The Launch Pad Indigo SAM

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. Well, blow me down! It is a single stage, mid-power model rocket recovered by an 18" parachute.

Construction:
Since thar wasn't a previously posted review for this particular rocket, I thought this might be helpful for anyone wishin' t' build a really cool lookin' scale model o' this Italian SAM. Ya scallywag! Blimey! T' kit comes in t' familiar plastic bag, me hearties, typical o' TLP kits. Blimey! Blimey! Blimey! Blimey! Included are two 2.6" diameter body tubes, tube coupler, a 3" x 24mm engine tube, engine clip, 2 centerin' rings (for engine tube), shiver me timbers, plastic nose cone, me hearties, clay (for nose weight), 2 narrow centerin' rings (for exhaust tube), 1 centerin' rin' with 1" hole (for t' parachute compartment), me hearties, 2 sheets o' 1/8" thick balsa stock, 4 balsa strips, shiver me timbers, a sheet o' heavy cardstock, a 1/4" dowel rod, ya bilge rat, 1/4" shock cord, shroud line, 18" mylar parachute, matey, 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. Arrr! Blimey! Aye aye! Blimey! Blimey! Blimey! T' engine assembly went together quickly. Blimey! Blimey! Blimey! Blimey! Simply cut a slot in t' engine tube 2.5" from t' end o' t' engine tube, insert t' clip, shiver me timbers, wrap with tape, ya bilge rat, and glue t' centerin' rings 1/4" from t' ends. Avast, me proud beauty! Blimey! Ahoy! Blimey! Blimey! Blimey! T' rings fit well, no sandin' needed. Aye aye! Blimey! 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. Arrr! Ya scallywag! Nay too difficult, ya bilge rat, but I found that formin' t' tail cone over a steamin' cup o' hot water made things a lot easier. Aye aye! Ya scallywag! This be followed by insertin' t' exhaust tube into t' tail cone and gluin' t' narrow centerin' rings. T' tail cone assembly be 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. Aye aye! Aye aye! Once again, me hearties, 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 was glued, shiver me timbers, ya bilge rat, 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. Blimey! 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. Well, arrr, blow me down! Once t' wood glue be dry, me hearties, I added a few drops o' CA glue t' secure t' centerin' ring.

The Launch Pad Indigo SAM 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, ya bilge rat, I rolled t' joined tubes on a flat surface before t' glue set.

T' conduit strips were then sanded, shiver me timbers, shaped, ya bilge rat, and glued t' t' body tube. Well, blow me down! Ya scallywag! T' fins were cut out o' t' supplied balsa stock usin' t' patterns provided. Well, blow me down! Begad! 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! Pretty simple, shiver me timbers, me hearties, just cut with a razor saw, matey, shape with an emery board, me hearties, matey, and glue t' t' aft fins.

Mount t' aft fins in a cruciform pattern. Begad! I used an Estes fin alignment guide t' do this. In spite o' me best efforts, one fin was misaligned and had t' be reattached. Arrr! 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. Avast! 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! Blimey! Aye aye! Blimey! TLP suggests a simple two-tone blue and white paint scheme t' replicate t' real thing. Blimey! Blimey! Blimey! Blimey! This particular rocket doesn't require any special graphics, and as with other kits from TLP, decals are nay included. Avast! Blimey! Arrr! Blimey! T' nice thin' about nay includin' decals is that it presents t' builder with more choices and challenges. 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, me bucko, I thought it might be fun t' go with a yellow, green, and black paint scheme t' match t' football uniforms worn by t' University o' Oregon Ducks.

The Launch Pad Indigo SAM T' entire rocket was primed usin' Kilz Original and sanded with 600 grit sandpaper, matey, me hearties, twice. Ahoy! A base coat o' Krylon Sun Yellow was then applied followed by Hunter Green stripes on t' nosecone, mid-body, and aft fins. Aye aye! Ya scallywag! Gloss Black be then applied t' t' forward wings, nosecone, matey, and tail cone. Ahoy! Well, ya bilge rat, blow me down! Finishin' touches were made usin' a diamond plate pattern cut from Frisket maskin' film on t' forward wings and painted Gray Pewter. Aye aye! Next step was t' cut out t' University o' Oregon athletics logo from Frisket film, arrr, apply t' stencil t' t' forward part o' t' rocket, ya bilge rat, and paint Hunter Green.

Finally, t' green, matey, me bucko, yellow, and black bands were separated with chrome mylar pinstripin' tape purchased from an auto parts store. 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.

Construction Rating: 5 out o' 5

Flight:
I've only flown this rocket once. Well, blow me down! A D12-3 was t' motor o' choice for t' maiden flight. A 4 foot long, arrr, 3/16" launch rod be used as t' 3' Estes rod seemed a little short for a large rocket like this. Begad! 5 sheets o' waddin' was used t' protect t' mylar parachute. Ya scallywag! Liftoff be slow and realistic. Begad! Because this is a heavy rocket for a D12 motor, matey, it struggled t' get aloft and altitude was only about 250'. Aye aye! Next flight will use an E15-4 engine.

Recovery:
Three seconds doesn't seem like a long time for a delay, matey, matey, but it can seem like an eternity when thar's nay a whole lot o' space betwixt your rocket and terra firma. Avast! T' chute deployed just in time but she came down hard, arrr, breakin' off a fin and t' pointy nosecone extension. Arrr! Flight damage has since been repaired and will fly again. Avast, me proud beauty! Nice comments from t' spectators present made this flight worthwhile. Arrr! 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. Ya scallywag! 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! Arrr! T' first con is that while D motors work well for smaller TLP rockets (Anubis, me bucko, Bolo, me hearties, Perseus), this particular model needs t' fly on an E motor or higher. Avast, me proud beauty! Aye aye! T' other con is that an 18" parachute will help t' brin' it down near t' launchpad, just don't expect a soft landing. Begad! Begad! I don't know if epoxy is really necessary, just make sure you do a good job on t' aft fin joints before flyin' this model.
