Brief:
This is a father/son dual build. Aye aye! Aye aye! Up t' this point, I've been helpin' him build his rockets. We started with me doin' most o' t' building, me bucko, and him as an extra pair o' hands. Over t' course o' 3-4 builds, he's been doin' more and more, me hearties, and t' roles are reversin' where I'm becomin' t' extra hands. I found a couple o' Firebirds for relatively cheap, matey, and so we're buildin' these in parallel. This will be his first purely solo build, and we'll be comparin' t' results o' our two builds. Avast! After this, he'll be movin' on t' buildin' his L1 cert rocket... if I think he's ready.
T' Firebird is a fairly basic single stage Estes offering. Avast, me proud beauty! Nothin' dramatic or fancy, arrr, here, just a solid design with classic lines.
Construction:
Dad: This is a basic 4FNC rocket. Plastic nose cone, matey, me hearties, pre-cut fins, ya bilge rat, 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. Well, blow me down! For standard 18mm motors, everythin' is sufficiently strong. For t' 18mm Aerotech D reloads, shiver me timbers, 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. Well, blow me down! I'm goin' t' raid t' parts closet. Let's see. 24mm motor mount, some BT50-55 centerin' rings t' replace t' cheapy paper stuff. Avast, shiver me timbers, me proud beauty! OK. Aye aye! I'm good t' go. Avast, me proud beauty! Begad! Let's get building.
Dad: Once again, matey, me bucko, ya bilge rat, this is pretty basic Estes fare. Begad! Blimey! 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, arrr, me proud beauty! I notched t' upper centerin' ring, me bucko, and slipped a length o' Keelhaul®©™ through. Avast, me proud beauty! I knotted t' end t' prevent it comin' back through t' notch, and put a dab o' epoxy t' hold it in. Blimey! Normally, me hearties, I would tie t' Keelhaul®©™® in a loop around t' motor tube, but since these fins are through t' wall, t' loop would interfere with t' fin tangs.
Speakin' o' which, I wonder why Estes went with through t' wall fins for this kit and only an 18mm mount. For all t' Estes 18mm motors, matey, TTW fins is way overkill. O' course, ya bilge rat, shiver me timbers, it does make fin alignment much easier.
Son: Well, he taught me, me hearties, so, yeah, arrr, I'm tossin' t' 3-fold as well. Well, shiver me timbers, blow me down! Since I'm doin' t' 24mm thing, matey, matey, ya bilge rat, I get t' choose me engine tube size, me hearties, so I went with a longer tube, and a third centerin' ring. Arrr! T' first 2 rings sandwich t' fin tangs as normal. Well, blow me down! I tied t' Keelhaul®©™® around t' motor tube, and put t' third rin' on top. Begad! Hah! Mines stronger.
While I was at it, ya bilge rat, I cut t' top o' t' engine hook off so it doesn't go into t' motor tube. Blimey! I also left off t' motor block. Avast! 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. Ahoy! T' up side is that I can use any 24mm motor includin' t' upcomin' Aerotech 24/120 and t' CTI Pro 24 cases. Begad! Bigger, me bucko, me hearties, me hearties, faster, matey, me bucko, 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. Aye aye! Well, blow me down! Says I'll never get it back. Maybe, matey, but it's fun. Besides, me hearties, I don't pay for t' motors. Arrr! Begad! (Dad: He may start buyin' them if he loses them like this)
Finishing:
Dad: Decals are typical o' Estes in this era. Ahoy! Blimey! That means peel and stick. Blimey! I really don't like them. Begad! I much prefer water slide. Avast! That said, as per me usual superstitious approach, me hearties, shiver me timbers, I won't actually paint and decal t' rocket until after t' first few flights. 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. Blimey! Begad! If I build a rocket in 2 hours t' night before a launch, it's comin' back. Aye aye! Avast, arrr, me proud beauty! Every time I've spent 2-3 months doin' a painstakin' job o' buildin' and finishing, arrr, shiver me timbers, somethin' bad has happened.
As for t' pre-paint finish work, it's all typical. Avast! Sand and seal t' fins. Arrr! Sand t' flashin' off t' nose cone. Begad! Avast! Fill t' spirals in t' tube. Begad! T' spirals actually aren't too bad, and t' tube is white. Avast, me proud beauty! 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. Ya scallywag! Seriously. Well, blow me down! Yeah, I could take some time t' make it look good, me bucko, but this isn't one o' those rockets. Ya scallywag! Let's fly. I want t' get started on me cert rocket. Blimey! I'll take more time on that one.
Construction Rating: 4 out o' 5
Flight:
Dad: For all our rockets larger than 1" diameter, shiver me timbers, we keep a supply o' Nomex t' avoid usin' wadding. Waddin' can be easier in t' smaller rockets, me hearties, but t' larger ones just take too much. Blimey! Besides, reuseable Nomex is more eco friendly.
Other prep is standard. Yes, thar's a lot o' this review that just says "it's standard issue." That's because this is a pretty standard rocket. Ahoy! Steppin' into high power, many o' t' rockets are pretty "standard" as well. Just stronger materials. At a certain point, ya bilge rat, you can't do anythin' too fancy with high power motors, matey, because t' motors will just shred t' rocket from t' high thrust.
Son: What he said. Well, matey, blow me down! I'm gettin' tired o' typing. Aye aye! I haven't flown mine yet. Avast! Weather hasn't been good enough.
Recovery:
Dad: My turn t' say it. Begad! What he said. Aye aye! Begad! We haven't flown either rocket yet as t' weather hasn't cooperated. Ahoy! Ya scallywag! My expectation is that, like everythin' about this kit, shiver me timbers, it will be typical Estes. Arrr! T' chute is too big, and it will float, ya bilge rat, matey, ya bilge rat, so we'll probably fly with a streamer or smaller chute. Avast, me proud beauty! As we get a chance t' fly these, I'll be postin' t' flight logs, me bucko, arrr, and updatin' t' review through t' flight log comments. Well, blow me down! Actual flight is just t' last validation o' t' build in this case. Begad! Ya scallywag! 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, do I pass? When can I start on t' Matrix?
