I've read and re-read all of your comments with much interest and there's one
observation
I'd like to make. I'm fairly sure that the early Classic Europas had
no engine offset and that the designers might have thought it unnecessary with
only 80hp from a 912UL.
My reasons for thinking this are that the topic never got mentioned by anyone at
any time. The brilliant Don Dykins makes no mention of it to my knowledge in
his paper "Understandings the aerodynamics of your Europa".
Furthermore when I was building my aircraft over 20 years ago, the cowls needed
at least as much trimming and fettling as do the XS cowls to get them to match
the fuselage, which makes it seem unlikely that the cowls on the Classic were
serving as datum for correct engine/propeller alignment.
My final reason is of the "proof of the pudding" variety, in that my Classic has
a very pronounced swing to the left when applying power at low speed. Not that
I noticed it, but someone else who was unfamiliar with my Europa definitely
did notice.
