Hi there. Fast planes like Carter's converted Me-163 Komet, FS France converted Me-262, Alphasim's He-162 Salamander, crash in mid air when I fly them in QC. Not in level flight, but always after some manoever. The red sign that appears says OVERSPEED. If I have the "aircraft respawn" box selected, the plane just stays fixed in mid air, completely blocked when I touch the controls. The Me-163 is the worst of them all crashing almost instantaneously after the slightest move of the stick. What explains this? Can anyone help me fixing this?
