I guess I didnt really answer your real question - can you tell a "wing
dropper" by looking at the aircraft and the answer is no.
You could check the washout with a digital level but there are so many
variables (eg: the flaps) that I doubt you could reach a meaningful
conclusion. If the aircraft is fitted with stall strips it might suggest
that there was a tendency to drop a wing (before the strips were fitted).
BTW many commercial aircraft have stall strips fitted - the problem isnt
just limited to homebuilds.
The only reliable way is to test fly the aircraft with an experienced Europa
pilot.
A word of caution regarding stalling with the wings level. We discovered on
our aircraft that the instrument panel wasnt put in straight - ie: aligned/
level with the wings. If the aircraft is stalled with reference to the
instruments (ie: turn & slip) it drops a wing because the aircraft isnt 100%
level !!!. Till we realised what the problem was, we always wondered why
the ball wasnt in the centre.
The fact is many Europa panels arent level - I suspect its a common problem
with homebuilds.
