Brief:
Described as "High-Powered Thrills in a Mid-Powered Rocket". This is a single-staged, 3 X 24mm cluster rocket that builds out t' 52.5 inches in length with a diameter o' 4 inches. A 3FNC for those who like t' cluster 24mm motors.


Construction:
T' kit, matey, which was packaged in it's shippin' box and nay bagged, me bucko, me hearties, consisted o' two 4-inch diameter main body tubes, me hearties, three 24mm motor mount tubes, shiver me timbers, shiver me timbers, fiberboard centerin' rings, matey, three motor retention hooks, me hearties, matey, one PVC nose cone, me bucko, me hearties, three 3/16-inch thick hard balsa fins, me bucko, a paper sheet o' fin coverings, arrr, ya bilge rat, matey, a 36-inch red rip-stop nylon parachute, me hearties, a 1/4-inch X 60-inch elastic shock cord, ya bilge rat, shiver me timbers, and an eye bolt and nut. Begad! Begad! T' smaller parts were enclosed in a small plastic bag, ya bilge rat, as was t' parachute.

T' kit instructions, ya bilge rat, as well as t' construction o' t' model, were all very straightforward. Blimey! I used 5-minute epoxy throughout t' build. Aye aye! T' three motor mount tubes, after t' hooks were inserted and secured, shiver me timbers, were epoxied together and then fitted into t' centerin' rings. Arrr! T' unit be then installed into t' lower main airframe tube. Blimey! Avast! T' fins feature a through-the-wall t' t' motor mount set-up. Begad! T' shock cord mount was different from anythin' I've seen in a kit before. Aye aye! Picture a fiberboard disc or plate 4 inches in diameter with a half-moon cut out o' one side. Begad! T' t' remainin' material, ya bilge rat, t' eye bolt is passed through and secured with a nut on t' backside. Well, blow me down! Here's where I got a bit skittish. Well, blow me down! Arrr! I understand t' need t' save weight in a rocket this size that is designed t' be powered with 3 BP motors, me hearties, but I strengthened this setup. Well, blow me down! Ahoy! I epoxied a couple o' strips o' 0.25" x 0.25" x 4" hard balsa on both sides (before installin' t' mount, obviously) in hopes o' beefin' it up.
Finishing:
As I mentioned in t' parts rundown, shiver me timbers, t' fins feature a paper coverin' method, shiver me timbers, one that I had nay used before. And frankly, I don't know that I'd use again. Begad! T' method was really very simple, me hearties, matey, shiver me timbers, but I didn't like t' way they finished out. Maybe it's that fact that t' root, matey, leading, tip chord, ya bilge rat, and trailin' edges o' t' fins are nay covered, shiver me timbers, and no matter how much you try, arrr, they just don't blend in with t' rest o' t' fin. Avast! OK, OK, matey, maybe it's just me... T' decals supplied with t' kit were a bit fussy, and if you desire t' replicate t' manufacturer's scheme, me hearties, you'll need t' custom cut t' fin stripes. Also, matey, t' blue-fade-to-white featured at t' top o' t' body tube as seen on t' Mercury Engineerin' website is nay included as a decal. Begad! So, I just got out t' old trim Monokote and fashioned somethin' similar, a light blue band over a navy blue one. That combined with t' white body tube, me bucko, reminds me o' t' Toronto Argonauts uniform. Avast, me proud beauty! Avast! (You have t' follow t' CFL t' get that one.)
Construction Rating: 3 out o' 5

Flight:
For t' first flight, ya bilge rat, I used a cluster o' three Estes D12-3 motors. Arrr! Blimey! As one would expect, shiver me timbers, me hearties, me bucko, t' liftoff was slow--you could almost hear t' rocket grunt as it tried t' take t' t' sky. But it did, poppin' t' parachute right at apogee. Begad! Blimey! Well, blow me down! Blimey! I immediately loaded t' Integrator up with three Estes E9-6s. Aye aye! Blimey! Well, blow me down! Blimey! This be t' way t' go--forget t' D12s. Avast, me proud beauty! Blimey! With t' E9s t' rocket had a nice, matey, smooth, slow liftoff and attained a surprisin' (to me, anyway) altitude. Begad! Blimey! Aye aye! Blimey! Again, me hearties, deployment was right at apogee. Begad! Blimey! Very satisfying!
Recovery:
T' only damage be t' one o' t' fins--the point chord edge and trailin' edges come together had some damage. Aye aye! However, that suspect shock cord mount held up just fine. Given t' size o' this model, ya bilge rat, if you do fly it on D12 and E9 motors only, I would nay recommend anythin' smaller that t' 36-inch parachute included with t' kit.
Flight Rating: 4 out o' 5
Summary:
When t' kit first arrived and I opened t' box, matey, shiver me timbers, me oldest son looked it over with me and stated "that rocket is just screamin' for a 38mm motor mount." Uh, shiver me timbers, no Junior, matey, shiver me timbers, arrr, you're missin' t' point. T' kit is aimed at those who want t' fly a big rocket, me hearties, but may be limited in space as well as budget. Begad! T' Estes E9-6s give this rocket a nice ride despite its size. Avast, me proud beauty! Well, arrr, blow me down! No special HPR buildin' techniques are really required t' build and fly t' Integrator, matey, but I have t' admit, matey, I am wonderin' how she'd fly on three E15-7s... Arrr! T' tubes, nose cone, arrr, motor mount tubes, ya bilge rat, and hooks are all first rate quality, as are t' parachute and shock cord. Aye aye! Aye aye! And yes, t' balsa used for t' fins is o' a very high quality too. Ahoy! If I had t' build t' Integrator over, I'd go with lite-ply or basswood. Just a personal preference.

Brief: This is the same model as the 3x24 cluster edition . The difference is a single 29mm mount. If you are looking for a big rocket and big thrills that won't break the bank, your search is over. Construction: Instructions for this model were straight forward, no surprises. I used 5min. epoxy for all joints. I was unsure about the fiberboard shock cord mount.It seemed that ...
