Estes Antar #7310 Build, Part 5, Some Parts Prep

The launch lug is cut in two for two 1" long sections.
These lugs were made of stiff material and didn't crush when cut with a new razor blade. If the lugs feel like they are folding under pressure from the blade, you might want to slip in a dowel for support.


There are laser cut slots for the triangular part K detail pieces.
After looking at the complex mask, I decided to glue them in place and fill the cut lines.
The tab will be cut off the "K" pieces and glued on the wing after they have been painted. You'll have to mask a strip on the wing so the glue will stick.


As usual, the laser cut edges will have to be squared up with a block. This balsa is 1/8" thick so the wedge cut of the laser is apparent. 
The molding seams on the nose cone are pretty clean.
First, sand the high seams.
Here I've marked the low recess seam areas with pencil. The seams got a bead of medium super glue and was allowed to dry. A filler bead of CA will take quite a while to dry. Set the nose cone horizontal while drying so the glue can't run.
Sand the raised glue bead with 220 grit followed by 400 grit.

The trick to smoothing the seams on a plastic nose cone is to keep the curvature round. You don't want to over sand and end up with flat sides.

  1. After looking over the instructions* and looking over the painting instructions, I better understand your rationale for keeping the "wing fence" (K parts) separate until most of the painting is complete. Not only do they get in the way on the masking for the wings, but these "wing fence" parts are painted deep forest on the inboard side and white on the outboard side. As they're not structural parts, the slotting isn't really required for strength, so mostly the slotting serves as a location guide for the part.

    * Aside from being convenient, being able to read the instructions before you have the kit makes it a bit more likely we'll read through the instructions completely *before* starting the build. Though consciously we *know* we should read the instructions (from start to finish) *before* we do anything, having the parts right in front of us unconsciously tempts us to "get started right away".
