>>1258021 Some do... those are called "handed" props (bc they are like your hands that way). However, that does add to the cost, and now one engine is more "critical" than the other in case of failure on one side. Overcoming that left-turning tendency depends on the plane design. Size/configuration of the rudder, engine distance and angle from the centerline. Push-pull types (engines in front and rear of the fuselage) cancel each other out. Pic is Burt Rutan's Boomerang... assymetrical and weird-looking af, but it was designed to minimize all of that for easy handling even with an engine failure.
