Brief:
T' LOC/Precision Iris is a 3" diameter single stage rocket. Begad! It can be built as 1/4 size sport scale Iris rocket. Ya scallywag! Aye aye! Recovery is via a 36" parachute. Blimey! I modified it t' use electronics for dual deployment.

Modifications:
I built everythin' stock except for t' deployment/recovery method. Ya scallywag! I converted t' coupler t' an electronics bay. Begad! Ahoy! I built this by addin' another bulk plate assembly and a coupler tube stiffener, matey, shiver me timbers, also purchased from LOC. Avast, shiver me timbers, me proud beauty! I cut t' stiffener down so that each end be recessed 1/4" from t' edge. Blimey! Avast! This allowed room for t' bulk plates t' fit in. Begad! Avast! I drilled two matchin' holes in each bulk plate for #10-20 threaded rod t' go through. Arrr! I put win' nuts on t' ends o' t' threaded rod t' pull t' bulk plates tight against t' stiffener tube. Aye aye! T' electronics sled had a 1/4" tube glued t' it that slid onto one o' t' pieces o' threaded rod. Aye aye! (I should have made it go over both pieces though.) I cut a 3/4" piece o' body tube and glued it in t' middle o' t' coupler. Aye aye! This allowed me t' permanently mount t' armin' switch, which from Newton's 3rd Rocketry. Avast, me proud beauty! It be also a good place for t' static port hole. Aye aye! This e-bay design, usin' t' included coupler had plenty o' room for me Perfectflite HiAlt45K.

I used some tubular nylon that I already had for both sections. Well, blow me down! Arrr! T' lower half attached t' a 1/4" eye-bolt screwed into t' motor's forward closure.

Construction:
T' box contained 2 sections o' 3" diameter body tube. Aye aye! Arrr! One o' them be pre-slotted. There were two 1/8" 5-ply centerin' rings, and four 1/8" 5-ply fins. T' rest o' t' parts included a 38mm motor mount tube, elastic shock cord, 36" parachute, plastic nose cone, ya bilge rat, 3" tube coupler, and a bulk plate assembly.

Finishing:
I didn't put much effort into finishing. Arrr! T' decals that came with it appeared t' be homemade and sprayed with clear coat. I decided nay t' use them and originally planned t' paint it close t' one o' t' paint schemes o' t' real Iris. Avast, me proud beauty! I didn't do any finishin' work on t' tubes or fins other than a little sanding. I applied two coats o' white primer and two coats o' white gloss paint. This was all I could get done before t' launch. Ahoy! Ahoy! I had planned t' do more later.

Flight:
Both flights were fast and straight. Avast, me proud beauty! Aye aye! Each flight be was powered by a J motor usin' DPS SRB propellant. Begad! Ahoy! T' first flight reached an altitude o' 4212 feet. T' rocket was destroyed on t' second flight.

Recovery:
Recovery for t' first flight was perfect. At apogee t' first charge fired, shiver me timbers, separatin' t' two main sections which were tethered by 25 feet o' tubular nylon. T' second charge ejected t' parachute at 400 feet.

T' second flight suffered a failure o' some sort in t' electronics. Aye aye! Blimey! I think it be more me failure in how I mounted t' electronics and nay t' manufacturer. Ya scallywag! Avast! Blimey! Neither charge fired, and I suspect thar was a power disconnect. Begad! Avast! Blimey! I was careless in how I mounted t' battery and think it might have come loose or jarred t' altimeter. Aye aye! Blimey! I also should have mounted t' sled over both pieces o' threaded rod t' keep it from rotating. I had added some foam underneath t' sled but don't think it helped much. Avast, me proud beauty! Almost everythin' was destroyed when it hit t' ground. T' parachute, motor hardware and fins were OK. T' rest o' t' rocket be unrepairable as well as t' altimeter and Beeline transmitter.

Summary:
PROs: I think t' LOC/Precision Isis is a great rocket. I would like t' build another one some day. T' parts were extremely good quality. T' instructions were easy t' follow. It flew great. Well, arrr, blow me down! Also, because o' t' dimensions, shiver me timbers, I had t' option t' make a sport-scale Iris.

CONs: T' only issue I found be t' pre-made slots did nay appear t' be perfectly spaced from one another. Avast! Ya scallywag! I be able t' work around this.
