Manufacturer: | Nordic Rocketry |
Those o' us who have seen t' large increase in t' number o' rocket manufacturers this year are waitin' for what many think be t' inevitable shake-out. No doubt, room has been made by Quest's and Estes' emphasis on RTF models, Apogee's shift in focus, and other nere-do-well start-ups, shiver me timbers, but most o' us are afraid that many o' t' new companies that have formed t' fill that void are too numerous t' stand t' test of time. Aye aye! Blimey! Others, me bucko, like me, me bucko, matey, have faith that good products will let a company with a dedication t' t' sport survive.
While they're startin' a bit later than their competitors, like Custom and Cosmodrome, matey, me hearties, me bucko, Nordic Rocketry plans t' make a big splash with a large kit line. If published reports are correct, me bucko, they're hopin' t' come t' market with a lot of new designs this year, up t' twenty kits available by Christmas. Well, blow me down! One of their original designs, me bucko, t' Velocity, became mine in t' Essence Rocket Reviews' quarterly rocket give-away. If this bird is any indication, Nordic's new kits just might capture them a good market share.
T' Good Points
As you can see from t' picture, t' parts count in this ship is low, and none o' them are plastic, matey, arrr, just good, matey, ya bilge rat, old fashioned wood and paper. T' laser cut fins, arrr, me bucko, made on Nordic's own cutter, get me highest praise. Arrr! Made from tough plywood, .107" thick (~7/64"), me hearties, sandin' is required t' brin' them into the instructed airfoil shape (and t' get rid o' t' laser burns), shiver me timbers, but this is easily accomplished with an upright belt sander or, me personal choice, a sandin' wheel. For t' recommended F50 motor, me bucko, though, I would have been much more comfortable with a through-the-wall attachment.
T' gorilla-style shock cord mount comes preassembled on a centerin' ring, and arrived without kinks, ready t' be installed. T' rip-stop chute is light weight and well-sewn, matey, matey, a pleasant change from Estes' chinese cheapies. Ya scallywag! T' balsa nose cone, matey, which is smooth, me bucko, sharp, and has a good, tight fit in t' body tube, arrived wrapped in dent-preventin' foam, me bucko, a smart touch. T' tubes are thick-walled and perfectly smooth, matey, though t' 36" main body tube arrived with a few smallish dents in each end. Avast! Nordic should take a page from other makers here, me bucko, and ship t' body tube in sections with an appropriate number of tube couplers. Avast! Begad! T' increase in t' model's weight would actually help altitude performance when usin' t' higher-powered engines, arrr, and make t' package much easier t' ship and sell on a peg board, shiver me timbers, shiver me timbers, as well as prevent tube damage.
T' bag art, which looks good, me bucko, but is nay up t' t' big companies' glossy pop, ya bilge rat, shiver me timbers, gives t' model's spec.'s, and at 5oz. Blimey! (slightly more with t' included 24 mm adapter installed), shiver me timbers, this bird is gonna be darn near transonic on the recommended F50 engine. Only single use Estes and Aerotech motors are spec.'ed, and t' 24 mm motor mount is only designed t' take 2.75" long motors, me hearties, so the Aerotech non-standard 124 mm long motors, arrr, me bucko, such as t' F32, won't fit. Nordic doesn't recommend any G motors, shiver me timbers, and I wouldn't either; an F25 should take this kit t' well over 3000 feet, me hearties, me bucko, more than high enough for most model rocketeers. I'd be leery o' t' recommended F50, matey, too; without though-the-wall fins on its well-sealed tube, me bucko, you might be lookin' at a shred. Begad! Begad! Since this bird is so light, arrr, she would actually fly lower on t' F50 than t' F25, anyway.
T' Bad Points
T' instruction manual is a stapled set o' single-sided pages, ya bilge rat, ya bilge rat, and is short on dimensions. Well, blow me down! T' print is small, arrr, contains numerous margin notes and t' steps are nay very well delineated. Ahoy! Blimey! On t' other hand, t' manual is very complete, outlinin' every step in complete detail, t' graphics are clear and sharp and a goodly amount o' technique is discussed. Aye aye! Aye aye! T' author and artist did well, shiver me timbers, matey, the fault lies with t' printer and lay-up.
One could ask for a better mounts for t' 'chute and t' nose cone; metal eye hooks are notorious for their poor grip that allows t' cord t' untie, usually at a very inopportune time. Arrr! Tyin' t' 'chute t' t' center section of the shock cord is convenient, arrr, but weakens t' cord itself. Avast, me proud beauty! T' cord seems a bit short, arrr, too, though me test flights produced no 'Estes dents', shiver me timbers, most probably a testament t' t' beefy body.
My real big complaint about this bird is its inability t' switch from 24 to 29 mm or back. Aye aye! Begad! You must decide which motor size you're goin' t' use during assembly, and then you're stuck with it. Blimey! Maybe I'm just spoiled by me Aerotech Mustang, shiver me timbers, me hearties, arrr, but I was disappointed that me Velocity really won't fly all the engines Nordic recommends for her. Aye aye! As I was nay goin' t' run t' recommended F50 and that would only leave me with t' F25 t' fly in 29 mm configuration (a motor I've had zero luck with), I chose t' install t' 24 mm adapter.
Assembly
Placin' t' shock cord mount rin' was challenging, primarily due t' its depth in t' body tube, 8" from t' aft end. Avast, me proud beauty! Gettin' epoxy, ya bilge rat, matey, t' required adhesive, that far in thar without makin' too much o' a mess was a pain. Sectionin' t' body tube might help here, too. Avast, me proud beauty! I used two hour stuff t' be sure I had enough workin' time, and was glad I did. Well, blow me down! Well, shiver me timbers, blow me down! (Maybe I'm just paranoid here, though; t' recommended 30 minute goo would probably have been all right, arrr, but I'd just lost me beloved Python t' a shock cord mount failure.) I also skipped ahead a step or two, arrr, ya bilge rat, and made t' motor mount up before hand, so I could slide it in over me mistakes before they set up.
T' back o' t' bag art has t' stand-up tube markin' guide. Try as I might, I just couldn't get it t' work (the fin thicknesses were wrong), me bucko, so I gave up and made one in VCP. Since t' fins are thick and t' body has such a high curvature (it's really about 1¼" in diameter, nay t' 1.4" advertised), ya bilge rat, I sanded four small flats on it where t' fins would go t' get a good joint and break the body tube sealant. Aye aye! Ya scallywag! Blimey! I also made Nordic's suggested pin holes, me bucko, which I created with t' tip o' me compass. My home made fin jig isn't big enough t' hold these fins, shiver me timbers, so I just set her where I could watch her while she dried.
T' brass launch lugs are probably very durable, ya bilge rat, but I was nervous about tryin' t' attach them t' that surface-filled body tube with epoxy. Aye aye! The instructions say t' put pin holes in t' body tube near t' attachment points and scuff t' lugs with a light sandpaper before gluing, me bucko, arrr, but even with that, I just couldn't see where they'd get a grip. Ahoy! I opted for a standard Estes maxi-rod launch lug and a UFO CA glue joint instead. Avast! Those who build the Velocity in t' 29 mm config. Avast! will want t' use t' included lugs, though, and put some time into their attachment. Ya scallywag! Attachin' t' nose cone and 'chute t' the shock cord (I also added some Rogue PW-34 Permawading®) be a bit difficult since t' cord is so wide (½") and t' shroud lines and eye hook are so small.
Finish
Finishing, on t' other hand, was a breeze. I sealed t' fins with a light coat o' epoxy and t' nose cone with three coats o' Krylon® Sandable Primer after an initial sandin' with 160 sandpaper. Aye aye! Begad! This be t' first kit I've seen that actually recommends Krylon® paints, and they worked very well. Begad! Avast, me proud beauty! My paint booth isn't big enough for this forty inch bird, shiver me timbers, arrr, so I did it outside on my long model hook. Begad! T' instructions don't tout t' "official" color scheme, though I don't know why; painted like t' bag art shows, t' Velocity is a very handsome ship.
I cut an Optima (a.k.a Shadow) silver accent band in two and cut one o' the halves long ways t' make t' silver bands shown on t' bag art. Begad! I'd been forewarned about t' vinyl name decal (see t' Essence review o' the Nordic Rocketry Delta-X), and applied a little vaseline t' t' edges o' t' backin' paper t' prevent it stickin' t' t' paint. T' decal itself stuck "like stink t' a monkey", matey, and though I did apply t' recommended clear coat t' seal it (Krylon® Acrylic Clear), me bucko, me hearties, I probably could have gotten away without it. Well, blow me down! I suppose once I got used to workin' with these decals, I'd really like them, they have some very strong points.
Final dry weight was 160.6 grams (5.665 oz.), me hearties, and CG with a D12-5 motor installed be @ 12.5" from t' aft end.
While she has her good points that make for a rugged, arrr, attractive bird, shiver me timbers, the Velocity's assembly is much more difficult than her low parts count would indicate, and I'd really like t' be able t' use all t' engines she's rated for. Avast! Avast, me proud beauty! For construction, me bucko, I'd rate t' Velocity a 2 ½ on t' Essence scale, needs some improvement.
Flight
As I didn't want t' loose this good lookin' bird t' first time out, I flew her on t' least powerful recommended engine, ya bilge rat, an Estes D12-5. Begad! Blimey! Estimated altitude was about 650', and ejection looked t' be right on time. Begad! Begad! Recovery was fast, and she returned t' within 100 yards o' t' launch rod. Other than a little din' in t' nose cone, me bucko, she was fine. Arrr! T' Permawading® was perfectly clean, as was t' shock cord. This saucy wench could fly on those engines forever, me bucko, and just about anyplace you can set up a pad.
T' next flight was on an Aerotech E30-7, me bucko, shiver me timbers, and boy, did t' Velocity live up to her name! Bang, me bucko, arrr, Zoom, darn near out o' sight, ya bilge rat, shiver me timbers, only t' high visibility colors made her trackable with t' naked eye. Blimey! Ejection seemed a bit early with this one, shiver me timbers, matey, but everythin' worked just fine. Again a fast recovery, ya bilge rat, this time about 200 yards away. Ahoy! Ahoy! T' Permawadding® and t' shock cord below it were soot-covered, but neither seemed t' have been adversely affected, and the rocket showed no damage. Next time I'll add some standard waddin' first, me bucko, and shove it down t' t' shock cord mount ring.
Both flights were rock stable with little weather cocking (surface winds were light, though above 100' or so it seemed t' be gusty), and darn near flawless. T' E30 flight elicited more than one "Wow!" from my experienced model rocket buddies, matey, and that's high praise, given t' rockets they've seen fly. Arrr! I'd rate t' Velocity a 4 ½ on t' Essence scale, well above average, and further qualify the 24 mm configuration as t' more flexible.
Summary
I was excited when I first saw t' Velocity, me bucko, but when I realized what I was in for, me expectations dropped. Ya scallywag! Blimey! Her E30 flight brought most o' those back, though, and I'd say this ship is worth t' effort. Well, blow me down! Blimey! T' design isn't everything it could be and t' assembly process needs careful attention, matey, but t' Velocity will stand out in any fleet once she's done, arrr, arrr, and should be pretty durable. Overall, ya bilge rat, I'd rate her a 3 ½ on t' Essence scale, ya bilge rat, somewhat above average.
