OOOh, you got my attention! I have an octo with the HFP but no motors out yet. Bart did have some issues with an esc and apparently brought the beast down quickly. others say it depends on what happens as there are multiple situations. If a prop breaks it mat break adjacent props as well. If you try taking a prop off and it flies that doesnt mean the same thing as a motor going out mid flight. Not sure why but thats what the masses keep saying.
