When I originally started fitting the empennage fairing I made the rookie mistake of trimming it to the scribe lines and it was about 3/16" too short on the leading edge. Everybody says that these fit horribly anyway, so when I ordered the intersection fairings from fairings etc I ordered their aftermarket empennage fairing as well.

Unfortunately, the fit on it isn't great either. It has significant gaps around both the vertical and the tailcone that I think can only be alleviated by splitting it down the middle and bringing the two halves closer together.

Since I'm going to have to do some fiberglass work anyway, I went back to the OEM fairing which is quite a bit smaller with tighter radiuses which I think look better, although this is just a personal preference.

I sanded a fillet to the leading edge and laid up an extension of fiberglass and flox. Once this dries, I'll pop it off the fuselage, sand it smooth and trim it to get back the 3/16 or so that I erroneously cut off. It's actually fitting pretty well everywhere else,

To finish this, I think I'll add a bit more of a wrap around where it meets the leading edge of the h/s and I may need a little filler to tighten up the gap around the fwd section of the vertical, but otherwise I think this is going to fit pretty well
