I appreciate your input on this, but the aircraft in question is not supersonic.. The shimmying begins soon after take off with the airspeed set at 250 on A/P.. That's my usual routine with IFR cross country traffic.. Until now, I have not had a problem with this, but I'm believing that your former statement about "poorly designed" may be the case... The paint is pretty, but the insides are rotten, me thinks!! But, they are FREE and that is certainly something to be glad of here. Not all designers, well intentioned and benevolent as they may be, can get it right, first time, every time, huh? I really appreciate all the designers efforts... They make this sim interesting!! Roy
Never mind the mule, just load the wagon.
