I was surprised that there are no reference guides on the PDFs to help compute the correct scale value when printing.
Yeah, an inch scale should have been included.
And clearer instructions.
I had some parts left over that weren't mentioned in the instructions.
Maybe because there were two options in building this.
Easy way = my build.
Craftsmans' build = metal film, tower built from dowels, 24mm motor mount.
Using standard 8 1/2 x 11 typing paper, printing from the pdf at actual size clipped some of the templates off the edge of the paper. Maybe A4 size would have worked, but didn't want to buy a whole ream of new cardstock for just one model.
And, as I mentioned earlier, how hard would it have been to include the orange in the pdf?
Actual LJ had orange rectangles, three fins with orange tips, one fin with one side orange and one side black, orange on the lower part of the boilerplate capsule, and black tower trusses and motor nozzles with an orange tower tank and black aerospike.
And the PDFs are just a low-res bitmap (scanned image) rather than actual vector line art, so the quality if not very good.
Here's a closeup, you be the judge:
Here's a look at the business end:
And a side by side comparison with the Enerjet LJ clone:
The Enerjet uses the Estes red plastic Mercury capsule and ST-20 tubing. It maidened on a BP E motor. A little bit of coning, but stable.
For the cardstock, since I couldn't do anything about the tower and nozzles being red, I sharpied the tower tank red also, to be consistent. Just need to finish up by sharpieing the lower capsule orange and clear coating. I might do a removeable aerospike.
