Brief

This be me first cluster rocket. In a attempt t' mimic t' real Vikin' 7, me bucko, a few details are included, shiver me timbers, me bucko, matey, which likely increase its drag, and maybe that's part o' t' reason it uses two motors. But then, ya bilge rat, me hearties, matey, t' compensate for t' additional motor weight, shiver me timbers, it runs long at over 29". Begad! All in all, it makes for a surprisingly beautiful kit with a very unusual colour scheme.

Components

Materials are very standard for an intermediate level kit: polypropylene nose cone, ya bilge rat, ya bilge rat, balsa fins, plywood centerin' rings. Arrr! Just as expected. Aye aye! It does include a baffle assembly, me hearties, which eliminates t' need for wadding.

Construction

Instructions were easy t' follow. Avast, me proud beauty! No issues, me bucko, and no surprises. Well, matey, blow me down! Unless thar's a good reason t' do otherwise, ya bilge rat, I use CA glue when I need an immediate bond, wood glue when I need time t' do precise adjustments, and epoxy when I need maximum strength.

Finishing

I was very intrigued by t' colour o' this kit, arrr, as t' package's artwork is affected by lighting, shiver me timbers, and every image o' t' real thin' I found online be black & white. Begad! Was it light brown? Light grey? Fortunately, t' instructions specified t' use o' Rust-Oleum's "Navajo White" for t' body and some o' t' fins, me bucko, aluminum-coloured paint for t' nose cone, and black for t' remainin' fins. Aye aye! After fillin' in t' spirals with white Tamiya putty, shiver me timbers, and sandin' everything, me hearties, arrr, ya bilge rat, I ran a dowel through t' assembled rocket and laid it down like a shish kabob for a series o' about 10 light coatings o'  Rust-Oleum flat white primer coatings over 2 days. Then came a few coats o' that mysterious "Navajo White". Well, blow me down! After a little masking, I did t' black parts, and a couple o' clear coats. Then I applied t' decals, arrr, me bucko, and finished off with a few more clear coats.

T' only issue I had with t' finishin' is that since t' body is actually made out o' two body tubes joined by a coupler (the baffle), thar be a deep slit where they meet, and I wasn't able t' fully make it disappear with t' putty. Arrr! Blimey! Oh well, arrr, shiver me timbers, this thin' still turned out t' be me best finish yet.

Construction Score: 5

Flight

I used two B6-4 for t' first flight, which occurred on a very calm day. Avast! T' flight trajectory had a very shallow s-turn at first, and ended up goin' straight up.

Recovery

I upgraded t' parachute t' 15" nylon before t' first flight. Ya scallywag! T' rocket was recovered at about 60 ft from t' launch pad, with only minor scuffs t' one o' t' fin's black paint. Aye aye! There was practically no wind that day.

Flight Rating: 5

Summary

This rocket comes straight out o' those years where space flight still wasn't a sure thing, ya bilge rat, and that's what I like about it. Avast, me proud beauty! It represents t' excitement o' those early days o' R&D and that feelin' o' nay quite knowin' if a project will succeed or not, matey, but goin' at it full throttle nevertheless. Aye aye! For me, ya bilge rat, me hearties, this is a wonderful kit as it also allows cluster flights in a small field, but t' unique colour scheme and questionable fin details are nay for everyone. For those reasons, me bucko, shiver me timbers, shiver me timbers, I'll give it a 4/5.
