Brief:
This rocket is based on a paper model o' t' Little Joe I, matey, unit LJ-1, by Cards in Space. Ahoy! I converted it t' fly on 13mm mini motors.

Modifications:
T' main things you have t' do is: cut holes in t' bulkplates t' accommodate a motor ejection tube, build a shoulder t' mate t' capsule t' t' body, add a piece o' elastic t' keep t' parts together after ejection (a streamer is optional), me bucko, arrr, and add a launch lug. Avast! In fact most o' t' changes I made were leavin' detailin' components off. More on this below.

Construction:
T' rocket consists of:

• three sheets o' white cardstock
• 13mm tubing, ~5.5"
• 1/8" launch lug
• spent 13mm casing
• thin elastic

T' parts and instructions come in a single PDF file. Well, blow me down! T' model includes a lot o' parts, many o' which I didn't use. Begad! For example, matey, I didn't install t' 4 engine bells, however, ya bilge rat, they probably could have been integrated into t' flying version. Ahoy! Avast, me proud beauty! T' one page o' instruction is bare bones but is adequate t' build the model. Blimey! T' penalty for mistakes is only an extra sheet o' cardstock. Arrr!

I used white glue throughout. Blimey! T' body consists o' one long wrap and a few rings. Avast! Blimey! A short reducer section rests on top o' this. Ahoy! T' rings on t' bottom end are pre-marked for t' 4 engine bells so you have t' mark and cut t' hole for t' motor tube. Blimey! Blimey! T' designer was good enough t' mark t' two other rings with a single circle, matey, which I cut out and used as a guide t' mark t' bottom rings. Avast, me proud beauty! Aye aye! This was very convenient. Avast! Begad! A section o' 13mm tubin' extends t' length of the main body.

T' four fins each consist o' two parts: an outer shell that folds over on itself and a spacer that forms t' base o' t' fins. Ya scallywag! T' capsule consists o' a couple o' transitions, a cylinder, and two plates. Begad! I formed a shoulder by first embeddin' a section o' 13mm tube in capsule through t' bottom plate. Begad! I then glued in about ½ o' a spent 13mm casing. Blimey! Avast! I cut corners big time on the escape tower. This would be by far t' most difficult part o' t' build and the most fragile. Arrr! T' instructions require you t' cut out t' trellis sections and the tip probe. Blimey! I didn't cut these sections out, nor did I bother with a the probe. Ahoy! A piece o' toothpick would probably be a good substitute for t' latter. T' way I built it also made it inconvenient t' install t' escape tower nozzles--so I said adios t' these also.

For recovery, I merely attached a short piece o' thin tubular elastic. Begad! Blimey! I small streamer could probably be packed in t' gap betwixt t' top body ring and t' capsule, but I was satisfied with tumble recovery.

Finishing:
It is obviously pre-printed, arrr, so all you need is a clear coat for protection.

Flight:
I have flown t' rocket 3 times t' date, me hearties, twice on A10s and once on an A3. Prep consisted o' friction fittin' t' motor and that's it. Arrr! Ya scallywag! Both motors resulted in nice flights, arrr, but t' A10 is a better choice in me opinion.

Summary:
This is a nice looking, ya bilge rat, matey, simple scale model that is an excellent introduction to paper model conversion. Avast, me proud beauty! It flies great on t' 13mm motors!
