I have a 1987 Ventus C that I purchased in 1995. Love
the plane but it wants to roll to the right at high
speeds (90kts or greater). Actually I guess it always
wants to roll to the right but I start to notice how
much left aileron pressure I have to apply to counter
the roll at the higher speeds, especially above 100kts,
for any period of time (long final glide). It makes
my arm tired. At speeds below 80kts I don't notice
it. I have tried various riggings with the flaps/ailerons
but other than slight improvements I don't seem to
be making any progress and have just 'lived with it'
over the years. I'm afraid that the problem might
be 'built-in' to the airframe with one wing having
a different angle of incidence than the other. I sent
an email to Schempp-Hirth about this and never got
a reply. Anyone have any ideas?
