I had assumed it was the crankcase shape.

gcb, this is good to know. I have one of those Testors engines with carbon fiber crankcase and tank. If I am flying R/C then, the head should be down with refill tube along the top; if C/L, the head should be horizontal with refill tube vertical and open end up, correct?
I have not used these for RC but I would assume that also. Yes for the CL position.
