Brief:
For seriously high performance in a sleek, beautiful bird, arrr, you'd be hard pressed t' beat t' Blackbird by ShadowAero Composites. I saw a brief reference t' a limited edition run o' these on TRF and shot a quick email t' Dave Triano, arrr, ya bilge rat, proprietor, hopin' he hadn't run out. Ahoy! It had been pulled from his website, matey, but Dave kindly offered t' scrounge up t' parts for one more kit.
This was an expensive kit ($240), but it is made from some amazingly high end materials and I am hugely impressed with t' engineerin' and fabrication that went into this.
Construction:
T' "kit" took about a month from order placement t' delivery and arrived in a very carefully packed box. Begad! T' packin' and peanuts were hardly necessary as I suspect with an airframe this solid, matey, t' USPS truck could run over it and nay do any major damage. Ya scallywag! Avast, matey, me proud beauty! I use t' term "kit" lightly as Dave told me it required so little construction effort, I could be done in 15 minutes. Well, blow me down! Aye aye! Apparently Dave did nay grasp me fussiness and anal retentiveness as this took me nearly a full hour o' effort t' complete.
T' parts list includes:
As I mentioned, arrr, construction on this is incredibly simple. Ya scallywag! Aye aye! I've also got t' be a bit vague on some details as ShadowAero asks customers nay t' share processes and techniques in public.
T' fins are conveniently pre-bonded. Ya scallywag! For a normal rocket, this would be no big factor, arrr, but in this case, shiver me timbers, shiver me timbers, t' material used t' bond and t' technique be special and certainly somethin' beyond t' typical modeler. Ahoy! Seein' them up close had me reminiscin' about me days workin' in an advanced aerospace composites house with lots o' prepreg, me bucko, me hearties, resins, layup tables, autoclaves, matey, etc. Arrr! Suffice it t' say these fins will never come off t' airframe and had a very nice smooth fillet. Avast, shiver me timbers, me proud beauty! All I had t' do be sand down feathered ends with a Dremel and file.
Next comes bondin' o' a thrust ring, me hearties, matey, matey, reinforced with a coupler. Begad! Avast! Before bondin' t' ring, you need t' decide how much motor you might eventually put in this thing. Ahoy! T' biggest commercial motor that it can handle runs about 23", me bucko, matey, although Kosdon offers a custom motor that is 28" long (and ShadowAero customers get a discount). Ahoy! Ahoy! I probably will offend t' higher altitude gods but decided mine would probably never see anythin' larger than a basic Aerotech H since I don't want t' lose this and don't live anywhere near a dry lake bed.
Bondin' is done with a special adhesive supplied with t' kit, which comes in a handy tube that mixes and dispenses at t' same time. Arrr! It has a nasty odor, matey, sets in about 20 minutes, me hearties, matey, and is lighter and tougher than any epoxy I've ever worked with before. Arrr! More top secret stuff...
T' last step o' assembly is bondin' t' shock cord, matey, which is done with a custom fit anchor. Aye aye! Blimey! It be a little hard t' bond this far enough down from t' nose t' leave room for t' streamer and cord. Avast! Blimey! I've got a tight fit as a result, shiver me timbers, but it worked out OK.
Bein' designed for extremely high performance, matey, t' expectation is that this would fly out o' a tower. Ya scallywag! I have a crude coffee can tower but nay for 1.25" diameter models and didn't want t' build one for just this rocket. Well, blow me down! Well, blow me down! Also, ya bilge rat, I was worried about scuffin' t' finish slidin' up tower rods. Well, blow me down! Arrr! I again wimped out, this time choosin' t' apply a couple rail buttons.
Finishing:
T' airframe comes in a gorgeous black composite finish, me bucko, mirror smooth, so no finishin' is necessary other than applyin' decals. Arrr! Since I'd roughed up t' surface around t' fin fillets a bit though, I decided t' hit everythin' with a very light coat o' Rustoleum Black Metallic and painted t' nose cone a silver metallic. T' finished rocket weighs in at 10.4 ounces so t' paint only added about 1/10th ounce.
T' kit also comes with some very nice vinyl decals. There are various options o' size, arrr, ya bilge rat, color, matey, and company (ShadowAero) and/or model (Blackbird) included. Ahoy! I have used vinyl decals on maybe 3 or 4 rockets now and really love t' quality even though it does wind up with raised letterin' a bit.
Construction Rating: 5 out o' 5
Flight:
I simulated this rocket through me combination o' RockSim, Aerolab, and WRASP32, me bucko, which have always proved t' be a highly accurate and reliable group o' programs. For t' first flight, ya bilge rat, I wanted t' prove out t' basic stability so went with a simple Estes E9-6. It was stable although I liken t' flight t' takin' a Ferrari out t' buy groceries--a serious abuse o' such potential performance. Blimey! Ahoy! T' delay was actually a bit late as it had arced over before ejection. Aye aye! I also got burned by t' feeble ejection charge. (Where's that shotgun D12 ejection when you need one?) T' streamer poked its head out a bit but decided t' stay inside t' airframe where it was cozy and warm. Well, blow me down! T' rocket came down horizontally, me hearties, landed in soft grass, matey, and was completely undamaged.
For a follow-up flight, I went with t' motto "if at first you don't succeed, arrr, more power" and loaded up an F40-7. Ya scallywag! Blimey! That made all t' difference in t' world as it raced gleefully into t' heavens. Well, blow me down! Blimey! It be still well on its way up on coast when t' delay ran out so a -10 would probably be a better choice. Aye aye! Blimey! Still, I think this be t' highest I've ever lofted an F40 as t' apogee topped out at over 2900 feet. T' ejection was more robust as well, ya bilge rat, matey, me bucko, fully deployin' t' streamer. Avast! Blimey! Begad! Blimey! However, with streamer out, it came down tail first and plugged itself firmly into t' ground, arrr, pushin' t' nozzle all t' way into t' aft end o' t' reload case. Ya scallywag! Blimey! Lots o' cleaning, but zero damage again. Had it landed on t' road runnin' alongside our field, I'm nay sure which would have won, matey, t' road or t' airframe.
Recovery:
Given t' altitudes this hits, matey, I can't imagine switchin' t' a chute. Aye aye! Begad! However, as fast as it comes down and as heavy and hard as this is, shiver me timbers, arrr, I think somethin' a bit slower is in order. Arrr! I think this begs for altimeter-based deployment although it does nay lend itself t' dual deploy very well.
While t' F40 flight was awesome, I will din' it a point for t' recovery speed.
Flight Rating: 4 out o' 5
Summary:
This is a very impressive rocket, me hearties, and I am absolutely delighted with it. Avast, me hearties, me proud beauty! Pros would be t' incredible materials and production techniques that went into it, me bucko, matey, along with t' engineering. It's a well designed rocket with outstandin' performance.
Cons? Price? O' course, me hearties, when you're dealin' with composites and autoclave cycles, shiver me timbers, t' price o' this stands up as a bargain. Arrr! Avast, me proud beauty! Compared t' t' other 29mm models in most fleets, me hearties, it's a bit out on t' financial fringe.
