sounds like G forces are not a major factor in causing damage. G forces from hard pulls or hard hits, so long as nothing hits the turbine. A long time ago I had a jet central turbine, and on a hard landing it shut off. It has flown a lot since then but I recently wonder it it may of rubbed from that, not sure why it shut down. It said LOW RPM and it was at idle on landing, and it hit pretty good but not hard enough to break anything.
