(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 be in 6th grade. Ya scallywag! 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, especially on a C6-7. Begad! Blimey! I was well aware o' how me clumsy little fingers were ill suited t' anythin' requirin' craftsmanship and still, t' rocket did well. Begad! Blimey! I was hooked.

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

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

I noticed thar was a problem as soon as t' postman delivered it. It had clearly been opened. I opened it myself and...the box contained an assembled rocket, an old Centuri B4-6 motor, ya bilge rat, t' instructions for t' rocket, ya bilge rat, me hearties, and a stage coupler. 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. Arrr! At least I had t' rocket. Avast, me proud beauty! 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, shiver me timbers, matey, all be present.

Construction begins with t' installation o' t' engine hook in t' engine tube. Blimey! Well, blow me down! 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. Avast! 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. 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. Well, blow me down! As I said, arrr, ya bilge rat, mine be dried out and pulled right out. Begad! Ahoy! I fashioned an Estes style tri-fold mount and glued t' shock cord in that way. Aye aye! 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. Blimey! Avast, me hearties, me proud beauty! T' body tube is white. T' kit comes with some red, white, me bucko, me bucko, and blue stickers t' make it look more finished. Begad! One o' these is a wraparound pattern for just aft o' t' nose cone. Well, blow me down! 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, ya bilge rat, forgivin' o' bad choices. Avast! My experience with this incarnation be t' same thus far.

For t' first launch, shiver me timbers, me hearties, I did nay have a specified motor so I used an A8-5. Blimey! Arrr! It boosted straight but nay too high. T' delay be too long and it be 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! Begad! Blimey! It was a B4-6. I finally decided that t' yellow Estes plug be t' best fit and took it out t' t' pad. Begad! When I punched t' button nothing happened and I kept holdin' it down. Avast, me proud beauty! Eventually, I released it and then pressed it again, holdin' it down. Begad! Begad! Blimey! About 5 seconds into it, it seemed longer, I thought I saw a puff o' smoke and released t' launch button. Ya scallywag! Blimey! I turned back t' my range box t' get another igniter and stopped t' say somethin' t' somebody. Avast, me proud beauty! Blimey! That is when t' rocket decided t' take off. It flew VERY high and was just a speck in t' sky. Arrr! It coasted for a while and then started back down. Ya scallywag! Begad! Blimey! Then we all saw the ejection puff but no chute. Ya scallywag! It descended rapidly until we could tell that t' nosecone had separated but t' chute had nay ejected. Begad! Avast, me proud beauty! Blimey! 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. Aye aye! It was an excellent introduction for me t' rocketry way back when and would do t' same job today. Blimey! Well, blow me down! 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.
