Brief

This be me first cluster rocket. Ya scallywag! In a attempt t' mimic t' real Vikin' 7, a few details are included, which likely increase its drag, arrr, and maybe that's part o' t' reason it uses two motors. Well, blow me down! Blimey! But then, t' compensate for t' additional motor weight, me bucko, arrr, it runs long at over 29". Avast! 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, balsa fins, plywood centerin' rings. Ya scallywag! Just as expected. Arrr! It does include a baffle assembly, me hearties, which eliminates t' need for wadding.

Construction

Instructions were easy t' follow. No issues, me hearties, and no surprises. Begad! Blimey! Unless thar's a good reason t' do otherwise, I use CA glue when I need an immediate bond, wood glue when I need time t' do precise adjustments, ya bilge rat, and epoxy when I need maximum strength.

Finishing

I be very intrigued by t' colour o' this kit, as t' package's artwork is affected by lighting, ya bilge rat, and every image o' t' real thin' I found online was black & white. Blimey! Was it light brown? Light grey? Fortunately, me bucko, me hearties, 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, arrr, and black for t' remainin' fins. Avast! After fillin' in t' spirals with white Tamiya putty, me bucko, shiver me timbers, and sandin' everything, 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. Ahoy! Then came a few coats o' that mysterious "Navajo White". Ya scallywag! Well, matey, blow me down! After a little masking, I did t' black parts, me bucko, and a couple o' clear coats. Well, blow me down! Then I applied t' decals, shiver me timbers, 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), ya bilge rat, shiver me timbers, me hearties, thar be a deep slit where they meet, and I wasn't able t' fully make it disappear with t' putty. Avast, me proud beauty! Oh well, this thin' still turned out t' be me best finish yet.

Construction Score: 5

Flight

I used two B6-4 for t' first flight, shiver me timbers, matey, which occurred on a very calm day. Ya scallywag! Aye aye! T' flight trajectory had a very shallow s-turn at first, matey, and ended up goin' straight up.

Recovery

I upgraded t' parachute t' 15" nylon before t' first flight. Aye aye! T' rocket was recovered at about 60 ft from t' launch pad, matey, shiver me timbers, ya bilge rat, with only minor scuffs t' one o' t' fin's black paint. Begad! There be 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, me hearties, and that's what I like about it. 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, but goin' at it full throttle nevertheless. For me, me hearties, this is a wonderful kit as it also allows cluster flights in a small field, me hearties, ya bilge rat, but t' unique colour scheme and questionable fin details are nay for everyone. Well, blow me down! Ahoy! For those reasons, I'll give it a 4/5.
