There is a manual in the resources/ documentation folder in the folder for the Hunter in the Community folder but I attach it here as it can be a bit difficult to find it for some casual users of MSFS with it's very strange installation locations depending on where you bought it !
I note that it has zero setup instructions and while I can fly iy I have not been able to attach the power control levels ( throttles) to an axis . The manual notes that you can't control the engines independently due to a MSFS limitation.
I also found the collective animation is very laggy compared to actual collective movement and I think the Trq changes are very laggy .
