Hi Terry,
Interesting input, supporting my first thought expressed in my message
yesterday. That is what David Bossomworth called the "cookie test" , I
think it was, when he took me up as passenger: " Now I will let go of
the stick, and the plane will tell who ate the most cookies" . Right
wing drop!
Best regards,
Svein

Hi Svein,
I think it may be a little soon to say you actually have a 'heavy
wing', since (as I understand it) you haven't flown with two people of
equal weight. Even with two people of almost the same weight, our plane
would bank in the direction of the person weighing just 10 pounds more
than the other, right or left.
regards,
Terry Seaver

Bob,
Interesting thought, but the wash-out is not the cause in my case.
I am not familiar with the term "accellerated factory built wings".
The kit I bought from the factory 5 years ago came with the wing ribs in
place (but not reinforced to the beam and bottom panel), bottom panel,
leading edge and top panel (actually, the seam between bottom and top
panel is at the l.e.). Apart from bid reinforcements, aileron weight
boxes, meachanics, etc, the only major thing was to glue on the top
panel. For this weights (sand bags) were used, and if one did not
support the underside of the wing in the process, one could conceivably
introduce a twist, i.e. change the washout.
On my wings I checked the washout and it was fine. I did not check it
in absolute terms because I did not have a proper template for the tip
section, but I checked that the tip on both wings had the same
difference in angle between root and tip when placing the flap
installation template on the two positions. Also, I checked the aileron
and flap washout (factory built, termed "accellerated kit") and they had
exactly the same and correct washout as per the manual. Finally, I
rechecked the washout on my wings this afternoon, and even with a very
accurate bubble level I could not see any difference.
So maybe the incidence angle of the whole left wing on my plane is the
cause of this wing being "heavy" in my case? No, the left wing is
actually a small fraction more up at the root than the right one
(whether this is the cause of the left wing drop in stall I cannot say
for sure, but theoretically it should stall just a little before the
right one).
Best regards
