Just had a couple of hours in the hangar today, so I knocked out the simple task of riveting the fiberglass tips on the horizontal stab. I questioned the build instructions here, because they don't call for any kind of doubler, just pull rivets right through the fiberglass. When I asked date question on VAF, I got the usual variety of opinions, but Scott McDaniels, who is a DAR and retired from Vans Prototype shop a couple of years ago responded that all the prototypes are built per print there and it's not a mistake, so I went with that and just riveted them on so that the bulb of the pulled end is pulled right up against nothing but fiberglass. In spite of my best efforts, the gap between the tip fairing and the elevator counterweight ended up the tiniest bit asymmetrical. It's not much, maybe 1/16" or so, and it's only noticeable if you sight straight down between the two with the elevators neutral, so it's not worth fixing, but it's a little annoying. On the plus side, from every other angle they two fairings blend symmetrically and look very nice. It's pretty exciting to see stuff like tis all coming together.
