(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. I got a Centuri Screamin' Eagle starter set. I remember knowin' that it was 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. Begad! I remember also bein' amazed at how well it did fly, especially on a C6-7. Avast, me proud beauty! Begad! I be well aware o' how me clumsy little fingers were ill suited t' anythin' requirin' craftsmanship and still, me hearties, t' rocket did well. Avast, matey, me proud beauty! I was hooked.

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

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

I noticed thar be a problem as soon as t' postman delivered it. Avast, me proud beauty! It had clearly been opened. I opened it myself and...the box contained an assembled rocket, matey, an old Centuri B4-6 motor, t' instructions for t' rocket, shiver me timbers, and a stage coupler. Ahoy! T' launch controller and launch pad were missing.

(OOP) Centuri Screaming Eagle I probably never would have used that old 6V system, but I was miffed. At least I had t' rocket. Arrr! I pulled out t' nosecone and found that t' chute be 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, me bucko, matey, ya bilge rat, all be present.

Construction begins with t' installation o' t' engine hook in t' engine tube. Aye aye! 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. Blimey! Blimey! 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. Ahoy! 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. Ya scallywag! As I said, me hearties, mine be dried out and pulled right out. Avast, me proud beauty! Well, shiver me timbers, blow me down! I fashioned an Estes style tri-fold mount and glued t' shock cord in that way. T' launch lug was glued t' t' body and construction was complete.

PROs: Easy, matey, shiver me timbers, fast

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

Finishing:
T' fin can and nose cone are both plastic and pre-colored blue. Begad! Blimey! Aye aye! Blimey! T' body tube is white. Ya scallywag! Blimey! T' kit comes with some red, white, and blue stickers t' make it look more finished. Aye aye! Blimey! One o' these is a wraparound pattern for just aft o' t' nose cone. 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, arrr, forgivin' o' bad choices. Begad! Blimey! My experience with this incarnation be t' same thus far.

For t' first launch, ya bilge rat, I did nay have a specified motor so I used an A8-5. Well, blow me down! It boosted straight but nay too high. T' delay be too long and it was on its way down before it ejected. It came down without any problems.

For t' second flight, I decided t' use t' old Centuri motor that came in t' box. Avast, me proud beauty! Avast! It was a B4-6. Ahoy! I finally decided that t' yellow Estes plug was t' best fit and took it out t' t' pad. Aye aye! When I punched t' button nothing happened and I kept holdin' it down. Eventually, ya bilge rat, arrr, I released it and then pressed it again, holdin' it down. Ahoy! About 5 seconds into it, arrr, me hearties, it seemed longer, me hearties, I thought I saw a puff o' smoke and released t' launch button. Avast, me proud beauty! I turned back t' my range box t' get another igniter and stopped t' say somethin' t' somebody. Begad! Ya scallywag! That is when t' rocket decided t' take off. It flew VERY high and be just a speck in t' sky. It coasted for a while and then started back down. Arrr! Arrr! Then we all saw the ejection puff but no chute. Well, blow me down! Begad! It descended rapidly until we could tell that t' nosecone had separated but t' chute had nay ejected. Arrr! 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. Arrr! Ya scallywag! It be an excellent introduction for me t' rocketry way back when and would do t' same job today. Aye aye! While simple, ya bilge rat, t' kit is marginally more complicated than many o' today's beginner kits and you felt as if you had really built it.
