0.9 updates. It says to install the Heli patch first, then the 1.0.9 one. However, when I did it, the Heli update complained that the program was not updated enough. But as the 1.0.9 patch description says, it's ok to install the 1.0.9 twice if you forget to install the Heli first. So what I did was, 1) install 1.0.9 2) install Heli and 3) install 1.0.9 again. That works.

Specifically regarding the Hangar Pack 1, someone else here said that they had to 1) uninstall and resinstall FS One 2) first install the Hangar Pack and only then 3) install the patches (Heli and 1.0.9)... that supposedly made the Hangar Pack work and behave properly. So could be that the Heli update is having no effect on the new Heli's from the Hangar Pack (if not done like described here).

I won't be able to confirm the part about the Hangar Pack myself until a few days from now because I'm still waiting on the Hangar Pack to arrive in the mail.
