Sorry, forgot to add photos before posting.

Wow, Rollos... whoda thunk it...

Looks great! Keep 'em comin'.

Moving along to the antenna support and the Asteroid-Meteoroid Detector.

I'm glad I decided to use the foil. I almost skipped it but think it brings this alive. Every picture or illustration hows a lightly different arrangement of the silver vs. gold foil so some of it is a best guess.

Trimmed out girder and bottom plate. Glued the girder to the plate by "walking" it around the round plate. The plate is double-thick illustration board.

There's an upper plate that a shallow cone attached to. Built those up as directions showed - simple.
I believe the entire cone of the antenna shoul be one piece, but in this model it's been broken up between the large piece (see post #1) and this smaller cone. When the parts are glued in place, it will look like one cone resting on the support. If I'd studied the directions and the pieces longer, I might have built this differently but it's no real matter. Built up the top plate and shallow cone, glued rtogether. After that glue dried, I mounted the top plate by fitting it inside the ring formed by the girder. This gives it much strength and helps hold the shape.
Before glueing to the Main Bus, I cross-sliced the area to be glued. #1 it's not necessary to glue the entire surface #2 it's harder to get a flat join.

I built the Asteroid-Meteoroid Detector as per the instructions. Inside the supports, I glued in wire pieces for strength. The wire protrudes from the ends of the supports and stick into the Main Bus. Used CA glue to attach.

Thanks!

Don't forget the "license plate." Near as I can tell, it mounts outside the circular truss structure below the HGA facing inward.

Thanks Yogi, will inclde.

Great job so far! I need to detail my own model like this. With inspiration, from you, I just may get to it someday.
Here's another picture detailing the plaque placement. Just like Yogi showed, the graphics face inward (apparently this was done to protect the etching from the erosion of interstellar dust over the eons). The backside is blank. The actual plaque is gold-anodized aluminum, so it should have a gold tint to it.

Excellent photo, thanks! See places where I can add some more detail.
The little blocks on the rear of the HG antenna do have some subtle detail on them and the "straps" on the rear of the antenna also.

As with other frames, internal wire bracing is my friend here.
Cut and bent the lengths, used CA glue to tack in place. Left a little sticking out the ends to push into the Main Bus for strength.
Folded and PVA glued shut.
Trimmed out
Covered with gold foil (I'm keeping Rolo's popular).
Poked tiny holes in the Main Bus, inserted the wire and CA glued in place.
I'll touch up the joins later.

The title says it all...wphew, what a mouthful!

These are the two structures that stick out from the sides of the craft. I presume so any stray radiation does not affect the on-board instruments.

I've seen the fins straight, notched, split, etc. I notched them for this model.

I'd been avoiding these as they looked difficult to build but so far they've been easy. I now think the attachment to the craft will be the hard part. I'll paint white when they're together and the glue has dried.

At this scale, the part rolled around a AA battery quite nicely!
