Hi Ron (rparigoris),
Thank you your response. You have given me some scope to investigate my
slightly drooping flaps (when retracted).
I did wonder if there was scope for adjusting the length of the main flap
pushrod from the control end. I’m also not sure how to access the mechanism, as
I am not the original builder.
Furthermore, I am curious in the comment that a builder might droop the
ailerons for more efficiency, as I would have thought the reverse would be
true, ie, drooping the ailerons would increase lift, and therefore drag. In the
80s, the Lockheed L-1011 did the opposite, raising the active FBW ailerons in
cruise by a few degrees in order to reduce drag and increase range.
Drooping ailerons would certainly make stalls lively!
