Odd Ball Engine...

Maybe they naturally run faster in RH operation.

Back when model engines were new, the most popular engines turned CCW. Prop manufacturers thus mostly made CCW props.

Unless you produced such a good engine that people would carve their own props (some did), you made it run CCW.

One spark engine (GHQ) got a very bad rep for not running. It was setup to run CW. Note that I read this, GHQ was even before my time. :-)

As flying CCW in the circle became the standard (more or less), some folks who flew racing events used reverse pitch props to counteract torque and prevent the plane turning in on them.

For CL stunt flying, it doesn't matter because if it helps you upright, it will work against you when inverted. other methods are used to trim the plane to fly the same upright and inverted.

Many do not turn the rudder these days because it can induce yaw that hinders as much as helps.
