Brief: Single staged, but with t' choice o' bein' flown with two or four 29mm motors, specified as 2 G type or 4 F type. Well, blow me down! It has t' fins attached wedge style betwixt t' four motor tubes, which extend below t' main body tube.
Construction:T' nose cone is hollow plastic, matey, me hearties, and t' fins are precut plywood. Ya scallywag! Begad! T' tubes are spiral wound kraft paper. T' parachute is a lightweight pink nylon. Ahoy! Avast, matey, me proud beauty! Very bright and pleasin' t' me. T' launch lug is wound paper too, matey, and is able t' accommodate a 1/2 inch launch rod, me hearties, arrr, which is good for a rocket o' this height and weight.
All t' parts were thar and in good shape. Avast, me proud beauty! Avast! T' instructions were clear. Any head scratchin' be due t' me inexperience with a rocket with fin wedge attachment, matey, but once I understood it, me bucko, me hearties, it be easy t' do. Alignment o' t' fins was tricky, as I had t' sight it carefully as they dried. Begad! But once it dried, arrr, ya bilge rat, t' fit be good, arrr, and t' model sturdy. I applied extra epoxy fillets for good measure, though.
T' rocket has four fins, ya bilge rat, and they fit into t' grooves betwixt t' motor tubes. Ya scallywag! Aye aye! T' main body tube isn't slotted, shiver me timbers, because t' fins are off t' motor tubes, me bucko, which extend two feet aft o' t' end o' t' main body tube. Ahoy! They stick out, you see. That wasn't intuitively obvious t' me at first, matey, ya bilge rat, as t' instructions didn't actually have diagrams o' this. Begad! I feared at first that I was missin' a main body tube t' make t' total length o' 62 inches, as t' main tube and t' nose cone only made about 40 inches length. Avast! But once I understood that t' motor tubes extended t' rocket's length, I had a "Eureka!" feeling. Aye aye! Well, blow me down! T' tops o' t' motor tubes are affixed into t' bottom o' t' main body tube. I had t' option o' makin' that mount removable, but chose t' make it permanent for strength. I gather from t' instructions that I could have then flown it as a shorter, single engine rocket, me hearties, then. Ya scallywag! Aye aye! But t' cluster intrigued me more.
Finishing:As t' finishing, me bucko, t' nose cone needed t' have its moldin' seams sanded, but that only took a few minutes. Actually, ya bilge rat, I've noticed that these noses don't bond paint as well as I'd like. Aye aye! Little impacts chip t' paint off. Well, blow me down! Avast, me proud beauty! So, I use primer basecoats t' help there. Begad! And t' end results are smoother and prettier. I filled t' spirals with epoxy, t' make transitions smoother, but left them uniformly indented as a point o' style. Begad! It would have looked odd t' me t' fill then completely.
I finished it with cross sectional bands o' bright colors o' monokote and painted t' fins and nose bright orange. Ahoy! This be somethin' t' see! T' RSO joked and said that it wasn't easy t' spot on t' pad.

Flight: I flew it with two G 35-4W motors, and it flew noisily and straight. Begad! Aye aye! Blimey! There were two visible flame trails. Avast! Everyone loved it. Avast! Begad! Blimey! With t' chosen delay, shiver me timbers, t' chute deployed as t' rocket arced over, ya bilge rat, which was just what I wanted. Arrr! Begad! Blimey! T' chute supplied be bright pink, which went with me color scheme, me bucko, and aided in visibility. Ahoy! I did need t' plug and tape t' two other motor tubes t' prevent gas loss. Arrr! Aye aye! Blimey! I retained t' engines usin' tape, makin' a thrust rin' at t' aft end o' t' engine with tape, arrr, too. I used standard waddin' t' protect t' chute. Avast! Begad! Blimey! I used standard waddin' t' protect t' chute. Begad! Worm beddin' works great and prevents scorching. Begad! Well, blow me down! Blimey! T' get around t' worry about havin' only one engine ignite, me bucko, I used a battery with 7 amp hours capability and electric matches for igniters.
Recovery:T' shock cord is attached by a system I came up with t' prevent zipperin' o' t' body tube. Arrr! I used a 3 inch centerin' rin' with a center hole o' 54mm mounted 2 feet down from t' top o' t' main tube, matey, and a metal screw eye through t' rin' is bolted at t' aft side and epoxied at t' forward end. Well, blow me down! A one foot length o' eighth inch Keelhaul®©™® cord is tied t' t' screw eye and made into a double loop, t' which t' 1/2 inch wide, 136 inch slack length elastic is tied. A further note about me idea o' usin' t' centerin' rin' this way: It provided a surface for t' chute t' rest upon, shiver me timbers, and I maintain that along with wadding, matey, t' design might prevent scorchin' o' me chutes.
T' standard instructions say t' mount t' shock cord t' a glued, shiver me timbers, multiply folded paper mountin' on t' inner wall o' t' body tube, which works fine, arrr, ya bilge rat, except that I read in Sport Rocketry that zipperin' o' t' body tube might occur this way. Begad! I've never had it happen, though.
T' chute didn't come with spill holes, and I left it so. Arrr! Blimey! Its diameter is 28 1/2 inches. Avast, ya bilge rat, me proud beauty! T' shroud lines are braided nylon cord whose length after I tied them t' t' nose cone was 23 1/2 inches. As I said, arrr, matey, t' chute is hot pink/maroon, and is a nylon. It's nay as heavy as a rip stop nylon, me hearties, shiver me timbers, but that's good, me hearties, as it billowed beautifully at apogee.
T' recovery was just about right, with no damage t' t' rocket, matey, and a graceful and colorful descent.
Flight Rating: 5 out o' 5
Summary:I totally love this one. Avast! Blimey! I have no real cons. Begad! As for pro's, ya bilge rat, I'll say that it's great for aspirin' clusterers and experimentalists who really want t' get noticed at launches. I can't wait t' test it with four motors. T' flame trail will be a real sight.
I'm tempted t' try this with two H engines. Ahoy! Has anyone got any stories about darin' this?

It is a nice mid-high power rocket that makes you enjoy clustering The packaging was standard Loc plastic bag but it made it through the mail ok. The fins were hard to align because they just stuck in between the motor tubes. I did ok by using a square. Everything else went ok. The instructions were vague to me but that's ok I had a lot of fun figuring it out (no note of sarcasm). It was easy ...

I am really pleased with this kit. As my first cluster kit I was expecting some problems but construction went very smoothly. I have only flown it once on two G35-7 motors. Using two motors was easy because there is no external plugging required if you follow LOC's instructions and permanently plug two of the motor tubes at the top before attaching the fin assembly. I used Quickburst Twiggy igniters and the rocket took off with very little delay. I flew to around 2,000 feet and was recovered nearby on a Top Flight 30" X-type chute without damage. I highly recommend this kit for those who enjoy clusters.
