The MORE engines the more chance of having one fail, IF it wont fly on ONE, what use is it? Take a look at what the Plane IS with one engine stopped But NOT feathered It's VERY Assymetric. (Hard to control) and the best you could achieve is an extended Glide for all your good work. On top of that you have the annoying out of SYNCH Inevitable without CS Props in normal flight. Constant fiddling with the throttles. Nev
