Are the wrinkles proportional to wing flexing;- effect of mass, manoeuvre, thence control effectiveness.
Could be some interesting test flying in these areas !
Didn't there used to be something in the books about surfaces being "clean" in the context of all weather ops and contamination?
I know use of speedtape as/is fairly widespread for small dinks (as per K'n'Cs comment) but wonder if there is any guidance on it being used to cover significant areas of aerodynamically important surfaces?
