SOH ADMINISTRATIONYep...I experienced the same...and realized that they must have updated the engine model...bottom line: They did. After I started handling the throttle very gingerly...It flew like a dream.Reported the problem and Inibuilds reports the problem is due to the more detailed engine simulation. As with a real first-generation turbojet, you have to advance the throttle slowly and steadily or the engine will stall out.
