Having wised up about the proper way to place the empennage fairings on the tailcone, I remade one of the marker tapes and refit the fairings and they were darned close. I sanded a few areas. It's pretty difficult to get the things to stay in place even with a couple of clamps but I did the best I could and I was satisifed with the fit after a little sanding. Then I placed the attachment clips to the bottom fairing, aligned them, bent some of them and drilled them to the bottom fairing, then fit the top back on, checked the fit, clamped a couple of the tabs and then drilled the middle hole to #40 in each tab. Next time out I'll move the tabs to the inside and prep them accordingly.
