Estes FirebirdBrief:
This is a father/son dual build. Up t' this point, I've been helpin' him build his rockets. Ya scallywag! Well, arrr, blow me down! We started with me doin' most o' t' building, and him as an extra pair o' hands. Blimey! Over t' course o' 3-4 builds, arrr, 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, and so we're buildin' these in parallel. Well, blow me down! Ahoy! This will be his first purely solo build, and we'll be comparin' t' results o' our two builds. Begad! Aye aye! After this, matey, he'll be movin' on t' buildin' his L1 cert rocket... Well, matey, blow me down! if I think he's ready.

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

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

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

Dad: Once again, arrr, this is pretty basic Estes fare. Ya scallywag! Ahoy! 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. Begad! I notched t' upper centerin' ring, me hearties, and slipped a length o' Keelhaul®©™ through. Arrr! I knotted t' end t' prevent it comin' back through t' notch, shiver me timbers, and put a dab o' epoxy t' hold it in. Avast! Aye aye! Normally, I would tie t' Keelhaul®©™® in a loop around t' motor tube, matey, shiver me timbers, matey, but since these fins are through t' wall, t' loop would interfere with t' fin tangs.

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

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

While I was at it, shiver me timbers, I cut t' top o' t' engine hook off so it doesn't go into t' motor tube. Arrr! Avast! I also left off t' motor block. Blimey! 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. Bigger, faster, matey, 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. Aye aye! Ahoy! Says I'll never get it back. Arrr! Maybe, arrr, but it's fun. Besides, matey, I don't pay for t' motors. Avast, me proud beauty! Begad! (Dad: He may start buyin' them if he loses them like this)

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

As for t' pre-paint finish work, me bucko, it's all typical. Blimey! Sand and seal t' fins. Begad! Avast! Sand t' flashin' off t' nose cone. Avast! Fill t' spirals in t' tube. T' spirals actually aren't too bad, and t' tube is white. Aye aye! Blimey! 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. Begad! Seriously. Begad! Begad! Yeah, arrr, I could take some time t' make it look good, but this isn't one o' those rockets. Let's fly. Well, blow me down! Blimey! I want t' get started on me cert rocket. Avast, me proud beauty! Well, me bucko, blow me down! I'll take more time on that one.

Construction Rating: 4 out o' 5

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

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

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

Recovery:
Dad: My turn t' say it. Arrr! What he said. Blimey! We haven't flown either rocket yet as t' weather hasn't cooperated. My expectation is that, me hearties, like everythin' about this kit, matey, it will be typical Estes. Aye aye! Well, blow me down! T' chute is too big, and it will float, so we'll probably fly with a streamer or smaller chute. Arrr! As we get a chance t' fly these, shiver me timbers, ya bilge rat, I'll be postin' t' flight logs, and updatin' t' review through t' flight log comments. Arrr! Ahoy! 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, do I pass? When can I start on t' Matrix?
