Apparently the N-1 never actually fired all 30 engines simultaneously before launch, so there was no way to detect plumbing issues. Additionally, their control scheme was designed to shut down the engine opposite to any failed engine, meaning that they had very little engine-out margin in the inevitability of an engine failure. All in all, we can (and have, with the Falcon Heavy) do much better.

> meaning that they had very little engine-out margin N-1 could complete the mission with up to 4 engines turned off from the start. And I guess it it's not from the start, you could turn off even more engines and still have a successful flight. Even though Saturn-V is heavier, N-1 has more lift-off thrust. Partially to have this kind of redundancy.
