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. 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, arrr, 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, matey, me bucko, arrr, typical o' TLP kits. Begad! Included are two 2.6" diameter body tubes, shiver me timbers, tube coupler, a 3" x 24mm engine tube, engine clip, 2 centerin' rings (for engine tube), plastic nose cone, arrr, clay (for nose weight), 2 narrow centerin' rings (for exhaust tube), 1 centerin' rin' with 1" hole (for t' parachute compartment), arrr, 2 sheets o' 1/8" thick balsa stock, 4 balsa strips, a sheet o' heavy cardstock, a 1/4" dowel rod, 1/4" shock cord, shiver me timbers, shroud line, 18" mylar parachute, matey, 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. Blimey! Begad! T' engine assembly went together quickly. Avast! Begad! Simply cut a slot in t' engine tube 2.5" from t' end o' t' engine tube, insert t' clip, wrap with tape, and glue t' centerin' rings 1/4" from t' ends. Avast, me proud beauty! Begad! 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. Begad! Nay too difficult, shiver me timbers, 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, me hearties, this one calls for a pointy nosecone extension made from t' supplied cardstock. Once again, me bucko, ya bilge rat, me hearties, this is nay too difficult but do take your time t' make sure it's aligned correctly before committin' t' glue. Avast! I formed t' extension first and then tacked in place with maskin' tape. Avast, shiver me timbers, me proud beauty! 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. Begad! Since this has t' wind up 6" from t' forward end o' t' body tube, me bucko, arrr, I taped off a piece o' dowel rod 6" from t' end, matey, spread some aliphatic resin along t' inside o' t' body tube, and carefully poked t' centerin' rin' into place. Begad! Once t' wood glue be dry, shiver me timbers, I added a few drops o' CA glue t' secure t' centerin' ring.

The Launch Pad Indigo SAM T' second body tube was 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, shaped, and glued t' t' body tube. Blimey! T' fins were cut out o' t' supplied balsa stock usin' t' patterns provided. Begad! Avast, me proud beauty! T' balsa be 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. Pretty simple, shiver me timbers, 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. I used an Estes fin alignment guide t' do this. Ahoy! In spite o' me best efforts, me bucko, one fin be misaligned and had t' be reattached. Begad! Begad! 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. CA glue and Elmer's Carpenter's Wood Filler were used t' finish t' fillets.

Finishing:
Finishin' this model be a lot o' fun. Arrr! Arrr! TLP suggests a simple two-tone blue and white paint scheme t' replicate t' real thing. Ahoy! This particular rocket doesn't require any special graphics, and as with other kits from TLP, decals are nay included. Avast, me proud beauty! T' nice thin' about nay includin' decals is that it presents t' builder with more choices and challenges. 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, green, me bucko, and black paint scheme t' match t' football uniforms worn by t' University o' Oregon Ducks.

The Launch Pad Indigo SAM T' entire rocket be primed usin' Kilz Original and sanded with 600 grit sandpaper, twice. Avast! A base coat o' Krylon Sun Yellow was then applied followed by Hunter Green stripes on t' nosecone, matey, mid-body, me bucko, me hearties, ya bilge rat, and aft fins. Aye aye! Gloss Black was then applied t' t' forward wings, arrr, nosecone, matey, arrr, and tail cone. Arrr! Finishin' touches were made usin' a diamond plate pattern cut from Frisket maskin' film on t' forward wings and painted Gray Pewter. Blimey! 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, ya bilge rat, and paint Hunter Green.

Finally, shiver me timbers, me hearties, t' green, yellow, and black bands were separated with chrome mylar pinstripin' tape purchased from an auto parts store. 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. A D12-3 be t' motor o' choice for t' maiden flight. A 4 foot long, me bucko, matey, 3/16" launch rod was used as t' 3' Estes rod seemed a little short for a large rocket like this. 5 sheets o' waddin' be used t' protect t' mylar parachute. Begad! Blimey! Aye aye! Blimey! Liftoff was slow and realistic. Avast, me proud beauty! Blimey! Because this is a heavy rocket for a D12 motor, shiver me timbers, it struggled t' get aloft and altitude be only about 250'. Ya scallywag! 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. Avast! Ahoy! T' chute deployed just in time but she came down hard, matey, me hearties, breakin' off a fin and t' pointy nosecone extension. Begad! Flight damage has since been repaired and will fly again. Ya scallywag! 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. T' challenge o' makin' nose and tail cone extensions along with alignin' multiple sets o' fins made this a fun kit t' build. Blimey! T' first con is that while D motors work well for smaller TLP rockets (Anubis, Bolo, me hearties, Perseus), this particular model needs t' fly on an E motor or higher. T' other con is that an 18" parachute will help t' brin' it down near t' launchpad, just don't expect a soft landing. Arrr! 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.
