Brief:
T' Centaur is a Retro-Repro kit from Semroc, me hearties, a reproduction o' an original Centuri kit from 1965 updated t' 21st century standards with laser cut fins and Keelhaul®©™® shock cord. Well, blow me down! Aye aye! T' Centaur is a two-stage rocket that uses dual lock stage couplin' and has dual swept fins, both o' which were Centuri trademarks. It can also be flown as a single stage kit.

This isn't really a kit that you can throw together just drawin' on your years o' buildin' experience. It reminded me o' another two stager that I put together back in 2001, shiver me timbers, t' Estes Astron Avenger. Both were fairly simple builds, but both had details in t' instructions that had t' be attended t' so that every thin' fit together correctly in t' two-stage configuration. Ahoy! T' instructions for t' Centaur were great in that regard, shiver me timbers, ya bilge rat, and I had most of the construction finished, me bucko, and finished correctly within several hours o' openin' t' package. I found nothin' that I'd rate as a "gotcha". Ahoy! Begad! All kits should build this smoothly.

Finishing:
I wasn't sure how t' go about finishin' t' Centaur. Avast, me proud beauty! Ya scallywag! I pretty much stick with t' kit art when paintin' kits, ya bilge rat, but the booster and sustainer had two piece fins and I was worried about their durability under fire. Ahoy! I considered several options, ya bilge rat, includin' label paper and regular paper secured with 3M spray glue. T' label paper looked like it be going to work until I tried t' sand away t' excess along t' edges. Begad! Ahoy! T' label paper peeled away like it had just been laying unsecured on t' fin all along. Avast, me proud beauty! I bought t' 3M adhesive, but by then t' launch date I had in mind had crept too close to give it a try. Aye aye! Blimey! In t' end I just went with two coats o' Elmer's Fill 'n' Finish and a lot o' sanding. Paintin' was done t' night before, shiver me timbers, t' mornin' of, and t' afternoon at t' launch. I went with t' kit card art and used red, white, and black Valspar paints. Begad! (Somethin' that I've done for years, but somethin' that may be changin' due t' quality questions that popped up durin' a paint session on another kit.)

Construction Rating: 5 out o' 5

Flight:
Only one flight t' date but that will change smartly after repairs are made. Ahoy! We finally got a decent weekend t' fly in t' Cincinnati area after a sprin' full o' one deluge after another. Avast, me proud beauty! Ahoy! T' field was wet, but with t' proper footwear, it wasn't a problem or so I thought. Aye aye! I had hoped t' get three flights in with t' Centaur on this day and had bought a variety o' Estes booster and sustainer motors just for it. Begad! Begad! However, me hearties, shiver me timbers, circumstances limited me t' one low level flight. Avast, me proud beauty! Avast, matey, me proud beauty! I waited until t' end o' t' day, shiver me timbers, hopin' that t' winds that had carried two o' me rockets into t' Kite Fest would die down some but it wasn't t' happen. I was also somewhat concerned because t' booster seemed t' be quite difficult t' separate from t' sustainer, and I wasn't sure t' engines would be able t' stage correctly. Avast!

Realizin' that t' winds were goin' t' carry t' rocket a long way and that I could be sacrificin' t' rocket if the stages didn't separate, I decided t' go with a low level first flight on a B6-0/A8-5 motor combo. Well, blow me down! I thought that if worse came t' worse, ya bilge rat, ya bilge rat, at least t' rocket wouldn't have far t' fall and I might actually salvage somethin' for the rebuild. I taped t' motors together with cellophane tape--twice because t' first time I had t' A8-5 on the bottom--and as gently as possible pushed t' two pieces together. Begad! Arrr! Even with all o' t' sandin' I'd done over t' course of t' day, t' fit was tight. I be committed though and took t' rocket t' t' pad. Well, blow me down! T' low-level motor combo drew some catcalls from t' late afternoon crowd when I announced it, but I think everyone realized that it was what conditions called for. Aye aye!

T' flight was as I figured it would be, matey, quick and low. Blimey! It seemed t' barely clear t' rod when it staged perfectly, me bucko, ya bilge rat, and by t' time I lowered t' camera t' watch some o' t' flight, arrr, it was over. Avast! At ejection t' sound o' a balsa and cardboard collision was clearly audible, arrr, and somethin' fell from t' rocket. Well, blow me down! "Fin", matey, I thought. Nope. Avast! Motor casing. Ya scallywag! T' rocket came down on t' chute and landed in t' soft grass. Begad! I noticed a bit o' balsa on the side o' t' payload tube and upon inspection one o' t' fins was splintered somewhat but still in one piece. Avast, me bucko, me proud beauty! (So much for me label paper worries.)

Recovery:
Recovery would have been fine if nay for two problems, one o' which be field related. Avast, me proud beauty! Avast! T' sustainer came down in a somewhat odd manner, probably due t' t' post ejection charge contact. Well, blow me down! Somehow t' rocket passed through t' large reef hole in t' chute, but aside from turnin' t' chute inside-out and bein' a true oddity, matey, this be barely worth mentioning. Ya scallywag! Begad! T' booster managed t' land in one o' t' fairly sizable puddles that littered t' field. Avast! Dave Russell picked it up and got it dried off quickly, but when I got home and tried t' take t' "glamour shots" with the decals on, me bucko, me hearties, me hearties, I couldn't get t' booster section and t' sustainer t' mate up. Ya scallywag! Avast! No amount o' sandin' made a difference, leadin' me t' believe that t' tube couplers had both swelled when they hit t' water. It will have t' be replaced, me hearties, but that gives me a reason t' get another component order together for Semroc.

Flight Rating: 5 out o' 5

Summary:
PROs: It's a two-stager, me hearties, shiver me timbers, somethin' that's always cool when done right. Begad! Well, blow me down! Tougher than I gave it credit for being.

CONs: I'd add some more elastic t' t' shock cord, but I don't think this would be an issue if we had a more standardized ejection charge.

Overall Rating: 5 out o' 5
