Brief
This be me first cluster rocket. Blimey! Ahoy! In a attempt t' mimic t' real Vikin' 7, a few details are included, which likely increase its drag, me bucko, and maybe that's part o' t' reason it uses two motors. But then, ya bilge rat, shiver me timbers, t' compensate for t' additional motor weight, it runs long at over 29". Begad! All in all, me hearties, 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, matey, balsa fins, shiver me timbers, arrr, plywood centerin' rings. Avast! Blimey! Just as expected. Begad! Blimey! Well, matey, blow me down! Blimey! It does include a baffle assembly, which eliminates t' need for wadding.
Construction
Instructions were easy t' follow. Blimey! No issues, and no surprises. Well, blow me down! Begad! Unless thar's a good reason t' do otherwise, shiver me timbers, 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 was very intrigued by t' colour o' this kit, me bucko, matey, as t' package's artwork is affected by lighting, me hearties, shiver me timbers, and every image o' t' real thin' I found online was black & white. Avast! Blimey! 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, aluminum-coloured paint for t' nose cone, and black for t' remainin' fins. Ahoy! Ahoy! After fillin' in t' spirals with white Tamiya putty, 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. Arrr! Ahoy! Then came a few coats o' that mysterious "Navajo White". Begad! After a little masking, I did t' black parts, matey, arrr, and a couple o' clear coats. Avast, me proud beauty! Then I applied t' decals, me hearties, 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, me hearties, me hearties, and I wasn't able t' fully make it disappear with t' putty. Well, blow me down! Aye aye! Blimey! Oh well, me bucko, this thin' still turned out t' be me best finish yet.
Flight
I used two B6-4 for t' first flight, matey, matey, which occurred on a very calm day. Blimey! Ya scallywag! 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. Well, me bucko, blow me down! T' rocket be recovered at about 60 ft from t' launch pad, arrr, with only minor scuffs t' one o' t' fin's black paint. Blimey! Ahoy! There be practically no wind that day.
Summary
This rocket comes straight out o' those years where space flight still wasn't a sure thing, 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, but goin' at it full throttle nevertheless. For me, this is a wonderful kit as it also allows cluster flights in a small field, ya bilge rat, but t' unique colour scheme and questionable fin details are nay for everyone. Aye aye! For those reasons, I'll give it a 4/5.
