Well, you CAN chop down ONE lamppost with a helicopter rotor. Can't necessarily use the helicopter again, though :).
I agree that the flight model needs some attention, the TOH model is much closer to a real helicopter, though of course still not perfect.
The one thing that stands out for me, though, is when flying with a mouse: I have to keep pushing it forwards to stay in forward flight! Would'nt this cause the stick to hit the forward stop pretty rapidly? Why does the game keep pulling my stick backwards for me? Can I make it stop?
