The Cessna Aerobat Spin video raised a question. I take it that stopping the engine during a spin is not SOP. Would you mind explaining what happened?
It's actually in the POH. Words to the effect that 'during prolonged spins with half tanks or less, engine stoppage may occur. But this does not adversely affect spin recovery.'
What happens is the fuel slugs outboard, uncovering the pickups in the tanks. I think Catherine said it takes about 13 turns before the engine will stop.
