I wanted to make sure I understand the correct way to refer to thrust angle direction. If, for example, I am sitting in the airplane (pretending to sit) and there is some right thrust angle, does that mean the crankshaft is pointing a bit to my right?

I wanted to be sure since, using the above convention, the crankshaft of the mounted engine is actually pointing slightly to the left. Does anyone know a reason why this would be beneficial, or do I have an atypical ARF? I read a lot of the threads about thrust angle and I think I understand it, I'm just surprised to find left thrust on the 4*60 ARF.

Thanks.
