The model, by .org forum user jpb63 is the fruit of the conversion from an older FSX model and the author added some objects that can be attached to the helicopter in a folder.
Don't expect a highly complex helicopter with realistic systems. This is a simple project of a simple helicopter, developed mainly for the joy of the average simmer and it should be seen as just that. There's no pretension of being anything different, which is perfectly fine. Sometimes, we need easy, simple things, just to enjoy flying around. We sometimes tend to focus too much on "realism".
It's a great little addition to our hangars.
