John, did you know that on the P-38 they made both engines critical after test flights showed buffetting with the normal twin rotation?
Yes I was aware of that but it was not done because of any consideration given to reducing VMC on one engine but to eliminate the aerodynamic problems of the buffeting casued by the unusual configuration of the twin booms with a stbilizer tieing them together When inward rotating CR engines were used. The single XP-38 was inward rotating but all subsiquient marks were changed to outward rotating
I am not aware of any other CR aircraft that are not inward rotating.
Maxpower that is true they are rare but one example is the very last production version of the Twin Commanche, the PA-39CR
But when it comes to RC its really a dead end not worth the added problems.
