Yes. I was messing around in the training arena with it. Every time I took the me163 into sustained neg Gs under red out conditions the engine/igniter would turn off as if I had manually shut off the engine. I could then turn the engine back on normally. I repeated this several times. I was trying to get the me163 to blow up under heavy neg Gs, but the engine kept shutting off instead. I'm just curious if this is a bug or part of the plane design?
