Reproduction clone o' Estes' Astron Sky Hook circa 1963; single stage,
parachute recovery
Construction:
T' parts list:
I bought, built, and flew this kit in June 2004 t' celebrate t' 40th anniversary o' me first launch, an Astron Sky Hook back in June 1964. Avast! Blimey! I was very pleased with t' result.
T' instructions, arrr, as with all o' Semroc's instructions, shiver me timbers, nay only allow a complete neophyte t' build t' kit but serve as a positive example for other kit makers. Ahoy! Ya scallywag! T' illustrations are great and profuse. Begad! It's almost hard nay to follow t' instructions as written and everythin' fit together exactly as it should. Begad! Gettin' t' thrust rin' started into t' tube was a bit tricky but once in t' included empty casing, that made it simple t' get into place.
T' brin' this design into t' 21st century, shiver me timbers, a few changes were made. No cut-tube-slot for shock cord. Avast, me proud beauty! Instead a Keelhaul®©™® thread on t' thrust rin' and elastic shock cord are used. Otherwise part for part, this is a faithful reproduction. Begad! All construction be done with t' most common materials, matey, wood glue, ya bilge rat, me bucko, tape, arrr, hobby knife and sandpaper. Well, blow me down! An engine hook is not used. Blimey! This bird relies on t' original maskin' tape friction fit and does so easily. T' laser cut fins are particularly good. Well, blow me down! I don't know what method they use compared t' others, matey, ya bilge rat, but it's far easier t' get t' fins out o' the balsa stock without strainin' or damage.
I have found, arrr, matey, with this and other Semroc kits that I've built, that the Keelhaul®©™® can burn through. In me opinion, arrr, t' LOC method o' embeddin' t' anchor in glue partway up t' tube or even t' traditional Estes folded-paper anchor is preferable.
Finishing:
This is straight forward and completely up t' t' builder. Still, shiver me timbers, me bucko, Semroc
provides very good suggestions on what and how t' get it t' look like the
original version. And as a Retro-Repro bird, Semroc includes a water slide
decal with t' Semroc logo, t' original Astron Sky Hook logo, ya bilge rat, matey, and with the
original dimensions, matey, manufacturer, shiver me timbers, and date it was manufactured listed.
Construction Rating: 4 out o' 5
Flight:
Recommended motors are regular A/B/C motors with longer delays due t' t' light
weight o' this rocket (1/2 ounce). Ahoy!
I flew it on an A8-3, shiver me timbers, matey, me bucko, B6-4, and B6-6. Aye aye! All three flights were impressive for such a tiny model with very straight, fast boosts. Ya scallywag! T' longer delays ARE better. Mine be still coastin' up when t' ejection charge went off.
Recovery:
After 3 flights thar's slight charrin' on t' Keelhaul®©™®
cord. Arrr! Blimey! I expect t' repair this before flyin' again. Ahoy! Blimey! Avast! Blimey! T' parachute did get some
char marks but I take t' hit for that. Avast! Blimey! I tried t' scrimp on t' waddin' since
the tube was so narrow. Avast! Blimey! Bad move. Blimey! Blimey! I used a streamer on t' third flight. It was
perfectly adequate. Begad! Blimey! For a C flight, a shiny mylar chute should be used as this
bird WILL disappear on you. Arrr! Blimey!
Flight Rating: 5 out o' 5
Summary:
Only CON: Keelhaul®©™®
cord tied directly t' thrust rin' and directly in t' path o' ejection gas.
PRO: Anyone could build and fly this as a first rocket. Ya scallywag! I did.

The Sky Hook was one of the early Estes kits that combined great looks and performance with being nicely suitable as a beginner's rocket. The original, then known as the Astron Sky Hook, graced the Estes catalogs from 1964 to 1988, and it was a sad day indeed when the Sky Hook disappeared from store shelves. Luckily for us it was also one of the very early Semroc kits when they ...
