I started with the Huey, he is really nice but I had a lot of trouble, especially for the landing. Then I took the Gazelle and that was a great revelation! This module helped me a lot for Huey and Ka50 later. Personally, I will advise the Gazelle, a very nice helicopter to fly, "easy" to a certain extent but "complicated" to master. Then you have 4 variants of the helicopter for the price of one.
