Sooo, is it possible to change the direction which the rotor spins? I have a dodosim heli where the rotor rotates counter clockwise (like most american helos) I wanted to change the rotor spin clockwise (european style), is it possible to do this by modyfing the .cfg or .air file? I have been tweeking with them but didnt find anything usefull.just to mention I modified a few of the parameters on the .cfg file like p_factor_on_yaw and gyro_precession_on_yaw parameters. with no much change on the simulation thanks for the help . fred

Sorry, I don't think this is possible.There are only two ways I know to do this, change the animation key frames or change the animation script.Both require access to the original model so it can be recompiled.As far as I know, there is nothing in the .cfg or .air that can reverse the animation.So dodosim must do this for you....but that means a branch in their files they may have reason to be reluctant.Danny
