Brief:
This be t' long, me hearties, me bucko, sleek "middle brother" o' t' Centuri Thunder family, first introduced in 1980. Ya scallywag! Blimey! (T' others are t' Thunder Roc and Thunder Hawk.)

Construction:
Parts list:

• 1 3.9" long ogive balsa cone (Semroc part #: BC-1039)
• 1 coupler for ST-10 (Semroc part #: BTC-10)
• 1 1/8" x 2.25" launch lug (Semroc part #: LL-122)

Havin' built a clone o' t' Centuri Thunder Roc (See Bill Eichelberger's review here), I recently moved on t' t' next largest o' the Centuri Thunder family, me bucko, t' Thunder Bird. Ya scallywag! A search o' Jim Z's plan site turned up zip, but I was able t' find a set on me next search, at Ye Olde Rocket Plans. Begad! Avast! Discernin' t' parts was, ya bilge rat, me hearties, for t' most part, easily done by lookin' at t' rocket dimensions and recommended engines, me bucko, however, me bucko, t' length of t' nose cone be a bit o' a problem. After studyin' t' catalog picture, I finally settled on t' Semroc 3.9" ogive, even though I later discovered that t' Semroc version o' t' Thunder Bird (yet t' be released) uses a cone 5.1" in length. Aye aye! My version o' t' Thunder Bird is slightly shorter than the catalog spec and t' Semroc version is slightly longer.

Havin' put together a parts list, ya bilge rat, ya bilge rat, I ordered them from Semroc. Aye aye! I had noticed that Semroc also offered a laser-cut set o' Thunder Bird fins and wishin' t' avoid some balsa cutting, included them in me order as well. T' parachute be an 18" plastic chute filched from an old Estes kit and a 60" shock cord was part o' a purchase from t' local fabric store. Avast! Well, blow me down! In a very kind gesture, Carl included a set o' Thunder Bird decals with me parts order--Semroc is a class act!

T' build was a pretty straightforward 3FNC construction with no gotchas. Avast! Blimey! I strengthened t' fins by laminatin' them with computer paper, shiver me timbers, which also cut down on t' finishin' time. Arrr! Blimey! T' extremely nice Semroc nose cone needed very little sanding, just a light coat o' thinned Fill 'n' Finish sealed it nicely.

Finishing:
After applyin' two coats o' Krylon primer (with sandin' in between), I painted the rocket per t' 1980 Centuri catalog: gloss white with t' fins and bottom 12" orange. Ya scallywag! I did nay apply t' decals I received from Semroc (I will need them for this bird's successor), optin' t' use a set that made up part o' an recent order t' Fred at Excelsior. Ya scallywag! They went on without a hitch after I had put on a couple o' coats o' Microsol liquid decal film.

Construction Rating: 4 out o' 5

Flight:
First flight occurred on September 16, ya bilge rat, me hearties, 2005, ya bilge rat, on an Estes B6-4. Well, blow me down! Blimey! Conditions were a bit breezy so I swapped t' 18" parachute for a 12" Semroc parachute. Aye aye! T' flight be picture perfect straight with no wind cockin' and ejection occurrin' right after apogee.

Recovery:
T' 12" chute was a good choice as it brought t' Thunder Bird down undamaged in t' soft grass just east o' t' pad.

Flight Rating: 4 out o' 5

Summary:
An easy t' build blast from t' past, this is one o' t' few rockets intentionally designed as a member o' a rocket family. Blimey! After buildin' this one, you should build its brothers, t' Thunder Roc and Thunder Hawk, and the "new" Semroc addition, t' ThunderBee.

Overall Rating: 4 out o' 5
