We are already used to ERS amazing freeware releases and the S-76 is no exception. The team has been hard at work for quite some time and, although they are planning on some improvements, they have released this model earlier today.
In fact, during the installation they let you know that:
While this helicopter is functional as it is, we are improving the overall functionality to make this helicopter more enjoyable. Over a period of time, we are planning to improve the engine and systems logic to match the real world S76 helicopter.
So you should expect some upgrades soon.
