I did not do any formal flight testing with my new factory supplied
wing root fillets, but noted that I had better control while
thermalling, and could circle tighter. I can now use landing flap when
needed in a small strong thermal, whereas before I would have great
roll control difficulty trying to use that flap setting.
I did find that these fairings are now available, at Al's website:
