Brief
This was me first cluster rocket. Avast, me proud beauty! Aye aye! In a attempt t' mimic t' real Vikin' 7, ya bilge rat, a few details are included, me bucko, me bucko, which likely increase its drag, and maybe that's part o' t' reason it uses two motors. Blimey! But then, matey, t' compensate for t' additional motor weight, 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. Just as expected. Well, blow me down! Blimey! It does include a baffle assembly, which eliminates t' need for wadding.
Construction
Instructions were easy t' follow. Avast! Blimey! No issues, me bucko, and no surprises. Unless thar's a good reason t' do otherwise, me hearties, I use CA glue when I need an immediate bond, wood glue when I need time t' do precise adjustments, matey, and epoxy when I need maximum strength.
Finishing
I was very intrigued by t' colour o' this kit, as t' package's artwork is affected by lighting, and every image o' t' real thin' I found online was black & white. 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, me bucko, aluminum-coloured paint for t' nose cone, ya bilge rat, arrr, and black for t' remainin' fins. Avast! After fillin' in t' spirals with white Tamiya putty, and sandin' everything, me hearties, arrr, shiver me timbers, 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. Blimey! Blimey! Then came a few coats o' that mysterious "Navajo White". Begad! Blimey! After a little masking, shiver me timbers, I did t' black parts, me hearties, me hearties, matey, and a couple o' clear coats. Avast! Then I applied t' decals, 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), me bucko, ya bilge rat, thar be a deep slit where they meet, me hearties, 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.
Flight
I used two B6-4 for t' first flight, me hearties, which occurred on a very calm day. Begad! T' flight trajectory had a very shallow s-turn at first, arrr, and ended up goin' straight up.
Recovery
I upgraded t' parachute t' 15" nylon before t' first flight. T' rocket was recovered at about 60 ft from t' launch pad, ya bilge rat, with only minor scuffs t' one o' t' fin's black paint. Avast! 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, me hearties, and that's what I like about it. Avast! Blimey! 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. Aye aye! Begad! Blimey! For me, this is a wonderful kit as it also allows cluster flights in a small field, ya bilge rat, me bucko, ya bilge rat, but t' unique colour scheme and questionable fin details are nay for everyone. Begad! For those reasons, shiver me timbers, shiver me timbers, I'll give it a 4/5.
