LOL, I just gotta ask... how in the world could the helo flight model be any easier than it already is!?
As for the Longbow games, they have some really good weapon systems and avionics modelling, but like all other 'combat' flight simulations the flight model is as far from reality as can be. The emphasis on the flight model is performance characteristics, while the handling and dynamics are on the one hand, very highly simplified and on the other, just plain wrong.
Sure the dials might show the right numbers under the right conditions for the given weight/torque/speed/height/load/etc, but the helicopter nevertheless flies nothing like a real helicopter, and Jane's is one of the worst in fact, as they don't even get the basic cyclic vs pitch relationship right.
I don't really expect much more from the OFP helicopter than is already there, after all it's not specifically a flight simulator, just needs to clean up what it's got and get rid of that pedal to lateral cyclic coupling. There are plenty of more fundamental game issues that need attention before significantly improving the flight model.
Just my 2c worth...
