I had been thinking of doing a level 3 build for a bit, and the opportunity arose to make it happen.* I have done scale rockets for my other cert flights (1/4 scale Patriot for Level 1 and 23% Black Brant VC for Level 2), so I had been considering what to do for Level 3.* After some decision making, the full scale Astrobee D won out.* 13' 2" of awesomeness awaits at the end.* Figured end weight should be around 50lbs empty.* Planning on aeropoxy products for laminating plywood fins and epoxy joints.


Basic drawing from OR attached, as is the av bay wiring diagram for the Raven, RRC2+ I plan on using.* More pictures to follow.

So the first part for the dry fit, I started with checking the centering rings I have knowing they're for a slightly different set of tubing than I have. They're 1/8" G10. So I turned the OD on all 3 to fit the 6" G12 I have for airframe. Then cut the center with a 4" hole saw for the motor mount.

Awesome information guys. The modeling of the antennas is something I'd like to do, but I was missing the drawings needed. Now I have them. Thank you, qquake2k.

I was planning on modeling the antennae, but never got around to it.
One of my friends is working on 3d printing them based on the drawings you had in your thread. Antenna base and the antenna screws into it.

I was going to use brass, but it ended up being too complex for my skills and tools.
 
Yeah, I've got some coming for those. I'll have extra, hence the idea, but my friend wants to test some things in his process and is offering to build the antennas.

I’m pleased to hear this project is a go!

I need a set of those in 2/3 scale. If your friend is interested in making them for me, give them my contact info.

Cheers,

I asked him about it, it's possible, but he's going to get through the full scale ones first, as he would need to rework how it's done for a smaller scale. But the ones hes doing will have a thread on antenna like the real ones.

I marked and drilled the Avbay plates which are 1/4" fiberglass with a machined ridge meant for an end cap of an Avbay.

While drilling the Avbay endplates I drilled the centering ring for the attachment for apogee shock cord. I used red locktite to keep them from backing off.

I cut out the avbay sled from 1/16 fiberglass and will need to pick up some clips I can use to lock it onto the allthread.
