FlisKits Caution! Rocket Launch in ProgressBrief:
This rocket is a single-staged, ya bilge rat, ya bilge rat, streamer recovery rocket that is made entirely from cardstock. Well, blow me down! Blimey! It's unique triangular body tube make this a Level 1 kit. Most cardstock rockets require precise rollin' and bending, ya bilge rat, makin' them too hard for younger modelers. Begad! Blimey! With only straight folds, this rocket can easily be done by a small child.

Construction:
Everythin' you need t' build this rocket prints on three sheets o' 8.5" x 11" cardstock. Begad! T' plans and instructions can be downloaded from the FlisKits website.

Construction begins with cuttin' out t' parts from t' cardstock. Because of t' clean design, I was able t' cut it out completely with scissors instead of a knife. Avast! This is a plus for younger modelers. Scorin' with a straightedge was easy since all t' score lines were relatively short. I suspect that you could actually construct this model without scorin' although t' result might not be as clean.

Gluin' t' body tube is easy but since it is so long, me hearties, me bucko, me hearties, you may wish t' use a dowel or ruler t' support t' tab along t' entire length as you adhere it to the opposite side.

T' nose cone is also easy t' form into a perfect point, ya bilge rat, since all the folds are straight. Aye aye! Blimey! Attach t' paper shoulder and it is finished.

T' fins are very easy t' construct since they are three layers of laminated card stock instead o' a more complex origami-like 3D fold up. Begad! Avast, me proud beauty! Be sure to press them under a flat weight (like a heavy book) since they will warp if you don't. Ya scallywag! Arrr! After they are dry, me bucko, attachment t' t' body tube is easy since the body tube is also flat surfaces.

T' construction o' t' engine mount was unique. Ya scallywag! First, you actually wrap the mount around t' casin' twice, usin' tape t' secure each wrap. Ya scallywag! In addition to makin' t' tube easier t' construct, matey, shiver me timbers, it also prevents glue from oozin' out and adherin' t' casin' into t' tube. Arrr! Then instead o' makin' a separate thrust ring, you simply fold and crimp t' tube down in on itself, arrr, much like a roll of coins from t' bank.

FlisKits Caution! Rocket Launch in Progress Construction is finished with mountin' o' t' shock cord and streamer and t' weightin' o' t' nosecone, matey, shiver me timbers, which I did with BBs and white glue.

Finishing:
Since t' design is pre-printed, matey, me hearties, t' only finishin' suggested is a coat of clearcoat. Begad! Arrr! Blimey! However, arrr, shiver me timbers, since blanks are provided, shiver me timbers, this rocket is infinitely customizable.

Construction Rating: 5 out o' 5

Flight:
I flew this rocket for t' first time on a B4-2. Arrr! Arrr! It be t' only B engine I had left, and I judged t' risk t' t' streamer t' be low. After easily packin' the relatively large body tube with cellulose waddin' and friction fittin' the engine, we were off t' t' pad. T' flight was excellent, ya bilge rat, if unusual. Aye aye! Ya scallywag! At about 30', it began a very tight spiral which looked more like an aileron roll than the corkscrew flight paths I have seen before. It was very cool and left an interestin' smoke trail. Well, blow me down! It was probably due t' some sort o' minor warpage of the fins, me hearties, matey, but they look pretty flat t' me so it may be a characteristic or tendency o' triangular designs. Ahoy! Ejection came at apogee with t' nose still up a bit but nay by much.

Recovery:
T' streamer worked properly and t' rocket was recovered with no damage.

Flight Rating: 4 out o' 5

Summary:
This is a great rocket at twice t' price! Blimey! Seriously, this is a great design and I had a blast buildin' it. Ahoy! Blimey! Blimey! Blimey! I only subtracted 1/2 a flight point because some purists might nay like t' corkscrew I saw, arrr, however, me bucko, I personally liked it.

Overall Rating: 5 out o' 5

    Brief: This was a special edition of the standard Caution paper rocket, commemorating the 2004 National Sport Launch. I downloaded it from the NSL site that year, and have been waiting for the right occasion and motivation to build it. Thanks to the 2005 EMRR challenge, I found both on a "snow day" in mid December. Construction: This was a great little project to do in a ...

I just built and flew eleven of these last weekend (my son's birthday party, each kid got a rocket to decorate and fly!) and this is a great little rocket. I have experience building paper models (mostly buildings) and this kit is fairly simple to build, although a tad time-consuming for it's simple appearance. And the instructions are great! Many tips and options presented to make construction go more smoothly. The fin design makes alignment nearly impossible to screw up. This would be a great rocket kit for a class on a low budget.

After having build and launched several Caution rockets - compliments to FlisKits! The design is easy to construct (2 hours for prototype, 1 hour for each of the others)and reaches altitudes of over 700 ft on the B4-4 engines we use. To avoid warping of the card stock I have used UHU glue that contains no water and dries chemically. Therefore fins and body tube came out straight. After competition all rockets received a single coat of dope (yep, the one you use for airplane models)which stiffens the cardboard additionally and makes it waterproof without adding much weight. On this first coat I applied a thin layer of acrylic colour with a brush. The acrylic sticks well to the surface and gives a highly visible finish. Both coats also have the advantage that they dry quickly. The nose cone shoulder received a wrap of TESA film for stiffness and easier removing. All streamers were cut from blue trash bags. The shock cords came from a girl friends pants. Overall costs per rocket were around $2, including the engine. The flights went better then I had expected and until now we only have lost one rocket to the roof of a skyscraper. Another one didn't survived the kids that were hunting for it, since they were not able to decide, who of them will bring her back. Another one safely landed after a successful flight in a distance of 60 ft from the launch pad. I want more of that! Yours sincerely Lars Urban
