Ok Bravo73, we all understand the redundant concept. Only that out of the 150 or so critical components in a helicopter, I rather use the extra weight of another engine into those components and make them redundant, instead of the engine.
This might be really difficult for a smart guy like yourself to understand, but the engine is not a critical component in an helicopter. If you are good enough a pilot, you should walk away from every engine failure you could possibly think of. Give it some thought before enlighten us with another one of your fast-smart comments, thanks very much
Safe flying
