Ours at school would overheat idling on the ground if you were not careful. That was also turning a prop pushing a tremendous amount of air over it. Those are also prone to hydro locking from oil draining into the lower cylinders, I don't see anyway to turn it over by hand.

What would really be bad butt is a rotary radial, pretty flipping dangerous for that application.
