… on this build! (smile)

But first, a vital point: NEVER SAY ANY DEFINITIVE LAST WORDS.  Lest they pop up and bite you in the hind end.

Thus is the case after my big claim that the last large area of micro and epoxy wipes were a thing of the past on this build after I glassed the bottom winglet intersection fairings and micro’d them with the outboard underside of each wing.  Then when checking the right underside wing-to-aileron elevation I discovered the trailing edge of the wing, just forward of the bottom aileron forward edge, was way too high.

Over the ensuing days post this discovery, I spent over an hour each day sanding down the area forward of the aileron, which kept having to be feathered farther forward the lower I got at the trailing edge, which was essentially the original wing’s glass surface. I then micro’d up the entire area to get all the irregular lumps and elevations back smooth again.

Well, this morning I spent nearly 2 hours sanding the micro on both the bottom wing and aileron.

With the underside wing contoured and smooth, as well as the aileron, we’re back to having acceptably level and very closely matching elevations across the aft wing surface to the bottom surface of the aileron.

Next it was time to get the gap sorted out and with plans spec, which is 0.08″ min to 0.2″ max gap along the underside interface between aft wing edge and the front lower lip of the aileron (the rounded full length weight bar).  My taped popsicle stick is a little under 1/8″ thick, which with paint should put my gap at around 0.1″ +/- 0.015″.

To get the gap correct, unlike on the left side, this time I used the Dremel tool with a cutoff disk and over a half-dozen iterations to get the wing edge trimmed down to get the correct gap.  Then a few rounds of sanding and Voila!  Wing-to-aileron gap within plans specs.

With both the right wing-to-aileron elevation and gap looking good, I then epoxy wiped both the underside wing aft center area and the bottom of the right aileron with 4 total coats of raw West epoxy, with 206 slow hardener (I normally use 205 fast).

I then worked on my last official foam-covering layup on the aft end of the right winglet intersection fairing.  I first cleaned up the glass edges and then cut/sanded/cleaned the foam edges to create “flox” corners, but for weight I’ll be using micro (pic 1).

Since this is not a high stress area I simply used West epoxy to whip up some micro and apply it in the edge troughs and on the surface of the foam, both top and bottom (pic 2).

I then laid up a single ply of BID (pic 1) and then peel plied it (pic 2).

Although not critical for getting this bird in the air, but since I have access inside the outboard right strake with the wing off, I decided to go ahead and make up 2 each K1000-3 platenut assemblies to secure the right strake’s outboard underside video camera mount.

Here are the 2 K1000-3 platenut assemblies that I just assembled (pic 1), and then floxed (MGS 335) into the inside of the outboard right strake —after sanding the attach spots and hitting them with Acetone (pic 2).

And here we have the external side of the right bottom strake for the floxing in place of the K1000-3 platenut assemblies: bolts with grease applied, taped up camera mount base, with taped up wide area washers.

I then left my layup and floxing to cure overnight as I called it a night.
