Brief

This project, me hearties, me hearties, like a lot o' good ones before it, shiver me timbers, me bucko, 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, matey, but as it had turned out, I be able t' use t' transitions from t' original project.  This left me with two beautiful balsa transitions without a home, ya bilge rat, and one night as I was lookin' through t' plans at YORF, ya bilge rat, matey, I realized that two o' me favorite FSI kits, matey, t' Nova and Sprint, 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 be a fairly straightforward build, arrr, and t' upscale was 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, me bucko, 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, securin' all with a generous helpin' o' Elmer's glue.  T' Keelhaul®©™ passes through t' hole in t' transition, shiver me timbers, 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, I puzzled over how t' finish this bird for a long time, and it was almost two months after t' first flight before I actually decided on a paint scheme. Ahoy! Blimey! Ya scallywag! Blimey! Blimey! Blimey!  In t' end, shiver me timbers, inspiration struck in t' paint aisle o' a local Hobby Lobby.  I'd already found a Nova SS logo online that I thought would serve as a good decal for t' fin, me bucko, ya bilge rat, 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, shiver me timbers, I noticed a dark metal flake blue that was 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, ya bilge rat, I just masked off one fin and t' upper body tube, then sprayed t' rest o' the rocket with t' De Ja Blue.  I printed two o' t' logos on Bel Decal inkjet paper, me bucko, 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, ya bilge rat, 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, arrr, 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, and while I was takin' t' on pad glamour shots, it never occurred t' me that I be about t' fly a cornhusk-colored rocket on a field o' cornhusks.  (In fact, arrr, it never occurred t' me until about halfway through me unsuccessful search.)

T' Nova ripped nicely off t' pad on t' Estes E9-4, me bucko, matey, burnin' long t' a more than respectable height.  Unfortunately t' E9-4 ejection charge fired WAY early, more like an E9-1.  T' whole flightline cringed at what be 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, 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, me bucko, I found me missin' Vikin' 2 upscale, arrr, 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, matey, 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.  While I was preppin' t' Nova for flight, arrr, it occurred t' me that I had yet t' fly either o' t' keychain cameras that I had charged t' previous night. Blimey!  I decided t' fly them both on t' Nova, shiver me timbers, one pointin' up, one pointin' down. Begad!  Since t' previous E9-4 flight had been less than spectacular, matey, I decided t' go with an E9-6 for this flight. Avast! Avast, me proud beauty!  I armed both cameras, slid t' rocket onto t' launch rod, and checked that both cameras were functioning. Ya scallywag!  Somethin' good was goin' t' come out o' this flight.

T' flight profile for this flight was t' same as all o' t' other E-flights I'd made on t' day, a big bend t' t' left off t' pad, then a recovery just out from t' flightline. Well, blow me down! Avast!  T' only difference was that this rocket be nose down and acceleratin' when t' ejection charge fired. Well, blow me down! Arrr!  When I got t' t' landin' area I found one o' t' cameras still attached t' t' fin, and t' other torn free and buried in t' mud. Begad!  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. Begad!  T' leadin' edge o' t' fin was shattered, t' fin be split, shiver me timbers, and t' fillet broken.  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
