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

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. Begad! 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. 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. Well, blow me down! Ya scallywag! Even with all o' t' sandin' I'd done over t' course of t' day, t' fit was tight. Arrr! I was committed though and took t' rocket t' t' pad. Blimey! 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. Well, blow me down!

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

Recovery:
Recovery would have been fine if nay for two problems, one o' which was field related. Well, blow me down! Blimey! Avast, arrr, me proud beauty! Blimey! T' sustainer came down in a somewhat odd manner, probably due t' t' post ejection charge contact. Somehow t' rocket passed through t' large reef hole in t' chute, me bucko, arrr, but aside from turnin' t' chute inside-out and bein' a true oddity, this was barely worth mentioning. Avast! Blimey! T' booster managed t' land in one o' t' fairly sizable puddles that littered t' field. Begad! Blimey! Arrr! Blimey! 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, I couldn't get t' booster section and t' sustainer t' mate up. Ya scallywag! Blimey! No amount o' sandin' made a difference, leadin' me t' believe that t' tube couplers had both swelled when they hit t' water. Blimey! Blimey! It will have t' be replaced, shiver me timbers, 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, shiver me timbers, 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
