"About the snap turns:
They're possible in an odd and probably unexpected way, you have to lean with the helicopter at 90 degrees to the left for example and then quickly turn on auto-hover. It turns you around about 90 degrees and AFAIK it's only possible with the Comanche."
hmm, I really can't reproduce that, when I tilt and turn on auto-hover and tries to turn the chopper fast comes to a hold.
In anyway it is not the way the Comanche is supposed to do snap turns and sideways flying: it should be done simply with the pedals controls up to the speeds mentioned above.
"Are stealth arguments even valid, are radars fully simulated to warrant manual landing gear? Id like manual landing gear to be an option, but for simple reason of having more control over the aircraft, rather than (probably)in game none-existent stealth issues. Any info on how these will work?"
I guess the stealth arguments aren't valid, but it just looks so stupid when the you sneak around at low altitude and speed and the landing pops out :) and maybe they will make it valid :O radar simulation is very crude, in the old game 'Comanche 4' it was simulated very fine, where both landing gear and the stub wings would increase radar cross section and firing the gun would increases IR signature thus compromising stealth.
