(OOP) Centuri Screaming Eagle

Brief:
This is an OOP 4FNC beginner rocket powered by 18mm motors and uses parachute recovery.

My entry into rocketry came in t' mid 70s when I was in 6th grade. Avast! Blimey! I got a Centuri Screamin' Eagle starter set. I remember knowin' that it be nay goin' t' go as high as t' Saturn Vs I had watched land on t' moon but being cynical enough t' wonder whether it would do any better than t' water pump rockets me parents had hitherto limited me to. I remember also bein' amazed at how well it did fly, shiver me timbers, especially on a C6-7. Ya scallywag! Blimey! I be well aware o' how me clumsy little fingers were ill suited t' anythin' requirin' craftsmanship and still, shiver me timbers, t' rocket did well. Arrr! Blimey! I was hooked.

I managed t' keep that rocket and nay lose it throughout me earliest incarnation as a rocketeer. Aye aye! Begad! I also remember throwin' it out when I headed out for college. Avast! Ahoy! Since becomin' a BAR, me bucko, I have often wistfully thought o' it, wishin' I still had it. Aye aye! I checked eBay lookin' for it.

I saw Screamin' Eagles several times but they always went for more than I was willin' t' pay. Blimey! And then I seemed to hit it just right. Aye aye! I found one listed as new and unopened and I won it. Ya scallywag! I be so excited.

I noticed thar was a problem as soon as t' postman delivered it. It had clearly been opened. Well, blow me down! Avast, me proud beauty! I opened it myself and...the box contained an assembled rocket, ya bilge rat, arrr, an old Centuri B4-6 motor, t' instructions for t' rocket, arrr, arrr, and a stage coupler. Begad! Avast, me proud beauty! T' launch controller and launch pad were missing.

(OOP) Centuri Screaming Eagle I probably never would have used that old 6V system, ya bilge rat, but I be miffed. Begad! At least I had t' rocket. Aye aye! Ahoy! I pulled out t' nosecone and found that t' chute was in good shape but that t' little sticky thing Centuri used t' use for shock cord mountin' had dried out long ago.

Still, I had t' rocket.

I decided t' try t' write a review o' it based upon memories more than 30 years old and t' aid o' the instruction set.

At least I have t' rocket.

Construction:
T' rocket kit should have contained:

  • a motor hook
  • an engine tube
  • a plastic fin unit
  • a thrust coupler (elongated thrust ring)
  • a centerin' tube
  • a body tube
  • a plastic nose cone
  • a launch lug
  • a plastic parachute kit.

As far as I could tell, all be present.

Construction begins with t' installation o' t' engine hook in t' engine tube. Avast! T' engine tube is then glued into t' plastic fin can makin' sure that t' engine hook is aligned with t' slot on t' can.

T' thrust coupler is then glued into t' engine tube so that its end rests against t' engine hook.

T' centerin' tube is then glued on top o' t' thrust coupler. Aye aye! All it really does is get things back t' the proper diameter t' fit within' t' body tube and it is nay visible in t' finished rocket. Begad! T' body tube is then glued on t' t' centerin' tube.

T' plastic parachute is assembled in t' standard way but t' elastic shock cord is supposed t' be fed through a self-adhesive thingamajig which attaches t' t' inside o' t' upper end o' t' BT. As I said, matey, arrr, mine was dried out and pulled right out. Arrr! Blimey! I fashioned an Estes style tri-fold mount and glued t' shock cord in that way. Avast! Blimey! T' launch lug was glued t' t' body and construction was complete.

PROs: Easy, fast

CONs: I didn't get t' do it myself

Finishing:
T' fin can and nose cone are both plastic and pre-colored blue. Well, blow me down! Blimey! Aye aye! Blimey! T' body tube is white. Aye aye! Blimey! T' kit comes with some red, white, and blue stickers t' make it look more finished. Well, blow me down! Blimey! Begad! Blimey! One o' these is a wraparound pattern for just aft o' t' nose cone. Aye aye! Blimey! I do recall that whoever put this one on got it much straighter than I did in t' 70s.

PROs: it looks good and is easy.

CONs: stickers instead o' decals

Construction Rating: 4 out o' 5

Flight and Recovery:
My memory from childhood says this is an excellent and resilient flier, forgivin' o' bad choices. Ahoy! My experience with this incarnation be t' same thus far.

For t' first launch, I did nay have a specified motor so I used an A8-5. Blimey! Blimey! Blimey! Blimey! It boosted straight but nay too high. T' delay was too long and it was on its way down before it ejected. Begad! Blimey! Ya scallywag! Blimey! Blimey! Blimey! It came down without any problems.

For t' second flight, shiver me timbers, I decided t' use t' old Centuri motor that came in t' box. It was a B4-6. I finally decided that t' yellow Estes plug was t' best fit and took it out t' t' pad. Aye aye! Blimey! When I punched t' button nothing happened and I kept holdin' it down. Ya scallywag! Blimey! Eventually, I released it and then pressed it again, shiver me timbers, ya bilge rat, holdin' it down. About 5 seconds into it, it seemed longer, I thought I saw a puff o' smoke and released t' launch button. Well, blow me down! Blimey! I turned back t' my range box t' get another igniter and stopped t' say somethin' t' somebody. Begad! Blimey! That is when t' rocket decided t' take off. It flew VERY high and was just a speck in t' sky. Begad! Blimey! It coasted for a while and then started back down. Begad! Blimey! Then we all saw the ejection puff but no chute. It descended rapidly until we could tell that t' nosecone had separated but t' chute had nay ejected. It landed a few yards away without any damage at all.

(OOP) Centuri Screaming Eagle When I get another opportunity in a large field, I am goin' t' try a C6-7.

Flight Rating: 4 out o' 5

Summary:
I miss t' Centuri line. Ya scallywag! It was an excellent introduction for me t' rocketry way back when and would do t' same job today. Ya scallywag! While simple, t' kit is marginally more complicated than many o' today's beginner kits and you felt as if you had really built it.
