corrected with re-fairing when the glider was refinished in Poland


Whose winglet kit did you fit to your Mosquito, how did you know the
correct toe in/out angles (i.e "Straight & True) & how did you measure
the the toe angle when fitted.

I'm dubious about the factory fitted winglets on my Discus B - again the
cut angle on the winglet doesn't match the Schempp tech note. But the
performance doesn't seem to be any worse with them than without and they
stop the tip dolly falling off (When manoeuvring on the ground, before we
get ay sarky comments!) so I continue using them.
