Well, the flight models are good, i dont have allot experience on heli's though but the Nemeth feels better (more mechanical) than the lago's
The panels are much better and also the avionics.
You realy need to learn the startup procedures because else you do almost 15 minutes on just the starting when you need to find all the switches.
You can also fly the beasts entirely from the virtual cockpit, what is realy nice when you have trackIR, every switch works in the vc.
you can also walk to the cargo bay and all stuff....
And the smaller stuff like the hoodlem, the colibri and the mi-2
The fly like they are little! So you realy feel like you are flying with them.
not like the standard bel....the newest addon is the kamov! That one, i think it is cute!
