Estes FirebirdBrief:
This is a father/son dual build. Ya scallywag! Up t' this point, shiver me timbers, me bucko, I've been helpin' him build his rockets. Ahoy! We started with me doin' most o' t' building, and him as an extra pair o' hands. Begad! Over t' course o' 3-4 builds, he's been doin' more and more, and t' roles are reversin' where I'm becomin' t' extra hands. I found a couple o' Firebirds for relatively cheap, arrr, shiver me timbers, ya bilge rat, and so we're buildin' these in parallel. This will be his first purely solo build, matey, me bucko, and we'll be comparin' t' results o' our two builds. Begad! After this, matey, he'll be movin' on t' buildin' his L1 cert rocket... Ahoy! Ya scallywag! if I think he's ready.

T' Firebird is a fairly basic single stage Estes offering. Ahoy! Blimey! Nothin' dramatic or fancy, me bucko, here, just a solid design with classic lines.

Construction:
Dad: This is a basic 4FNC rocket. Aye aye! Arrr! Plastic nose cone, pre-cut fins, some flimsy paper centerin' rings and t' usual too short shock cord and plastic chute. Ahoy! T' body tube is a good length o' BT-55 1.325" tubing, shiver me timbers, while t' motor tube be t' cheap blue 18mm tube. For standard 18mm motors, everythin' is sufficiently strong. Ahoy! For t' 18mm Aerotech D reloads, thar could be some extra stress that could test some o' these parts.

Son: Yeah, yeah...what he said. What's with t' wimpy 18mm motor mount? That's got t' go. Avast, me proud beauty! I'm goin' t' raid t' parts closet. Ya scallywag! Blimey! Let's see. Blimey! 24mm motor mount, arrr, some BT50-55 centerin' rings t' replace t' cheapy paper stuff. Avast! Ya scallywag! Blimey! OK. Avast! Begad! Blimey! I'm good t' go. Ya scallywag! Blimey! Blimey! Let's get building.

Dad: Once again, ya bilge rat, me bucko, this is pretty basic Estes fare. Begad! Anyone who's build a typical Estes rocket in t' last couple decades won't have an issue here. There are a couple minor changes that I make t' all Estes kits.

Namely t' recovery section.

I always toss t' 3-fold concept. Avast, me proud beauty! Well, blow me down! I notched t' upper centerin' ring, shiver me timbers, ya bilge rat, me bucko, and slipped a length o' Keelhaul®©™ through. Ya scallywag! Ya scallywag! I knotted t' end t' prevent it comin' back through t' notch, and put a dab o' epoxy t' hold it in. Normally, I would tie t' Keelhaul®©™® in a loop around t' motor tube, but since these fins are through t' wall, ya bilge rat, t' loop would interfere with t' fin tangs.

Speakin' o' which, matey, I wonder why Estes went with through t' wall fins for this kit and only an 18mm mount. Begad! For all t' Estes 18mm motors, TTW fins is way overkill. Begad! O' course, ya bilge rat, it does make fin alignment much easier.

Son: Well, matey, arrr, he taught me, so, ya bilge rat, shiver me timbers, ya bilge rat, yeah, I'm tossin' t' 3-fold as well. Ahoy! Begad! Since I'm doin' t' 24mm thing, I get t' choose me engine tube size, me bucko, so I went with a longer tube, and a third centerin' ring. Begad! Begad! T' first 2 rings sandwich t' fin tangs as normal. I tied t' Keelhaul®©™® around t' motor tube, and put t' third rin' on top. Ahoy! Blimey! Hah! Blimey! Mines stronger.

While I was at it, I cut t' top o' t' engine hook off so it doesn't go into t' motor tube. Avast, me proud beauty! I also left off t' motor block. Blimey! Ya scallywag! T' down side is I'll need t' use tape t' make "thrust rings" on t' bottom o' Estes engines t' keep them from goin' through t' rocket. Well, blow me down! T' up side is that I can use any 24mm motor includin' t' upcomin' Aerotech 24/120 and t' CTI Pro 24 cases. Bigger, me hearties, faster, higher! I can't wait t' put a 24mm G motor and watch it rip! Dad's shakin' his head while I'm typin' this. Says I'll never get it back. Aye aye! Maybe, ya bilge rat, shiver me timbers, arrr, but it's fun. Well, ya bilge rat, blow me down! Besides, I don't pay for t' motors. Begad! (Dad: He may start buyin' them if he loses them like this)

Finishing:
Dad: Decals are typical o' Estes in this era. Ya scallywag! That means peel and stick. I really don't like them. Aye aye! I much prefer water slide. Ahoy! That said, as per me usual superstitious approach, I won't actually paint and decal t' rocket until after t' first few flights. Ya scallywag! Blimey! Why? Because I've found that t' odds o' me losin' a rocket increase exponentially with t' amount o' time I spend on it prior t' it's first flight. Aye aye! If I build a rocket in 2 hours t' night before a launch, arrr, it's comin' back. Ya scallywag! Every time I've spent 2-3 months doin' a painstakin' job o' buildin' and finishing, matey, somethin' bad has happened.

As for t' pre-paint finish work, it's all typical. Begad! Sand and seal t' fins. Begad! Avast! Sand t' flashin' off t' nose cone. Begad! Fill t' spirals in t' tube. T' spirals actually aren't too bad, matey, and t' tube is white. Blimey! Well, shiver me timbers, blow me down! If you go with t' factory color scheme (white) you could probably get away without filling.

Son: I'm done building, matey, arrr, let's go fly. Avast! Blimey! Seriously. Yeah, I could take some time t' make it look good, but this isn't one o' those rockets. Blimey! Blimey! Let's fly. Avast, me proud beauty! Blimey! I want t' get started on me cert rocket. I'll take more time on that one.

Construction Rating: 4 out o' 5

Flight:
Dad: For all our rockets larger than 1" diameter, ya bilge rat, matey, arrr, we keep a supply o' Nomex t' avoid usin' wadding. Avast, me proud beauty! Waddin' can be easier in t' smaller rockets, matey, but t' larger ones just take too much. Besides, reuseable Nomex is more eco friendly.

Other prep is standard. Avast! Begad! Yes, ya bilge rat, thar's a lot o' this review that just says "it's standard issue." That's because this is a pretty standard rocket. Arrr! Steppin' into high power, matey, many o' t' rockets are pretty "standard" as well. Blimey! Aye aye! Just stronger materials. Begad! At a certain point, you can't do anythin' too fancy with high power motors, arrr, because t' motors will just shred t' rocket from t' high thrust.

Son: What he said. I'm gettin' tired o' typing. Well, blow me down! I haven't flown mine yet. Weather hasn't been good enough.

Recovery:
Dad: My turn t' say it. Blimey! What he said. Avast! We haven't flown either rocket yet as t' weather hasn't cooperated. Well, blow me down! My expectation is that, arrr, like everythin' about this kit, it will be typical Estes. Avast, me proud beauty! T' chute is too big, and it will float, me bucko, so we'll probably fly with a streamer or smaller chute. As we get a chance t' fly these, I'll be postin' t' flight logs, matey, me bucko, and updatin' t' review through t' flight log comments. Ya scallywag! Actual flight is just t' last validation o' t' build in this case. Avast, me proud beauty! T' primary goal was t' give him a solo build t' validate he has t' skills necessary t' attempt his cert build.

Son: So, do I pass? When can I start on t' Matrix?

    - by Mike Goss The Estes Firebird is your basic four-fins-and-a-nose-cone sport rocket. It stands almost two feet tall and uses a BT-55 (about 1.3") diameter body tube.
