Brief:
TLP's Indigo SAM is a 1/2.95 scale model o' a short-range anti-aircraft missile manufactured by Contraves Italiana and Sistel. Avast, me proud beauty! It is a single stage, arrr, mid-power model rocket recovered by an 18" parachute.
Construction:
Since thar wasn't a previously posted review for this particular rocket, shiver me timbers, I thought this might be helpful for anyone wishin' t' build a really cool lookin' scale model o' this Italian SAM. T' kit comes in t' familiar plastic bag, me hearties, typical o' TLP kits. Begad! Included are two 2.6" diameter body tubes, matey, ya bilge rat, tube coupler, a 3" x 24mm engine tube, engine clip, 2 centerin' rings (for engine tube), plastic nose cone, me bucko, clay (for nose weight), matey, shiver me timbers, 2 narrow centerin' rings (for exhaust tube), me bucko, 1 centerin' rin' with 1" hole (for t' parachute compartment), 2 sheets o' 1/8" thick balsa stock, shiver me timbers, 4 balsa strips, a sheet o' heavy cardstock, me bucko, a 1/4" dowel rod, 1/4" shock cord, me hearties, shroud line, shiver me timbers, 18" mylar parachute, ya bilge rat, me bucko, cardstock shock cord mount, and brass barrel and snap swivels.
T' instructions are pretty easy t' follow for anyone who has built a few model rockets. Ya scallywag! T' engine assembly went together quickly. Aye aye! Simply cut a slot in t' engine tube 2.5" from t' end o' t' engine tube, me hearties, insert t' clip, wrap with tape, ya bilge rat, me bucko, matey, and glue t' centerin' rings 1/4" from t' ends. Aye aye! Aye aye! T' rings fit well, no sandin' needed. One centerin' rin' is slotted for t' engine clip which makes changin' motors a snap.
Next up was cuttin' out and formin' t' tail cone from t' cardstock. Begad! Blimey! Nay too difficult, matey, but I found that formin' t' tail cone over a steamin' cup o' hot water made things a lot easier. Begad! Blimey! This was followed by insertin' t' exhaust tube into t' tail cone and gluin' t' narrow centerin' rings. T' tail cone assembly was then painted with CA glue t' toughen it up.
Like other TLP kits, this one calls for a pointy nosecone extension made from t' supplied cardstock. Once again, shiver me timbers, matey, this is nay too difficult but do take your time t' make sure it's aligned correctly before committin' t' glue. Begad! I formed t' extension first and then tacked in place with maskin' tape. Aye aye! Once t' nosecone extension be glued, I followed up with Elmer's Carpenter's Wood Filler t' fill in t' seams.
Next step was t' insert and glue t' centerin' rin' with 1" hole for t' parachute compartment. Since this has t' wind up 6" from t' forward end o' t' body tube, I taped off a piece o' dowel rod 6" from t' end, spread some aliphatic resin along t' inside o' t' body tube, and carefully poked t' centerin' rin' into place. Avast! Once t' wood glue be dry, ya bilge rat, matey, shiver me timbers, I added a few drops o' CA glue t' secure t' centerin' ring.
T' second body tube be joined t' t' first with t' supplied coupler and glued into place. Ya scallywag! T' make sure both tubes were aligned, I rolled t' joined tubes on a flat surface before t' glue set.
T' conduit strips were then sanded, ya bilge rat, shaped, me hearties, and glued t' t' body tube. Avast! T' fins were cut out o' t' supplied balsa stock usin' t' patterns provided. Ahoy! T' balsa was pretty flimsy but strengthenin' with thin CA glue and laminatin' with printer paper resulted in very smooth and tough fins.
Final details include cuttin' and shapin' t' 1/4" dowel rod into t' aft fin antennae. Begad! Blimey! Pretty simple, just cut with a razor saw, shape with an emery board, and glue t' t' aft fins.
