Would do well as a 72% size for 13mm power probably.


You can definitely scale them up or down. Down's a little tougher because a lot of these paper models are in 1/144th scale. They're small to start with. I've done both this V2 and a Mercury Redstone at 3X, the Redstone flew beautifully in light winds with an E9 (catoed the original model at NARAM-51, but never any issues with its replacement).

For your model rocket parts: 18mm engine mount tube, thrust ring, & centering rings did you make your own from cardstock as well?


Regular BT-20 stuffer tube with foam board centering rings. The nose cone shoulder is cut out of 110 lb. cardstock, again with a couple of foamboard circles to shape it. There's a hunk of 1/4" balsa about 1" square glued to the foamboard to give the screw eye something to hold onto. I don't trust the foamboard for the stress at ejection, given the considerable noseweight I used.

These paper models are a lot of fun. It took me some time to figure out the best techniques for them, but once you've built 2 or 3 of them, they're a snap.

If you're interested in a PDF copy of a presentation I did several years ago at NIRCON, PM me your email address.
