BTW, I dont understand why both the left and right engine rotate clockwise (if one of the engine rotate anticlockwise, the effect would be equal theoretically, is it because of fuel consumption?)
On the counter rotating prop aircraft, It dramatically enhanced the aircraft handling during engine out. However, since the aircraft needs 2 different set of engines and prop, usually cost more for Maintenance . (Compared to conventional, same part can serve either side of the engine)