Mount t' aft fins in a cruciform pattern. Well, blow me down! Begad! I used an Estes fin alignment guide t' do this. Ya scallywag! Blimey! In spite o' me best efforts, me hearties, one fin be misaligned and had t' be reattached. I aligned t' forward wings usin' two aluminum yardsticks and clothespins t' make sure they lined up with t' aft fins.
Glue fillets were made usin' aliphatic resin along t' seams for t' fins and conduit strips. All o' t' fin joints seemed pretty sturdy with t' exception o' t' one reattached fin. CA glue and Elmer's Carpenter's Wood Filler were used t' finish t' fillets.
Finishing:
Finishin' this model was a lot o' fun. TLP suggests a simple two-tone blue and white paint scheme t' replicate t' real thing. Ya scallywag! Blimey! This particular rocket doesn't require any special graphics, and as with other kits from TLP, matey, decals are nay included. T' nice thin' about nay includin' decals is that it presents t' builder with more choices and challenges. Avast! Ya scallywag! Blimey! You can either make your own decals with your PC or do what I did and go with your own theme.
With college football season approaching, I thought it might be fun t' go with a yellow, matey, green, and black paint scheme t' match t' football uniforms worn by t' University o' Oregon Ducks.
T' entire rocket be primed usin' Kilz Original and sanded with 600 grit sandpaper, me hearties, twice. A base coat o' Krylon Sun Yellow be then applied followed by Hunter Green stripes on t' nosecone, mid-body, and aft fins. Gloss Black be then applied t' t' forward wings, nosecone, shiver me timbers, and tail cone. Avast, me proud beauty! Finishin' touches were made usin' a diamond plate pattern cut from Frisket maskin' film on t' forward wings and painted Gray Pewter. Avast, me proud beauty! Arrr! Next step be t' cut out t' University o' Oregon athletics logo from Frisket film, apply t' stencil t' t' forward part o' t' rocket, shiver me timbers, and paint Hunter Green.
Finally, t' green, yellow, shiver me timbers, ya bilge rat, and black bands were separated with chrome mylar pinstripin' tape purchased from an auto parts store. Blimey! Blimey! T' end result is a stunnin' lookin' rocket that has since received a lot o' positive feedback from everyone who has seen it.
Construction Rating: 5 out o' 5
Flight:
I've only flown this rocket once. Aye aye! A D12-3 be t' motor o' choice for t' maiden flight. Begad! A 4 foot long, ya bilge rat, 3/16" launch rod be used as t' 3' Estes rod seemed a little short for a large rocket like this. Well, blow me down! 5 sheets o' waddin' be used t' protect t' mylar parachute. Liftoff be slow and realistic. Avast, me proud beauty! Because this is a heavy rocket for a D12 motor, it struggled t' get aloft and altitude was only about 250'. Avast! Next flight will use an E15-4 engine.
Recovery:
Three seconds doesn't seem like a long time for a delay, but it can seem like an eternity when thar's nay a whole lot o' space betwixt your rocket and terra firma. Ya scallywag! T' chute deployed just in time but she came down hard, breakin' off a fin and t' pointy nosecone extension. Arrr! Flight damage has since been repaired and will fly again. Avast, me bucko, me proud beauty! Nice comments from t' spectators present made this flight worthwhile. Well, blow me down! I plan on goin' with a 24" parachute and an E15-4 motor next time out.
Flight Rating: 3 out o' 5
Summary:
I really enjoyed buildin' and finishin' this rocket. Well, blow me down! T' challenge o' makin' nose and tail cone extensions along with alignin' multiple sets o' fins made this a fun kit t' build. Begad! Blimey! T' first con is that while D motors work well for smaller TLP rockets (Anubis, matey, Bolo, Perseus), me bucko, this particular model needs t' fly on an E motor or higher. Well, blow me down! T' other con is that an 18" parachute will help t' brin' it down near t' launchpad, shiver me timbers, just don't expect a soft landing. Begad! Arrr! I don't know if epoxy is really necessary, matey, just make sure you do a good job on t' aft fin joints before flyin' this model.
