. What I have noticed in this release is that the turning rate of the blackhawk helicopter seems rather fast at ~ 2π/3 rads/s. The helicopter can weigh anything between 5 and 10 tons so I do believe that this is unrealistic. On that note, it seems that most if not all of the helicopters can turn just as fast on the ground as they can in the air. This is also unrealistic since the friction between the ground and the skids or wheels is far greater that between the skids or wheels and the air itself. As the the rotors spin up, this rate of turning should increase as well since the faster the main rotor is turning, the more lift can be provided and the less friction there is between the ground and the wheels or skids.
My next issue is with the WZ11 which is the PLA's scout helicopter. To maintain level, forward flight one must keep on tracking the mouse forward to compensate for the tendency of the nose to keep on rising. This becomes rather annoying after a while as you either get worn out trying to keep it level or end up flying far higher than you usually would.
The slow decent times for the helicopters still remains. A helicopter changes its roll and pitch by altering the pitch of the main rotor blades passing through a point. For instance to make a helicopter pitch forward, the rear of the helicopter needs more lift comparative to the front. In order to achieve this the angle of attack of the blades which pass through the rear side of the helicopter are increased. Altitude is also controlled by the angle of attack of the main rotor blades on the whole. In theory, the rate of decent could be as fast or faster then a (helicopter shaped) stone falling out of the sky if the angle of attack is zero or below eg 10 degrees below the horizontal.
I also appreciate, due to the nature of the BF2 engine, that many of these things cannot be fixed and that also one or more of these flaws may have already been brought to light in other threads.
