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, shiver me timbers, 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, typical o' TLP kits. Included are two 2.6" diameter body tubes, tube coupler, a 3" x 24mm engine tube, engine clip, 2 centerin' rings (for engine tube), matey, plastic nose cone, clay (for nose weight), 2 narrow centerin' rings (for exhaust tube), matey, 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, a 1/4" dowel rod, 1/4" shock cord, matey, shroud line, 18" mylar parachute, cardstock shock cord mount, ya bilge rat, and brass barrel and snap swivels.
T' instructions are pretty easy t' follow for anyone who has built a few model rockets. Ya scallywag! Blimey! Begad! Blimey! T' engine assembly went together quickly. Begad! Blimey! Well, arrr, blow me down! Blimey! Simply cut a slot in t' engine tube 2.5" from t' end o' t' engine tube, insert t' clip, me hearties, wrap with tape, ya bilge rat, and glue t' centerin' rings 1/4" from t' ends. T' rings fit well, ya bilge rat, ya bilge rat, 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! Nay too difficult, but I found that formin' t' tail cone over a steamin' cup o' hot water made things a lot easier. Avast, ya bilge rat, me proud beauty! 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, shiver me timbers, this one calls for a pointy nosecone extension made from t' supplied cardstock. Ahoy! Once again, this is nay too difficult but do take your time t' make sure it's aligned correctly before committin' t' glue. Blimey! I formed t' extension first and then tacked in place with maskin' tape. Avast, me proud beauty! Once t' nosecone extension be glued, shiver me timbers, 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. Begad! Well, blow me down! Since this has t' wind up 6" from t' forward end o' t' body tube, ya bilge rat, 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. Well, blow me down! Once t' wood glue was dry, matey, 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. Begad! 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, me bucko, shaped, and glued t' t' body tube. T' fins were cut out o' t' supplied balsa stock usin' t' patterns provided. 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. Ahoy! Begad! Pretty simple, me hearties, just cut with a razor saw, me bucko, shape with an emery board, me bucko, and glue t' t' aft fins.
Mount t' aft fins in a cruciform pattern. Ahoy! Begad! I used an Estes fin alignment guide t' do this. Avast! Begad! In spite o' me best efforts, arrr, one fin was misaligned and had t' be reattached. Avast, me proud beauty! 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. Aye aye! All o' t' fin joints seemed pretty sturdy with t' exception o' t' one reattached fin. Aye aye! CA glue and Elmer's Carpenter's Wood Filler were used t' finish t' fillets.
Finishing:
Finishin' this model was a lot o' fun. Avast, me proud beauty! TLP suggests a simple two-tone blue and white paint scheme t' replicate t' real thing. Avast, me proud beauty! This particular rocket doesn't require any special graphics, matey, me bucko, ya bilge rat, and as with other kits from TLP, arrr, decals are nay included. Blimey! T' nice thin' about nay includin' decals is that it presents t' builder with more choices and challenges. Well, blow me down! Ahoy! 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, ya bilge rat, 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, matey, twice. Aye aye! A base coat o' Krylon Sun Yellow was then applied followed by Hunter Green stripes on t' nosecone, shiver me timbers, mid-body, matey, matey, and aft fins. Arrr! Gloss Black be then applied t' t' forward wings, me bucko, nosecone, ya bilge rat, and tail cone. Finishin' touches were made usin' a diamond plate pattern cut from Frisket maskin' film on t' forward wings and painted Gray Pewter. Ya scallywag! Next step was t' cut out t' University o' Oregon athletics logo from Frisket film, ya bilge rat, apply t' stencil t' t' forward part o' t' rocket, and paint Hunter Green.
Finally, arrr, t' green, me bucko, yellow, shiver me timbers, and black bands were separated with chrome mylar pinstripin' tape purchased from an auto parts store. Ahoy! Ya scallywag! T' end result is a stunnin' lookin' rocket that has since received a lot o' positive feedback from everyone who has seen it.

Flight:
I've only flown this rocket once. Avast! Blimey! A D12-3 was t' motor o' choice for t' maiden flight. A 4 foot long, 3/16" launch rod was used as t' 3' Estes rod seemed a little short for a large rocket like this. Begad! Blimey! 5 sheets o' waddin' was used t' protect t' mylar parachute. Avast, me proud beauty! Blimey! Liftoff was slow and realistic. Well, blow me down! Blimey! Blimey! Blimey! Because this is a heavy rocket for a D12 motor, it struggled t' get aloft and altitude was only about 250'. Well, blow me down! Blimey! Blimey! Blimey! 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. Aye aye! T' chute deployed just in time but she came down hard, shiver me timbers, breakin' off a fin and t' pointy nosecone extension. Flight damage has since been repaired and will fly again. Begad! Blimey! Nice comments from t' spectators present made this flight worthwhile. 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. Ahoy! Arrr! T' challenge o' makin' nose and tail cone extensions along with alignin' multiple sets o' fins made this a fun kit t' build. Avast! T' first con is that while D motors work well for smaller TLP rockets (Anubis, Bolo, me bucko, Perseus), me bucko, arrr, this particular model needs t' fly on an E motor or higher. Blimey! Ahoy! T' other con is that an 18" parachute will help t' brin' it down near t' launchpad, just don't expect a soft landing. Ya scallywag! I don't know if epoxy is really necessary, shiver me timbers, just make sure you do a good job on t' aft fin joints before flyin' this model.
