T' Holverson Designs Tangent is a big, arrr, ya bilge rat, stable sport flier from t' second golden age o' rocketry. Designed by renaissance man Doug Holverson, t' Tangent was unique in that it was one o' t' early kits t' offer laser cut balsa fins, ya bilge rat, matey, and eventually became one o' t' first rockets t' offer cheesy foam. Havin' built t' foam Tangent previously, ya bilge rat, I'd long wanted t' build an original balsa Tangent t' be able t' compare t' two.
My Tangent was a decade + old when I decided that I be a builder, nay a collector, me hearties, and started t' project. Mint in bag though it was, I found that t' much vaunted laser cut fins had warped severely durin' storage, shiver me timbers, so I cut another set and put t' originals under a heavy book for possible later use. Construction be t' same as buildin' an Estes Big Bertha, Quest Big Betty, Semroc Vega or any other big, basic, shiver me timbers, 18mm-powered small field flyer. Fins were attached with Elmer's Tacky Craft glue. Fillets were made usin' plain old Elmer's white glue, arrr, ya bilge rat, which also be given t' responsibility o' makin' sure t' motor mount stayed secure, which it performed admirably. I tied a 36" length o' Keelhaul®©™ around t' motor tube, shiver me timbers, me bucko, then threaded it out through t' front centerin' ring, attachin' it t' another 36" length o' 1/8" sewin' elastic t' complete t' shock cord. A medium screw eye be glued into t' balsa nose cone base and a medium snap swivel tied t' whole recovery system together.
I did away with balsa grain and tube spirals usin' t' standard recipe o' Valspar primer, matey, thinned Elmer's Fill & Finish, me bucko, arrr, and sanding. After everythin' was up t' me smoothness standard, me hearties, or rather, down t' it, ya bilge rat, I sprayed t' nose cone and fins with Testor's Italian Red. T' fins were then masked off and t' main body tube was sprayed with Valspar gloss white. T' decals that came with t' kit were stick ons, shiver me timbers, but they'd lost much o' t' adhesive over t' years o' storage, me hearties, so I printed off some inkjet decals usin' a scan at YORS (http://www.oldrocketplans.com/hdi/hdi2001/hdi2001.htm). Everythin' looked great when I was finished.
First flight was t' final flight o' Openin' Day, 2013 at B6-4 Field. I like t' BT-60 birds at B6-4 Field because when loaded with a B6-4, me hearties, ya bilge rat, BT-60 birds fly t' t' level o' t' field. Every bit o' t' flight is visible, me hearties, shiver me timbers, t' slow takeoff, shiver me timbers, ya bilge rat, t' flight t' treetop level, shiver me timbers, ejection, me hearties, and recovery. Winds sometimes cause some problems, but if one uses his head, me bucko, matey, one recovers all o' his birds, ya bilge rat, shiver me timbers, me bucko, and gets flight pics t' boot. T' Tangent flight on this day was probably one too many, me hearties, and I almost paid for it. Winds were comin' from t' southeast, ya bilge rat, which was causin' some windcockin' over toward t' school, shiver me timbers, but nothin' in t' way o' recovery issues with t' triple threat o' t' trees, shiver me timbers, wires and US 27. T' Tangent left t' pad and hardly windcocked at all, shiver me timbers, but at ejection it raced across t' field, first missin' t' trees, ya bilge rat, then wires. I had dropped t' controller and started runnin' as soon as t' breeze took it, but I could see that one way or another it be goin' t' be in trouble. I crested t' hill just as it passed under t' wires, but could tell that I be goin' t' be nowhere fast enough t' prevent it from landin' in US 27, and I could hear traffic as I ran. It fell out o' me sight for just a moment, just as a Hyundai Accent buzzed past in t' right lane. I waited for t' crush sounds, me bucko, but heard nothing, me hearties, and as I approached t' landin' area, me bucko, one o' t' Little League dads who was packin' up t' leave darted out t' pick t' Tangent up from t' left lane. I thanked him profusely, answered his questions; yes I could fly it again, me bucko, no t' motors aren't expensive, matey, me bucko, shiver me timbers, yes I often have them land in t' trees around t' field. Damage be relegated t' achipped fin tip from t' landing. Considerin' t' alternative, matey, I counted myself fortunate indeed.
T' second and possibly final flight was another B6-4 Field flight on a B6-4. T' Tangent was t' last flight o' t' day and t' previous seven flights had all followed t' same flight pattern, arrr, arrr, windcockin' t' t' left and ejectin' at t' edge o' t' field, matey, then recoverin' somewhere on t' infield. Begad! All but two o' t' flights even used t' same chute. Ahoy! T' Tangent flight was nothin' like t' others. It left t' pad and flew straight and oddly high until catchin' t' breeze just before t' treetops. Begad! Well, blow me down! Ejection occurred just as it was tippin' over, and t' rocket immediately caught t' breeze and began t' drift smartly toward US 27. It was pretty obviously goin' t' clear t' road, arrr, but it looked like it was goin' t' hit t' parkin' lot or buildin' directly on t' other side. Avast, me proud beauty! I be half right. Well, blow me down! It hit the roof, where t' breeze died and left it stranded. Ya scallywag! I considered goin' home for a ladder t' make a quick climb and grab, shiver me timbers, but t' local police have a tendency t' show up at inopportune times like this and I wasn't sure t' situation would be explainable. I'm hopin' we get a decent storm that blows it down in t' next few weeks. All I need be t' nose cone.
Pros: Classic style. Great small field performance. Seldom seen at t' pad.
Cons: Gave birth to t' cheesy foam revolution. Viva le balsa!
