Hell, they way you guys are talking, we all should add a complete second engine and all its control systems.
Where does this crap stop? Go fly on a four engine airliner.

While I wish the EC-2 had separate power feeds, rather than sharing one, I can also understand Tracy's reasons for not being too worried about it.  You have to draw the line somewhere.
