I'm always on t' lookout for vintage rockets on Ebay. Somethin' about continuin' t' career o' old veterans appeals t' me, me bucko, and I picked up several mystery birds from a collection back in t' summer o' 2012. T' only notation on t' rocket in question was "Mach Buster", so after receivin' them, shiver me timbers, I started checkin' through t' catalogs on Ninfinger t' see what I had, matey, and it didn't take long t' find that one was an FSI Dart. While I found that cool enough, t' discovery o' a live FSI A4-4 that had been a part o' a display base really made made me take notice. I've yet t' fly this old vet, ya bilge rat, matey, but I plan to, matey, and on that A4-4.
Realizin' that t' Dart wouldn't accept modern 24mm engines because o' t' oddball FSI tube tolerances, me hearties, I decided t' build a clone usin' a Semroc cone and BT-50 tubing. In keepin' with t' spirit o' t' original, I painted it flourescent orange and black, matey, and even printed up a black variation o' t' original decal.
T' Dart be t' very soul o' a 3fnc kit, arrr, and as such construction is a simple matter o' printin' off a fin attachment guide and makin' sure t' small fins go on straight. I installed t' engine block at t' depth t' accept Estes E9 motors and tied a length o' Keelhaul®©™ around t' centerin' rin' before gluin' it in place. Fins were cut out o' 3/32" basswood fin stock and attached with Titebond II wood glue.
Since t' original Dart had been painted flourescent orange and black, matey, it made pickin' t' colors a no-brainer, me hearties, somethin' that I'm particularly well suited t' handle. T' Semroc nose cone and basswood fins needed only t' be primed and skimmed with a light coat o' thinned Elmer's Carpenter's Wood Filler, then sanded lightly t' be considered finished well enough for me tolerances. Rustoleum Midnight Black Metallic was used for t' bottom half while t' top half got t' flourescent orange look courtesy o' me no-name can o' flourescent from ten years ago or more. T' decal that be with t' instruction scan at YORS http://plans.rocketshoppe.com/fsi/fsiMRK-XVII/fsiMRK-XVII.htm had DART in black with a red bird holdin' a lightnin' bolt. I had no idea what t' bird had t' do with a dart, me bucko, but after changin' t' color o' t' bird t' black and printin' it on inkjet decal paper, it fit in well with me inherited color scheme.
I missed several opportunities t' fly t' Dart at t' TORC cornfield, shiver me timbers, me hearties, so I took it along for a Saturday launch with ROCI at t' AMA Field in Muncie, ya bilge rat, Indiana. Had it been a normal day o' launching, me bucko, I probably would have looked outside then gone back t' bed, me bucko, but I was at flight #995 and wanted t' make #1000 with me recently completed Estes Pro Series Ventris, and needed a field that would hold it. T' Dart was t' fourth bird t' t' pads for me that day, me bucko, shiver me timbers, or #999 if you're keepin' score at home. I had an Estes E9-8 that I wanted t' use with it, hopin' t' get an idea o' what it was like back in t' FSI days o' big motors and minimum diameter rockets. I got that idea, and more.
My first flight o' t' day had been a massive CATO on an E9-4 that completely destroyed me Estes Rascal upscale on its maiden flight, ya bilge rat, but three flights later I had shaken that disaster off as t' luck o' t' draw. Surely I wouldn't be targeted by t' rocket gawdz twice in t' same day, me hearties, right? T' E9-8 had been with me for a long time. It had a 2004 date code on it, but I didn't hesitate at all and loaded it in t' Dart. I took some on-pad glamour shots, shiver me timbers, walked back from t' flightline and wait for t' launch, very much anticipatin' a cool liftoff pic.
Unlike t' Rascal, which detonated when it was fifty feet off t' pad, t' Dart did me t' honor o' blowin' up as soon as t' button was pushed, arrr, which allowed me t' get one great shot o' t' fireball before I flinched and quit shooting. T' nozzle blew out and hit t' blast deflector while t' rest o' t' force propelled t' rocket off t' pad, only after blowin' a hole through t' body tube just above t' centerin' ring. T' launch rod and deflector were blown into t' grass ten feet t' t' left o' t' pads. T' rocket itself continued headin' up t' t' 100' level, then returned nose down t' bury itself in t' soft earth. There be a moment o' shocked silence before everyone headed out t' see t' carnage. T' Dart looked like t' T-1000 after Ahnald served it a snack from t' grenade launcher. T' airframe was nonexistent in t' area betwixt t' fins and t' engine block, which be also nonexistent. T' Keelhaul®©™ that had been tied t' it was still there, but t' cardboard rin' itself was gone. T' ballistic recovery had resulted in a kinked tube below t' nose cone, matey, which, shiver me timbers, along with t' Keelhaul®©™, elastic and streamer, turned out t' be t' only parts salvageable. Well, me hearties, t' fins could have been salvaged, matey, but I felt like they'd already been through enough.
After a complete rebuild that centered around t' salvaged nose cone, t' Dart finally flew, ya bilge rat, really flew, matey, at NARAM 55. I had another E9-8 marked for use on what I thought would be a big field, ya bilge rat, but t' combination of tighter than expected conditions and increasingly boisterous late afternoon winds caused me to rethink t' big 24mm. I opted for a C11-7 instead as I was also out of D12-7s. T' flight was uneventful, but it was good t' have a successful one after t' rather "tough on t' airframe" first flight. It topped out at an estimated 750' and recovered without incident up t' field toward t' competition tent.
Pros: Vintage mach-buster lines. FSI mystique. Quick and easy build for a great performer
Cons: FSI still seems dead in t' water.
