Thanks for the suggestions guys. I have four sets
of tips for the ship (plain factory tips, short factory
winglets, 16.6 extensions and Masak winglets). I rarely
ever use anything but the Masak winglets although the
problem is the same regardless of which tips I select.
The problem has always existed (was this way when
I bought the ship but it was several flights before
I went fast enough to notice) and has never gotten
worse. I will double check all of the tape and mylar
seals although the seals were replaced four years ago
and the right roll at high speed is the same after
the new seals as it was before. The problem does seem
to exist only at the negative flap settings...I never
fly over 80 kts without going to -1 so I have not tried
to fly 86kts at 0 setting...something to try and see
what happens. I will continue to work on it.
