The previous post on this topic got me wondering. Just how different
would the two engines need to be?

If propeller direction is all that you need to change, could you just
add a reverser gear?


How about one engine in the middle, with chain driven gears turning the
props on the wings.

Oh, wait. I think that's already been done.
