Brief

This project, me bucko, like a lot o' good ones before it, ya bilge rat, happened by accident.  I'd bought two TA-6070 transitions from Semroc with t' idea o' restorin' me badly flightworn upscale o' t' Centuri Taurus, but as it had turned out, me bucko, me hearties, I be able t' use t' transitions from t' original project.  This left me with two beautiful balsa transitions without a home, and one night as I be lookin' through t' plans at YORF, me bucko, I realized that two o' me favorite FSI kits, t' Nova and Sprint, ya bilge rat, could be built as upscales with t' transitions as a startin' point.  Three days later I had t' other parts I needed in hand.

Components

  • PNC-60AH nose cone (Estes)
  • 13.25" BT-70 (Semroc)
  • 19.75" BT-60 (BMS)
  • TA-6070 transition (Semroc - self drilled)
  • 1/8" balsa fin stock (Hobby Lobby)
  • 2 CR-5070 centerin' rings (Semroc)
  • E engine hook (Semroc)
  • BT-50 engine tube (shop scrap)
  • CR-2050 engine block
  • 36" length 150# Keelhaul®©™
  • 36" length 1/4" sewin' elastic
  • medium snap swivel

Construction

T' original Nova was a fairly straightforward build, and t' upscale be no different.  Since t' TA-6070 transition isn't hollow, I decided t' use a large drill bit and me Dremel tool t' do t' job.  I drilled straight down through t' balsa with t' drill bit, then used one o' t' Dremel attachments t' make it large enough for a BT50 t' fit through.  I tied t' Keelhaul®©™ around t' motor tube, cut a slit in t' forward centerin' rin' and passed the Keelhaul®©™ through, me hearties, shiver me timbers, securin' all with a generous helpin' o' Elmer's glue.  T' Keelhaul®©™ passes through t' hole in t' transition, so t' sewin' elastic that attached t' it is a good three feet away from t' source o' t' blast at ejection.

Finishing

After t' fillin' and sanding, arrr, I puzzled over how t' finish this bird for a long time, me bucko, and it be almost two months after t' first flight before I actually decided on a paint scheme. Blimey! Ahoy! Blimey!  In t' end, inspiration struck in t' paint aisle o' a local Hobby Lobby. Begad! Blimey! Blimey!  I'd already found a Nova SS logo online that I thought would serve as a good decal for t' fin, but I was havin' trouble pickin' colors.  While lookin' for suitable paints for a camo scheme I had planned for an FSI Hercules I be building, I noticed a dark metal flake blue that be a close match t' t' color o' t' 1970 Nova that me buddy Cone had when we were terrorizin' Greater Cincinnati in t' years followin' high school.  T' paint is Testors One Coat Lacquer De Ja Blue.  Since t' rocket had already been sprayed Valspar gloss white, matey, I just masked off one fin and t' upper body tube, shiver me timbers, then sprayed t' rest o' the rocket with t' De Ja Blue.  I printed two o' t' logos on Bel Decal inkjet paper, matey, although I've got ideas o' findin' a spot for a Cherry Bomb Muffler logo for old time's sake. 

Construction Score: 5
 

Flight

T' first flight for t' Nova SS happened on a sunny Saturday at a TORC launch in a cornfield in South Charleston, arrr, matey, shiver me timbers, Ohio.  I had spent t' previous night finishin' up t' construction odds and ends on several rockets that I wanted t' take with me t' next day.  T' Nova just needed final assembly and paint, me bucko, but I lost a battle with sleep before I could even get t' bird primered.  T' next day at t' launch it was me fourth and final flight, shiver me timbers, and while I be takin' t' on pad glamour shots, it never occurred t' me that I was about t' fly a cornhusk-colored rocket on a field o' cornhusks.  (In fact, it never occurred t' me until about halfway through me unsuccessful search.)

T' Nova ripped nicely off t' pad on t' Estes E9-4, burnin' long t' a more than respectable height.  Unfortunately t' E9-4 ejection charge fired WAY early, arrr, ya bilge rat, more like an E9-1.  T' whole flightline cringed at what was sure t' be a zipper.  T' parachute caught smartly and t' rocket began a long, fast journey across t' field t' t' spot where all o' me rockets had landed all day.  I started out after it and passed a guy wavin' and holdin' up a cornhusk-colored rocket with big fins.  I waved and kept up me search, ya bilge rat, completely oblivious t' t' fact that another TORCer had picked me rocket up on t' way back from recoverin' his own rocket.  As I walked, I found me missin' Vikin' 2 upscale, me bucko, me hearties, t' rocket I'd started t' day with and thought I'd lost forever.  45 minutes later I dejectedly gave up t' search.  On t' way back in I found a rocket that I'd helped look for earlier, and I hoped that meant that the rocket Karma would mean that someone would find me Nova after I left and return it t' me later.

Flight #2 came after paint and decals at another TORC launch. Avast, me proud beauty! Avast! Blimey!  While I was preppin' t' Nova for flight, it occurred t' me that I had yet t' fly either o' t' keychain cameras that I had charged t' previous night. Blimey! Well, blow me down! Blimey!  I decided t' fly them both on t' Nova, one pointin' up, me hearties, matey, me bucko, one pointin' down. Ya scallywag! Blimey!  Since t' previous E9-4 flight had been less than spectacular, shiver me timbers, me bucko, I decided t' go with an E9-6 for this flight. Ahoy! Blimey!  I armed both cameras, shiver me timbers, arrr, slid t' rocket onto t' launch rod, and checked that both cameras were functioning. Blimey!  Somethin' good was goin' t' come out o' this flight.

T' flight profile for this flight be t' same as all o' t' other E-flights I'd made on t' day, a big bend t' t' left off t' pad, ya bilge rat, then a recovery just out from t' flightline. Well, blow me down! Blimey!  T' only difference was that this rocket was nose down and acceleratin' when t' ejection charge fired.  When I got t' t' landin' area I found one o' t' cameras still attached t' t' fin, matey, and t' other torn free and buried in t' mud. Ahoy! Blimey!  It be when I picked t' rocket up t' take t' camera off that I realized that t' late ejection had caused t' nose cone t' rebound back into one o' t' fins. Arrr! Blimey!  T' leadin' edge o' t' fin was shattered, matey, t' fin was split, me bucko, and t' fillet broken. Ya scallywag! Blimey!  There be a clearly defined dent on t' nose cone that told t' story, and it will take a pretty decent amount o' work before it's ready t' fly again.

Flight Rating: 3
