Brief:
T' Centaur is a Retro-Repro kit from Semroc, shiver me timbers, me bucko, a reproduction o' an original Centuri kit from 1965 updated t' 21st century standards with laser cut fins and Keelhaul®©™® shock cord. 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, t' Estes Astron Avenger. Begad! Both were fairly simple builds, ya bilge rat, 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. Begad! T' instructions for t' Centaur were great in that regard, and I had most of the construction finished, and finished correctly within several hours o' openin' t' package. I found nothin' that I'd rate as a "gotcha". All kits should build this smoothly.

Finishing:
I wasn't sure how t' go about finishin' t' Centaur. Ya scallywag! I pretty much stick with t' kit art when paintin' kits, me bucko, but the booster and sustainer had two piece fins and I be worried about their durability under fire. I considered several options, includin' label paper and regular paper secured with 3M spray glue. Avast, me proud beauty! Begad! T' label paper looked like it was going to work until I tried t' sand away t' excess along t' edges. Well, blow me down! T' label paper peeled away like it had just been laying unsecured on t' fin all along. Avast! Blimey! I bought t' 3M adhesive, me hearties, matey, matey, but by then t' launch date I had in mind had crept too close to give it a try. Avast! Arrr! In t' end I just went with two coats o' Elmer's Fill 'n' Finish and a lot o' sanding. Arrr! Paintin' was done t' night before, t' mornin' of, and t' afternoon at t' launch. Well, blow me down! I went with t' kit card art and used red, white, and black Valspar paints. Avast, me proud beauty! Ahoy! (Somethin' that I've done for years, me hearties, 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. We finally got a decent weekend t' fly in t' Cincinnati area after a sprin' full o' one deluge after another. T' field was wet, but with t' proper footwear, arrr, me bucko, it wasn't a problem or so I thought. Ahoy! Ahoy! 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. However, circumstances limited me t' one low level flight. Aye aye! I waited until t' end o' t' day, arrr, 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, arrr, and I wasn't sure t' engines would be able t' stage correctly. Ya scallywag!

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. Blimey! I thought that if worse came t' worse, at least t' rocket wouldn't have far t' fall and I might actually salvage somethin' for the rebuild. Avast, me proud beauty! Avast, me proud beauty! 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. Ya scallywag! Even with all o' t' sandin' I'd done over t' course of t' day, matey, t' fit was tight. Ahoy! Begad! I be committed though and took t' rocket t' t' pad. Arrr! Well, blow me down! T' low-level motor combo drew some catcalls from t' late afternoon crowd when I announced it, me hearties, but I think everyone realized that it was what conditions called for. Aye aye! Ya scallywag!

T' flight be as I figured it would be, quick and low. Avast, me proud beauty! Blimey! It seemed t' barely clear t' rod when it staged perfectly, me hearties, and by t' time I lowered t' camera t' watch some o' t' flight, shiver me timbers, it was over. Blimey! Aye aye! At ejection t' sound o' a balsa and cardboard collision be clearly audible, and somethin' fell from t' rocket. "Fin", I thought. Nope. Blimey! Motor casing. T' rocket came down on t' chute and landed in t' soft grass. Avast! 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. Well, blow me down! Ahoy! (So much for me label paper worries.)

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