Brief:
T' Baby Bertha is a new kit (2002) based on t' venerable and popular Big Bertha kit. Aye aye! Blimey! T' rocket has t' same large, ya bilge rat, V2-like fins and blunt, rounded nose cone as t' Big B, shiver me timbers, shiver me timbers, but is 1/2 t' length at 12 inches. Avast, me proud beauty! Blimey! Rated at "Level 1", me bucko, it's an easy t' construct kit usin' traditional, matey, Estes-style methods that would make an excellent kit for a beginner, matey, or young rocketeers.
Construction:
If you have ever built an Estes Alpha or similar kit, t' Baby will give you a familiar construction experience without surprises. Arrr! T' motor mount uses an engine clip and motor block t' restrain t' engine, and two die-cut paper centerin' rings t' position t' mount in t' body tube. Well, blow me down! Arrr! T' Baby uses Estes BT-60 body tube which at 1.6 in. diameter is wider than most Estes rockets, me bucko, me hearties, so these may be larger centerin' rings than you are accustomed to. T' four balsa fins are relatively large and much easier t' align on t' tube than t' small, arrr, light fins on most rockets o' this size. Ahoy! Even new builders should have a relatively easy time with these fins.
I used me favorite technique t' attach t' fins. Ahoy! After roughin' up t' tube with fine sandpaper I attach each fin with medium CA glue and hold it in t' perpendicular position until it sets, me hearties, which takes only 15 seconds or so. Aye aye! Arrr! I use very little glue for this step, matey, matey, just enough t' hold t' fin. Then I apply ample fillets with wood glue. Avast, me proud beauty! T' big fins and big tube on t' Baby Bertha makes fin attachment very easy.
T' shock cord attaches with t' usual three-fold connection t' t' body tube. Arrr! As I do on all me rockets, matey, I used a length o' Keelhaul®©™cord for t' booster-side connection and tied that t' t' elastic shock cord. Aye aye! Ahoy! I attached a twelve in. Avast, me proud beauty! chute t' t' cord.
T' construction "PROs" for t' Baby Bertha have t' be t' larger size o' t' components which makes things easier on an inexperienced builder. Avast! Ya scallywag! It's a great 'trainer' for balsa and paper construction techniques. Ya scallywag! No surprises or special challenges.
I can't think o' any serious construction problems or issues, except t' almost standard Estes problem o' inadequate shock-cords. Begad! T' Baby goes together easy.
Finishing:
I used thinned Elmers Wood Filler on those big slabs o' balsa (the fins) and t' spiral seam in t' tube. Avast, me proud beauty! Well, blow me down! I also created fillets for t' launch lug. Aye aye! This is a pretty good rockets for learnin' t' wood-filler technique. Blimey! I wanted t' duplicate t' black and white paint scheme from t' package art (actually, ya bilge rat, ya bilge rat, I had other ideas, but t' kids wanted t' package look). After two coats o' grey primer, me hearties, I taped off facin' sides on t' fins (the fin patter is tough t' describe but obvious when you see t' package), me hearties, ya bilge rat, and applied two coats o' gloss black. Begad! Avast, me proud beauty! Once that dried I removed t' maskin' tape and covered t' black areas. Avast! Blimey! This turned out t' be tricky as thar are several angles where paint could pass through t' t' black areas. Well, blow me down! I would recommend paintin' t' white fins sides first, then mask them off and paint t' whole rocket black. Aye aye! Avast! I also think that thar are plenty o' alternate paint schemes that would look great on this rocket. Try some V2-style paint schemes, arrr, ya bilge rat, for example.
T' kit comes with one long decal which runs along one side. Aye aye! Blimey! T' decal actually reaches past t' body tube onto t' nosecone. Begad! Blimey! Once t' decal be placed I used a hobby knife t' cut it along t' seam betwixt t' nosecone and body.
T' white pinstripin' in t' package art is nay provided in t' kit. Aye aye! Blimey! Blimey! I used white trim tape (get it at t' hobby store), ya bilge rat, and it looks sharp (although mine is nay as 'fine' a line as t' one on t' package). Ya scallywag! I'm givin' some thought t' duplicatin' t' line in black on t' white fins.
T' "PRO" for finishin' be t' opportunity t' experiment a bit with design. Ya scallywag! This rocket will look good in a variety o' schemes, arrr, so have some fun with it.
