Compare Arma 3's helos with Advanced Flight Model active and Auto Trim on or off depending on if you have a joystick or pro helo cyclic, and compare it to Flight Simulator X, X-Plane, EECH, or DCS. Try flying around. Also try over-torquing by yanking back on your assigned collective control. The sluggish rate command controls I could probably live with, but this midget available torque needs evaluation on the BI devs' end.
