The tail fairing consist of 3 parts; 2 aluminium fairing under the stab, easy to make with 0,025" 2024T3 material.
The top portion is an other story. A pre-molded fiberglass that sort of fit but not ! You can see that in my first picture. I elected to cut the portion on both side that was not laying against the stab. Then I refiberglass it and I will wait until tomorrow to finish this istallation.
7/8" gap ! And if you wonder, the stab is at the correct place !
