How without the spark from the plugs if the magneto is off... diesel is different as its compression , hence the pull to stop on a tractor... what obvious thing am I missing?
Huge inertia of the prop is what I was guessing. Much more than the flywheel on a car engine.
Rotaxes do stop violently - it feels quit horrid, rocking the whole plane. Less inertia in a wooden/plastic prop, and (possibly?) higher compression.
