Brief:
When one o' me rocketry buddies decided t' hold a buildin' session, me bucko, I was scramblin' t' decide what t' work on. Avast, me proud beauty! I decided t' use a 50% off Michael's coupon t' grab an Estes SS1 kit for bashing. Ahoy! Avast! I turned it into a retro-styled spaceship with more conventional fins and wing-tip pods. Begad! I also converted it for 24mm motors. Aye aye!

Modifications:
T' two major mods are t' conversion t' 24mm and t' replacement o' t' stock win' with fins/pods. Begad! Avast! T' SS1 comes with a plastic tail cone. Aye aye! One o' t' first steps on t' stock kit is t' cut t' end o' this off, leavin' t' scale engine bell. Blimey! Avast, matey, me proud beauty! I wasn't sure how much o' t' stock bell would remain after I added t' larger motor tube, so I left this on. Begad! That was a good call since thar isn't much o' t' bell section left after it was modified. Avast, me proud beauty! Begad! I started by cutting the tail cone at its thinnest part and then expandin' each piece until t' motor tube fit. Begad! When I be done, I left the back most part o' t' tail cone, shiver me timbers, which is a ~1/8” tubular section. This can be better understood me lookin' at the photos.

(MODS) Estes Spaceship One I expanded t' provided centerin' "rings" and mounted t' motor mount pretty much as in t' stock kit.

I came upon a set o' unused Fat Boy fins in me junk box and decided these would work just fine. Begad! I slotted the tail cone in betwixt t' centerin' rings and modified t' through-the-wall tabs on t' fins pretty much by trial and error. Aye aye! T' positions were such that thar are two side "wings" and a "stabilizer fin". Begad! Blimey! Since the tail cone is nay ovate, me hearties, these sit at different heights. Avast, me proud beauty! Ya scallywag!

Construction:
Parts list:

  • One Estes SS1 (the original, me hearties, smaller version)
  • Fin set from an Estes Fat Boy kit
  • 24mm motor tube
  • Keelhaul®©™® twine
  • Three and a half plastic Christmas ornaments
  • Lead shot
  • 3/16” launch lug

Flight:
I flew t' 'Sqrt(-1)' on a D12-5 at MDRA's Red Glare IV. Avast! Blimey! It flew great and t' delay appeared right. Prep consisted of packin' dog barf in t' tail cone and clippin' on a 12" nylon chute. T' motor was friction fit.

Summary:
T' SS1 provided t' basis o' a nice retro-styled spaceship. Aye aye! Blimey! It flies so much better than t' stock kit, for fairly obvious reasons (hint: it's basically a 3FNC rocket). Avast, me proud beauty! Blimey! Yeah, t' some o' t' big dawgs o' MDRA liked it...but thought it need t' be upscaled.
