aileron seals on SZD-45
Thread drift warning light on.
FWIW one day standing next to my Grob Twin Astir TF in Parowan some guy [ I forget who} Stops by and says: "Hey if you put zig zag tape on the elevator on the fixed piece in front of the hinge line it will help you out"
So I did and he was correct.
Warning light off
