Hi Dels, I'm new here, just installed SF2 + E, I, and V, also your Apache along with a few other extra aircraft. Everything's working fine except the Apache wont acknowledge gravity. Unless I specifically use the collective or fly into the ground, even with the main rotor stalled and at 0 airspeed, the helo will remain airborne indefinitely. Also, when flying into the ground (rotor stalled, engine off), provided I have some forward momentum, I can take-off again. The Apache seems to generate a generous amount of lift. Can you, or anyone else reading, tell me how to fix this? Is this due to an install error, using 'easy' simulation levels, or the FM? Thanks for any help...
