Back when I built the wings, I was on the fence about whether or not to install the stall warning kit in the left wing. It wasn't really needed since I was installing an AOA sensor but since the kit came with the wing I decided to go ahead and install it. It was a decision I soon regretted because I hated how the vane looked sticking out of the leading edge.
When connecting the wing wire harnesses to the fuselage after I installed the wings, I inadvertently switched the stall warning wiring and the power wire for the pitot heat and managed to fry the stall waring circuit board and consequently the stall warning has never worked since the airplane's been flying and I've been planning to remove the vane mechanism and fill the opening when I got a chance.
Today I removed the vane mechanism, fabricated an aluminum doubler, match drilled it to two holes in the leading edge on either side of the vane opening and riveted the doubler to the inside surface of the leading edge. After that I mixed up some epoxy/flox and filled the slot. Once it cures, I'll sand it to match the shape of the leading edge. Once the airplane is painted it won't even be noticeable
