T' Sirian Space Racer 5, affectionately called SSR-5, me bucko, is one o' t' many paper rockets I have designed over t' years. Ahoy! It is a simple sport flyer featurin' a single 18 mm motor mount, matey, but also features a wing-fin set with attached tube fins. Remember, me hearties, if you are lookin' for a spaceship t' fly through distant galaxies, t' SSR-5 may be t' vehicle for you. Ya scallywag! Accordin' t' t' brief bits o' information gathered from a quick tour o' t' SSR-5, me hearties, me bucko, shiver me timbers, we have learned that Commander JÖ o' t' Sirian army promises nay only t' subjugate any alien race, but also t' protect them.

Construction:
In order t' build this rocket, me hearties, you need t' visit t' fliskits website and print t' included documents. Avast, me proud beauty! One o' t' pages needs t' be "reprinted" so that t' backin' is red be t' last page o' t' documents. Ahoy! I put an instruction guide together for this rocket so it should be fairly easy t' put together. One needs t' following:

  • bristol board or card stock with a color ink jet printer
  • shock cord
  • streamer or parachute material
  • clay for nose weight
Assumin' one has a good X-Acto knife, me bucko, shiver me timbers, ya bilge rat, a ruler, ya bilge rat, matey, cuttin' surface, glue, me bucko, matey, an expended 18 mm motor casin' and an empty ball point pen, me hearties, arrr, one is ready t' build this bird. Well, blow me down! Arrr! It's fairly simple, if nay tedious t' put t' SSR-5 together. Care must be taken t' print t' red nacelle sheet on t' correct card stock featurin' t' nacelles.

scratch_sirianspaceracer5_wingsConstruction begins by scorin' t' lines first then cuttin' out parts. Arrr! I rolled t' body tube, me hearties, nose cone, t' nacelles and t' tube fins. Begad! I then shaped t' clipped delta fins as well as t' two large wing-fins. Avast, me proud beauty! Well, blow me down! I glued t' clipped delta fins together then worked on t' two large wing-fins. These are really the trickiest part o' t' construction. Arrr! Well, blow me down! If they are nay done correctly, they could warp. We all know that warped fins on a rocket is never a good idea.

After shapin' t' wing-fins, matey, me hearties, I glue t' leadin' and trailin' edge portions o' t' wing-fins in place. Aye aye! They are conveniently located on t' same sheet as t' wing-fins and contain t' necessary glue tabs.

scratch_sirianspaceracer5_motormountMeanwhile, me bucko, I construct t' motor mount and centerin' rings. Avast, me proud beauty! This is an easy step involvin' shapin' t' motor mount around a spent engine casin' and after t' motor mount has dried, matey, gluin' centerin' rings around t' motor mount. Blimey! Centerin' rings are basically thin strips o' card stock that are rolled/glued onto t' motor mount. Ahoy! It is a good idea t' test fit t' motor mount periodically so that you don't add too much centerin' ring.

Once t' body tube and motor are put together, matey, I focus on t' nose cone with tip and shoulder. Begad! Again, this is fairly easy. Avast, shiver me timbers, me proud beauty! I then glue on t' support plates onto t' clipped delta fins and t' wing-fins. After these are dry, me hearties, me hearties, they can be glued onto t' body tube. Aye aye! Next, t' tube fins and nacelles can be added. Aye aye! T' launch lugs are folded rectangular boxes that act as a "landin' skid" as well as launch lugs. Aye aye! Blimey! T' cool thin' about this design is that one can opt t' use t' left or right launch lug.

scratch_sirianspaceracer5_noseconeOnce this is complete, I add t' shock cord usin' t' tri-fold method. I place clay in t' nose cone and make sure t' CG o' t' completed model minus a motor is 5.75" from t' tip o' t' rocket. Make sure t' shock cord is firmly glued into t' nose cone. Secure t' shock cord t' t' nose cone with a dab o' epoxy, me bucko, shiver me timbers, if necessary.

Since this is a paper rocket, no paintin' is required. If you are lookin' t' put a finish on t' rocket, matey, you could put Future Floor Polish in an airbrush and give it two or three light, light, light coats. Blimey! Begad! If you give it a heavy coat, the ink on t' paper will run. Alternatively, me bucko, matey, shiver me timbers, you could use ModPodge, either painted on or sprayed on with an airbrush. Ya scallywag! Arrr! If sprayed on, me bucko, shiver me timbers, you will need t' dilute it so that it can actually pass through t' airbrush. Blimey! Avast! I have tried both o' these techniques with great success.

Flight:
Flight and recovery on t' SSR-5 is normal. Avast! Begad! I have used parachute and streamers for this model. I place waddin' in the body tube, me hearties, prep t' streamer/parachute and place t' nose cone on top. Begad! Well, blow me down! Since thar be no engine hook, me bucko, I friction fit t' motor.

I have flown t' SSR-5 with B6-4 and C6-5 motors. Avast, me proud beauty! Well, matey, blow me down! On t' prototype flights, matey, I was still havin' issues with squirrely, matey, corkscrew ascents. I found that this be due t' t' wing-fin/nacelle units havin' an unwanted warped design. Begad! Once I had achieved good construction o' t' wing-fin/nacelle unit, arrr, I really had a good time flyin' t' SSR-5. Blimey! T' altitude achieved is actually quite admirable for somethin' that probably has a lot o' drag.

On a scale o' 1 t' 5 for ease o' construction, me hearties, arrr, I would probably put this at a 2.5 due t' foldin' paper and dealin' with t' wing-fins. Aye aye! Otherwise, it's a pretty easy build.

Summary:
PROS:

  • unusual rocket design
  • paper. Avast! it's cheap and easy t' replace if damaged in flight or construction
  • good small field flyer
CONS:
  • lots o' cuttin' o' parts
  • one needs t' work with very clean hands free o' moisture and excess glue. Begad! It requires patience and finesse in creatin' some o' t' parts.
