I've tested the scenario, and it plays really well as far as I can tell.
Maybe a bit on the easy side? I've achieved a decisive victory first time around, which is something that just doesn't happen to me
All in all, this scenario is really enjoyable, not too complicated to grasp and not too long to play. Well polished and clean look, so go publish it right away!
One or two things that could possibly be corrected, but that's just my opinion: give more value to the airport victory hexes, and keep the troops inside the helos, for the player to deploy (just keep the deployment points marked using text as you did). That should raise the challenge a bit if needed, but it's up to you.
