The quality of Easyflight's helicopter flight model is a little better than FMS, but not by much. The helis move faster, which is good, but forward flight doesn't feel right because there isn't any translational lift. Okay for learning hovering, but not forward flight.
This is often bundled with Piccofly. Add-on aircraft and scenery packs are available.
