I thought I was done with paper rockets for a while after doing three recently. But my curiosity got the better of me and so I built the first one:
This is the 1904 rocket. Some observations:
1. Instructions are in Japanese, but if you've done cardstock rockets or models before, you can just follow the illustrations and figure it out.
2. Print in landscape mode, actual size, and use A4 or legal cardstock. I used letter sized cardstock, fit to paper and it seems to print slightly underscale. So I subbed a bt-20 tube for the paper engine tube and enlarged the hole in the centering rings using a circle cutter.
3. The instructions include making an engine hook out of wire. I just subbed one from my parts stash.
4. The interlocking glue tabs are interesting. Haven't seen that before.
5. The fins are open on the bottom, and I'm concerned about landing damage. So I used a generic "choose your size" chute kit and chose 24". the largest size. Slowest descent, but the most wind drift. Will fly on calm days only.
6. No mention of nose weight, but my mindsim tells me that it might need some. Will see where the CG is after finishing.
Haven't decided yet whether to print the Camui on letter cardstock or look for some legal sized sheets. I may also redo the 1904 on legal paper. Hey, for a few cents of paper I can afford a redo, right?
The C75B rocket however is big. The actual size printout won't even fit on legal paper. You need ledger size (11X17). 24mm motor mount. Don't know if I'm gonna do that one.
There is also a .pdf for a paper launch controller. Interesting. Laters.