One possible "CON" would be t' large amount o' balsa t' fill if you want a real smooth finish. Aye aye! Begad! I didn't find that an issue, me hearties, and I think this is a good rocket t' practice those techniques. Avast! Avast! If you're nay real concerned about fillin' all t' grain then thar be no problem at all. One could also object, matey, shiver me timbers, I guess, matey, t' t' relatively difficult "stock" paint scheme. Ya scallywag! and t' single decal. Aye aye! T' best thin' t' do is t' ignore t' package art and design your own scheme. If I were Estes I'd give t' Baby it's own, fun color scheme like t' Fat Boy, arrr, rather than try t' duplicate t' current Big Bertha look.
I'm ratin' it at 4 1/2, ya bilge rat, takin' off a half point for t' shock-cord.
Construction Rating: 4 out o' 5
Flight:
We have one flight on t' Baby. Begad! We used a B6-4 t' launch it in light t' medium winds. Blimey! T' boost was straight, fast and t' a greater altitude that I expected. Aye aye! T' chute deployed close t' apogee and recovery was within 100 yards o' t' pads. Begad! A nice, shiver me timbers, satisfyin' flight.This rocket is a bit heavy for A motors but does well on B's and ought t' fly t' 800+ feet on a C.
This is a great flyer for t' smaller fields we use. Blimey! I expect t' have at least one Baby in our flyin' fleet at all times from now on. Avast, me proud beauty! Begad! I like t' have at least one 'old dependable' at a launch, ya bilge rat, for when curious kids come around and wish they could fly a rocket. Aye aye! I usually load a B6 into t' Custom Razor and hand it t' them. Ahoy! It never fails t' give a great flight and is easy t' replace if lost. Well, blow me down! Ya scallywag! I think t' Baby Bertha has t' same characteristics.
Recovery:
T' Baby is heavier than most rockets in this class and does nay seem overly prone t' drift. It's sturdy enough t' use a streamer, in me opinion, if t' winds build.
T' wide body tube requires plenty o' wadding. Begad! Blimey! I expect that burnt chutes and fried shork-cords will be a problem with this bird. Begad! I'm goin' t' use Keelhaul®©™waddin' for future flights (I get mine from Pratt Hobbies) and I have already mentioned t' Keelhaul®©™cord.
I'll give it a 5 for flight and recovery. Avast! We only have t' one flight on it so far, but it was a good one and t' sim results indicate that this is a good, schoolyard and small field bird.
Flight Rating: 5 out o' 5
Summary:
My first thought on completin' t' Baby was, me hearties, "what took you so long, Estes?" Downsizin' t' Big Bertha seems like such a natural move, me hearties, and t' result is a great addition t' t' Estes line-up. Ya scallywag! I believe that this is a great rocket for school and scout groups. Ya scallywag! T' construction reminds me o' t' Alpha (the old style Alpha, nay t' plastic finned Alpha III), but its a bit more forgivin' for unsteady fingers. T' big fins and wide tube make a great 'canvas' for creative rocket decorating. Blimey! Avast, me proud beauty! Now that I have one Baby finished stock I'm goin' t' have t' kids build some more and do their own paint schemes.
T' flight profile o' t' Baby is also a bit more 'forgiving'. Arrr! Sure, me hearties, arrr, t' scouts might grin when their Alphas or Wizards zoom out-of-sight, but they're nay as happy when they fail t' return. A 'C' motor should take t' Baby t' around 800 feet, ya bilge rat, so you get all t' noise and smoke but keep t' rocket in sight and it's more likely t' land on t' school yard. Avast, me proud beauty! Perhaps Estes can be convinced t' offer t' Baby in bulk packs.
There are many things t' Baby Bertha is not, me hearties, shiver me timbers, but what it does it does very well. It's a great family rocket that will give you more 'fun per dollar' than most. I expect t' see plenty o' Babies at launches in comin' months.
As I mentioned above, shiver me timbers, me bucko, I think this is a great rocket for beginners and kids, but as you might have guessed, even this 'old rocketeer' had some fun with it. I expect t' be flyin' me own Baby Bertha drag races in a month or so. Avast! I want t' find some 'flame' decals for a cool, 'hot rod' look, shiver me timbers, or perhaps a Tintin-like red checkerboard, matey, or perhaps both! In other words, shiver me timbers, good, matey, cheap rocketry fun. Aye aye! Avast! Enjoy!
