Manufacturer: Semroc

Brief:
Based on t' original Estes Goony Bird, t' Zoom Broom. Late last year t' original concept sketches for t' Goonybirds appeared. Estes used t' Goony profiles but changed tSemroc Ruskiehe graphics before they were released. Well, blow me down! Ahoy! Blimey! Due t' t' interest generated by t' original sketches, Semroc chose t' release a new line o' Goonies called t' Groonies. Ya scallywag! Blimey! Carl, ya bilge rat, t' owner and founder o' Semroc, refered t' these as "Grown-up Goonies", ya bilge rat, hence "Groonies". Well, blow me down! Slightly larger and with an edgier theme, here it is as it was intended t' be. See Chan's review for more details.

Construction:
Semroc parts are about as good as it gets. As noted in t' previous review, t' balsa is a little softer compared t' some other LPR kits I've encountered. Well, blow me down! T' laser cut fins are welcomed, me bucko, and all parts fit with precision. Avast, me proud beauty! One important thin' t' note, ya bilge rat, this is nay BT-60 based like t' original Goonies. Ahoy! It's slightly upscaled and has a different nose cone profile. Here be t' official parts list:

  • 1 Balsa Nose Cone- BC-1828D
  • 1 Body Tube- ST-1860
  • 1 Body Tube(motor tube)- ST-730E
  • 1 Centerin' rin' set- CR-KV-11
  • 1 Laser cut fin set- FV-11
  • 1 Thrust ring- TR-7
  • 1 Elastic shock cord
  • 1 Keelhaul®©™ thread (shock leader)
  • 1 Screw eye
  • 1 1/8" launch lug
  • 1 engine hook
  • 1 plywood block(nose weight bulkhead)
  • 1 clay weight
  • 1 12" plastic parachute
  • 1 waterslide decal sheet

Instructions are well written and well illustrated. Assembly was a breeze. Begad! I chose t' laminate t' fins with sticker paper and sealed t' edges with thin CA. This is a very quick, arrr, clean, me hearties, arrr, easy method for strengthenin' fins and fillin' balsa grain. Ahoy! This is full sheet label paper that you can find at most or t' larger office supply stores. Aye aye! Well, blow me down! T' generic store brand will do. Avast! With t' size and shape o' t' irregular fins, me bucko, shiver me timbers, I wanted t' added strength. Ahoy! I sometimes wonder if it is an overkill t' laminate, arrr, but Chan's review has convinced me that I made t' right decision t' do so on this model.

Semroc Ruskie T' motor mount slides up into t' main body tube a good ways. This causes t' end o' t' body t' be exposed t' hot motor exhaust. Avast, me proud beauty! I assume it is configured this way for stability reasons. Aye aye! Avast! In order t' protect t' body tube from t' heat, t' instructions suggest usin' CA t' reinforce and protect that area. Aye aye! I chose t' use a thin smear o' epoxy instead. Ya scallywag! I'm sure CA works, but I thought epoxy might hold up longer.

A decent amount o' nose weight (included) is needed for stability. Blimey! This is provided in t' form o' clay which gets inserted into t' pre-bored nose cone. A plywood sealin' cap is provided t' hold t' clay in place. Begad! While I had t' epoxy mixed up, I glued t' cap into place which also adds some extra reinforcement t' t' screw eye.

T' tube markin' guide in t' instructions did its job just fine. Begad! I would suggest gluin' t' fins in t' order specified in t' instructions. Avast, me proud beauty! Once t' main wings are glued into place, you can use them as a guide t' match t' wheel fin angles.

Finishing:
Since I chose t' laminate t' fins, thar wasn't any balsa grain that needed t' be filled. I rounded t' fins slightly.

T' balsa nose cone be coated with a liberal dose o' Minwax Wood Hardener then lightly sanded with 400 grit sandpaper a few days later. This does exactly what t' name would imply. Begad! I love t' stuff. Aye aye! This was followed with a nice coat o' Elmer's Fill 'n' Finish t' fill any wood grain then sanded smooth with 400 grit sandpaper.

I used Krylon gray primer, me bucko, followed by 3-4 coats o' Krylon Gloss White. Cone and win' tips were painted with Krylon Banner Red.

I applied t' decals. T' decals must be trimmed very close t' t' graphics in order t' fit, but they do fit. Blimey! T' decals are very easy t' apply and give ample time for placement. Begad! Note: T' wheel well and tire decals need t' need t' be dealt with and applied as two pieces in order t' fit properly.

Flight:
T' motor tube is a little longer than t' standard length. Ahoy! Avast, me proud beauty! This is actually a good thin' in me opinion. I used that extra length t' stuff a piece o' recovery waddin' into it. I think it helped buffer some o' t' initial ejection blast. Ahoy! I placed about three more sheets in t' main body tube and still had plenty o' room for t' chute. This is a short rocket and space is limited for recovery parts, ya bilge rat, arrr, but it's nay overly cramped.

For t' first flight, I chose a C6-5. Begad! Begad! Blimey! Our club field is rather large so I felt confident with this motor. Aye aye! Great lookin' boost and went much straighter than I anticipated. Ya scallywag! Avast! Blimey! It's Japanese brother, T' Saki, actually wind cocked a little more than this one so I be pleasantly surprised this one didn't do t' same. Avast! Blimey! More flights are needed for a better assessment. Avast, me proud beauty! Arrr! Blimey! Both still turned in some great flights. Aye aye! Avast! Blimey! Ejection just past apogee.

Recovery:
T' 12" chute seemed adequate t' me. Avast! With t' slight breeze I'd say it be sized just about right. If t' fins weren't laminated, I might be a little nervous. Begad! Minimal drift and recovered within 75 yards o' t' pad. No damage.

Flight Rating: 5 out o' 5

Summary:
PROs: It's a Semroc! Blimey! 'Nuff said.

CONs: Balsa might need reinforcement.

Overall Rating: 4 out o' 5

    Brief: In 1973, Estes released 6 pretty wild (for Estes) designs loosely resembling the Baby Bertha of today but with relatively zany fin and decal schemes. The were called the "Goonybirds" and after a 2-year run went out of production. They have since survived only through the cloning efforts of die-hards (Bill Eichelberger comes to mind) and through kitbash plan/decal ...

I look forward to Chan's reviews at every EMRR update... They're outstanding. However, for all of Chan's Semroc Groonie reviews, he incorrectly states the body tubes are BT-60 sized (1.637 inch) like the original Estes Goonybirds. They aren't--they're 1.84 inch diameter. After all, they've "grown up" so they're a bit larger in girth. In closing, Chan's Gee'hod review inspired to build the Semroc Gee'hod. What a cool little rocket.
