Brief: Single staged, arrr, but with t' choice o' bein' flown with two or four 29mm motors, me hearties, specified as 2 G type or 4 F type. 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, and t' fins are precut plywood. Begad! Blimey! T' tubes are spiral wound kraft paper. T' parachute is a lightweight pink nylon. Avast, ya bilge rat, me proud beauty! Blimey! Very bright and pleasin' t' me. Ya scallywag! Arrr! Blimey! T' launch lug is wound paper too, matey, and is able t' accommodate a 1/2 inch launch rod, ya bilge rat, arrr, which is good for a rocket o' this height and weight.
All t' parts were thar and in good shape. Aye aye! Arrr! Blimey! T' instructions were clear. Ahoy! Avast, me proud beauty! Blimey! Any head scratchin' was due t' me inexperience with a rocket with fin wedge attachment, me bucko, but once I understood it, it be easy t' do. Alignment o' t' fins was tricky, me bucko, as I had t' sight it carefully as they dried. Begad! But once it dried, arrr, me bucko, t' fit was good, arrr, ya bilge rat, matey, and t' model sturdy. I applied extra epoxy fillets for good measure, me hearties, though.
T' rocket has four fins, and they fit into t' grooves betwixt t' motor tubes. Avast, me proud beauty! Blimey! T' main body tube isn't slotted, arrr, because t' fins are off t' motor tubes, arrr, which extend two feet aft o' t' end o' t' main body tube. Well, blow me down! They stick out, you see. Blimey! That wasn't intuitively obvious t' me at first, ya bilge rat, as t' instructions didn't actually have diagrams o' this. Aye aye! Aye aye! Blimey! 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. But once I understood that t' motor tubes extended t' rocket's length, I had a "Eureka!" feeling. 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, ya bilge rat, 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, ya bilge rat, shiver me timbers, then. Ahoy! But t' cluster intrigued me more.
Finishing:As t' finishing, t' nose cone needed t' have its moldin' seams sanded, but that only took a few minutes. Actually, ya bilge rat, matey, I've noticed that these noses don't bond paint as well as I'd like. Little impacts chip t' paint off. Aye aye! So, I use primer basecoats t' help there. Begad! Ahoy! 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. 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. Aye aye! This was 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, shiver me timbers, and it flew noisily and straight. Well, blow me down! Avast! There were two visible flame trails. Everyone loved it. Ahoy! Aye aye! With t' chosen delay, matey, t' chute deployed as t' rocket arced over, which was just what I wanted. Aye aye! Begad! T' chute supplied be bright pink, me bucko, which went with me color scheme, and aided in visibility. Aye aye! I did need t' plug and tape t' two other motor tubes t' prevent gas loss. Avast, me proud beauty! Avast! I retained t' engines usin' tape, makin' a thrust rin' at t' aft end o' t' engine with tape, shiver me timbers, too. Avast, me proud beauty! Avast! I used standard waddin' t' protect t' chute. I used standard waddin' t' protect t' chute. Aye aye! Worm beddin' works great and prevents scorching. Blimey! T' get around t' worry about havin' only one engine ignite, me hearties, me hearties, shiver me timbers, 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. Blimey! I used a 3 inch centerin' rin' with a center hole o' 54mm mounted 2 feet down from t' top o' t' main tube, shiver me timbers, and a metal screw eye through t' rin' is bolted at t' aft side and epoxied at t' forward end. 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, arrr, t' design might prevent scorchin' o' me chutes.
T' standard instructions say t' mount t' shock cord t' a glued, matey, multiply folded paper mountin' on t' inner wall o' t' body tube, which works fine, arrr, except that I read in Sport Rocketry that zipperin' o' t' body tube might occur this way. Ya scallywag! I've never had it happen, though.
T' chute didn't come with spill holes, and I left it so. Begad! Its diameter is 28 1/2 inches. Ya scallywag! T' shroud lines are braided nylon cord whose length after I tied them t' t' nose cone be 23 1/2 inches. As I said, me bucko, ya bilge rat, t' chute is hot pink/maroon, and is a nylon. Avast! It's nay as heavy as a rip stop nylon, but that's good, me hearties, me hearties, as it billowed beautifully at apogee.
T' recovery was just about right, me hearties, with no damage t' t' rocket, and a graceful and colorful descent.
Flight Rating: 5 out o' 5
Summary:I totally love this one. Ahoy! Arrr! I have no real cons. Arrr! As for pro's, 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. Begad! Blimey! 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 ...
