Estes FirebirdBrief:
This is a father/son dual build. Well, blow me down! Up t' this point, I've been helpin' him build his rockets. 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, shiver me timbers, he's been doin' more and more, and t' roles are reversin' where I'm becomin' t' extra hands. Begad! I found a couple o' Firebirds for relatively cheap, me hearties, shiver me timbers, arrr, and so we're buildin' these in parallel. Aye aye! This will be his first purely solo build, arrr, and we'll be comparin' t' results o' our two builds. Avast! Avast! After this, ya bilge rat, ya bilge rat, he'll be movin' on t' buildin' his L1 cert rocket... Begad! if I think he's ready.

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

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

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

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

Namely t' recovery section.

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

Speakin' o' which, arrr, shiver me timbers, I wonder why Estes went with through t' wall fins for this kit and only an 18mm mount. Aye aye! Blimey! For all t' Estes 18mm motors, TTW fins is way overkill. Arrr! Blimey! Aye aye! Blimey! O' course, arrr, me bucko, it does make fin alignment much easier.

Son: Well, he taught me, ya bilge rat, so, yeah, me bucko, I'm tossin' t' 3-fold as well. Since I'm doin' t' 24mm thing, ya bilge rat, matey, I get t' choose me engine tube size, me hearties, so I went with a longer tube, and a third centerin' ring. Arrr! Well, blow me down! 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. Ya scallywag! Hah! Mines stronger.

While I was at it, me bucko, I cut t' top o' t' engine hook off so it doesn't go into t' motor tube. Ya scallywag! Begad! I also left off t' motor block. 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. T' up side is that I can use any 24mm motor includin' t' upcomin' Aerotech 24/120 and t' CTI Pro 24 cases. Ya scallywag! Ya scallywag! Bigger, faster, ya bilge rat, 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. Maybe, matey, shiver me timbers, but it's fun. Begad! Besides, shiver me timbers, I don't pay for t' motors. (Dad: He may start buyin' them if he loses them like this)

Finishing:
Dad: Decals are typical o' Estes in this era. Begad! That means peel and stick. Begad! I really don't like them. Aye aye! I much prefer water slide. Blimey! Well, blow me down! That said, as per me usual superstitious approach, matey, I won't actually paint and decal t' rocket until after t' first few flights. Ya scallywag! 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. Avast! Ya scallywag! If I build a rocket in 2 hours t' night before a launch, ya bilge rat, it's comin' back. Avast, me proud beauty! Arrr! Every time I've spent 2-3 months doin' a painstakin' job o' buildin' and finishing, somethin' bad has happened.

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

Son: I'm done building, let's go fly. Ahoy! Blimey! Blimey! Blimey! Seriously. Well, blow me down! Blimey! Blimey! Blimey! Yeah, I could take some time t' make it look good, me bucko, me bucko, shiver me timbers, but this isn't one o' those rockets. Let's fly. 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, arrr, ya bilge rat, we keep a supply o' Nomex t' avoid usin' wadding. Begad! Waddin' can be easier in t' smaller rockets, but t' larger ones just take too much. Besides, shiver me timbers, reuseable Nomex is more eco friendly.

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

Son: What he said. I'm gettin' tired o' typing. Blimey! I haven't flown mine yet. Aye aye! Weather hasn't been good enough.

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

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