I knew putting a new UV window sail on my U2-145 would make it
look amazing, but I was not prepared for the dramatic improvement in handling
and performance! I upgraded from the original 2008/9 sail to the current
version, and all Mylar. Lighter handling, lighter bar pressure, smooth at all VG
settings.

Put the sail on in the AM, perfect fit on my old frame all around. Mark Dowsett
my friend and WW dealer checked my work and test flew it, then joined me on a
1:40 cross country flight in late afternoon fall conditions, an amazing day! I'm
very impressed with Wills Wing manufacturing tolerances and quality assurance.
