And to clarify, like above, I'm not anti-single either. It's just that it seems those who endorse this product tend to dismiss the risk as if it's inconsequential. It's not. You don't even need to have an engine failure to be a glider; a prop hub or governor failure, etc will result in the same. Having said that, I think it's a great product, but you wouldn't catch me flying it over mountains, especially at night like I see all the time in the western US.
