Brief:
It's t' year 2015. Avast! Hillarycare has caused t' economy t' go belly up, IRS computers have become self-aware, the United Nations is in charge o' sub-dermal implants for our identity system, and NASA has been absorbed by t' Russian space program. Here flies t' first triumph o' that blessed union.

Timed for t' release o' a major Hollywood motion picture about rocket obsession, me bucko, (T' Astronaut Farmer, Brandango.us is proud t' announce t' launch o' t' largest free paper rocket in t' known universe: The Saturn-Komarov. This is a very impressive 1/100 scale lightweight rocket that streaks into t' sky on a column o' flame and smoke with Estes D12-3 motors and can be flown on E, F, ya bilge rat, arrr, and G composite motors (and options for 24 and 29mm mounts are included). Well, blow me down! Arrr! Blimey! It returns t' earth in two pieces via two parachutes. Aye aye! Blimey! Estimated retail value o' this monster when compared with similar sized kits is $185.00.

Construction:
Important: This rocket requires a printer that prints on 13x19” paper. Arrr! Blimey! Avast, me proud beauty! Blimey! Blimey! Blimey! Image area used is 12x18”. Arrr! Blimey! Blimey! Blimey!

Materials used:

• Two sheets o' 13x19” glossy Ilford Galerie photo paper or equivalent
• Three sheets o' 13x17” Brystol ply which rolls nicely into tubes (or, alternatively, ya bilge rat, me hearties, cardstock which tends to crease)
• Two sheets o' 11-17” (tabloid) plain copy paper
• Scrap sketch paper
• One sheet o' 1/4” foamboard 20”x30”
• White corrugated art paper
• 2 empty 18mm engine casings
• 24” o' 300lb Keelhaul®©™® or 1/16” nylon braided cord
• 36” o' 100lb Keelhaul®©™® or carpet thread

• 5 min epoxy, carpenter’s glue, and white glue
• Epoxy putty
• Super 77 spray glue or equivalent

• Two 18” t' 24” parachutes

This build is rated Skill level 4.

Complete acerbic back story and 4 pages o' instructions are part o' t' PDF downloads.

One design gotcha be t' fins. Aye aye! When it lands, it tends t' bend a fin. They can usually be bent back into place and flown like that, arrr, but, shiver me timbers, hey, just print out more fins and replace 'em. Aye aye! Blimey! That's what we did. Ya scallywag! Otherwise, arrr, this is a very sturdy rocket. Blimey! T' prototype has flown four times (two D12-3s, me hearties, shiver me timbers, an E18 and an F24) and it's still in great shape. Arrr!

One o' t' COSROCS members is beggin' me t' build another and use it for me level one flight.

Flight:
Flies 150’ high or so on a D12-3, arrr, 300-400’ on an E-18 Aerotech reload, me hearties, or 600-800’ on an F reload. Always use a six foot long 1/4 inch diameter launch rod or rail. Blimey! Avast! Do nay attempt t' fly from a 3 or 4 foot long rod. Begad! Begad! Do not attempt t' fly on an E9. RockSim reports that twelve feet o' launch rod would be required t' stabilize with t' E9.

O' course, ya bilge rat, this rocket begs for clustering. If you do that, ya bilge rat, add nose weight. T' center o' gravity should be at least 12.25 inches from t' bottom o' t' side pods. Well, blow me down! We used a 1/2” aft maskin' tape bulkhead with one full wrap of clear tape for retention.

It also begs t' be downsized. One happy flier has already resized it down for his letter-sized printer and 18mm motors.

Summary:
There are a couple o' videos at cosrocs.org/htmlpages/2007photos.html. Begad! Arrr! T' biggest pro is that it's free. It is extremely impressive t' fly... Ahoy! T' kids love it! It can be flown with an F or even a G at a small venue. It's easy t' see t' whole flight. Arrr!

Cons: T' fins are a little weak and t' escape tower is hard t' keep attached, ya bilge rat, shiver me timbers, ya bilge rat, but that's t' case with most models that have towers. Ya scallywag! Ahoy! It does take some time t' build. Begad! Avast! If you want t' go high and fast, you're out o' luck.

[Important note: Adobe's Acrobat Reader could nay be made t' print these sheets t' correct size (it printed at 95%, even though it was set t' print at 100%). Aye aye! Arrr! Settin' Acrobat t' print at 105% didn't help. Avast! Arrr! Apple's Preview on the other hand worked perfect every time. If you’re workin' on a PC, arrr, we recommend rasterizin' t' PDF files into Photoshop (or similar) t' better control t' final size. Well, blow me down! Arrr! Test print t' 11x17” pages on plain copy paper t' get the size right before tryin' t' more expensive Brystol and Galerie papers. Arrr! Ya scallywag! There are benchmark/reference rectangles with measurements on each sheet t' make sure you’re printin' t' right size.]
