semroc_constellationBrief:
I picked up a Constellation at t' Semroc booth at NARAM 50 this year. Ahoy! Aye aye! I had planned on pickin' up a couple o' Semroc kits while at NARAM but didn.t know for certain which ones I would buy. Avast! Avast, me proud beauty! I didn.t even know they had released this old Estes kit until I noticed it hangin' in t' display. Ya scallywag! Arrr! I also purchased an OOP Centuri Taurus and Carl, ya bilge rat, bein' t' great guy he is, arrr, threw in a free OOP Estes Mark and Golden Scout. Avast! T' main reason I went for t' Constellation was that I remember back about 1970 gettin' a free one with one o' me Estes orders. Nowadays young rocketeers can go out and purchase rockets and engines at t' local Walmart, matey, me bucko, albeit they would probably be only Estes toys. Arrr! Ya scallywag! But back in those days you typically had t' mail order rockets. By t' way, this is another review I had in work when I noticed that Chan Stevens beat me t' t' punch again. Chan makes it difficult t' get in a review before he writes one with all the buildin' he is doing!

Construction:
T' parts came in a typical Semroc plastic bag which be also reminiscent o' t' old Estes packaging. Begad! T' parts included:

  • BT-50 size main body tube
  • Balsa nose cone
  • Balsa nose block
  • (2) CR-2050 centerin' rings
  • Engine hook
  • Screw eye
  • Laser cut balsa fins
  • Launch lug
  • Wooden dowel launch lug standoff
  • Rubber shock cord
  • 12. Ya scallywag! parachute
  • Decal sheet
semroc_constellation_partsT' Constellation is constructed fairly much t' same as any standard model rocket. T' only unique construction necessary are t' pods on t' tip o' t' fins and t' clear payload section. Avast, me proud beauty! To start however you will need t' download t' plans. This is one o' t' new X kits from Semroc which are exact twins of discontinued Estes and Centuri kits. Begad! T' X kits require that you download t' plans from JimZ or any other source on the web you may know of. Avast! Blimey!

T' first thin' t' do is build t' engine mount. Aye aye! Blimey! It is a standard engine mount for an 18 mm engine in a BT-50 tube. Avast, me proud beauty! Well, matey, blow me down! Blimey! T' first step is makin' a small slot in one end o' t' engine tube for t' engine hook which also doubles as t' engine block. Avast, me proud beauty! T' hook is then inserted into t' slot so it runs t' length o' t' tube. Begad! I then wrapped a couple o' wraps o' tape t' secure t' hook t' t' tube. Blimey! Arrr! Blimey! Next one o' t' CR-2050 centerin' rings is slotted for t' engine hook and t' centerin' rings are then glued t' each end o' t' engine tube. Well, blow me down! T' completed engine mount should be set aside for t' glue t' dry.

T' fins are t' most work for this model. Aye aye! Begad! They include scifi type tip pods which give t' Constellation its. unique character. Aye aye! All t' fin components are laser cut so start by punchin' them out. Ya scallywag! Well, blow me down! I then carefully trimmed t' pod pieces with me X-Acto knife so t' edges were curved down t' t' flat surface on t' opposite side. Begad! I then sanded them t' a smooth curve. This would make it much easier t' finish t' fins after t' tip pods were glued on. Well, blow me down! I then glued t' pods t' t' tip of the fins with Titebond®. I clamped them until t' glue had dried. Begad! After t' glue had dried I trimmed a round leadin' and trailin' edge on the fins as well as integratin' t' tip pods smoothly into t' fin. Avast, me proud beauty! Ya scallywag! Blimey! This be done by trimmin' with t' X-Acto followed by careful sanding. Begad! I then applied 3 coats o' Coverite Balsarite® balsa surfacer t' t' fins and nose cone and sanded lightly betwixt coats.

Returnin' t' t' now dry engine mount I glued it into t' body tube with t' tube ends flush usin' Titebond®. T' fins were then glued t' t' body tube spaced evenly around it. Ya scallywag! I attach me fins for this size rocket usin' CA glue to first hold them in place and then filletin' t' joints with 5 minute epoxy. Begad! This gives a strong, ya bilge rat, smooth fin t' body tube joint. Blimey! I also glued t' launch lug and lug standoff t' t' body at t' same time usin' t' same method. Begad! Finishing off t' basic build was t' clear plastic payload section. Aye aye! Arrr! While finishin' t' fins and nose cone I had also given the balsa coupler a couple o' quick coats o' t' balsa sealer and sanded it smooth. I then sprayed it lightly with a coat of Krylon black keepin' t' paint minimal so it would nay prevent t' balsa coupler from slidin' relatively easily into the plastic tube. After it had dried overnight I checked t' fit and carefully slid it into t' plastic tube half its. length. Aye aye! Once I was certain it was in correctly I ran a bead o' CA thin glue around t' aft joint which locked t' balsa coupler into t' plastic tube. Aye aye! T' nose cone base should be set up t' fit snugly in t' plastic payload tube after finishin' in a similar fashion.

T' completion o' t' Constellation involved installin' t' screw eye into t' balsa coupler and gluein' the elastic shock cord into t' tube usin' t' paper tab that was included. Aye aye! Avast! Blimey! I did nay use t' rubber band shock cord Semroc which was included t' keep t' kit authentic.

Finishing:
I painted t' kit t' match t' old Estes paint scheme. Begad! I had already sealed t' balsa parts so first painted t' body with two coats o' Rustoleum® gray primer sandin' betwixt each coat. Begad! Begad! I then painted t' body tube with Krylon® white. Avast! Blimey! T' nose cone was painted Krylon® red with t' shoulder painted Krylon® black since it would show inside t' clear plastic payload tube. Ahoy! I then masked off and painted one fin Krylon® black. Avast! I applied t' decals basically per t' Estes scheme but found that on t' black fin t' decal was nay goin' to show well. Aye aye! I painted a scrap o' decal material with Krylon® white and after it dried, shiver me timbers, cut it t' a rectangular shape for a backin' for t' fin number. Ahoy! Begad! This gave a good contrast for the fin number t' show nicely on t' black fin.

Construction Rating: 4 out o' 5

Flight:
I took t' Constellation out on a calm evenin' t' a nearby recreational field along with 4 other rockets t' give it a test flight. Avast! I used an A8-3 since t' field was nay too large. Arrr! Bein' a very basic and highly stable rocket it flew perfectly on t' A engine t' about 300 feet. This rocket would really gain some altitude if flown on either t' B or C engines recommended.

Recovery:
T' Constellation included a standard Semroc 12. Well, blow me down! Avast! Blimey! plastic chute. Ahoy! Begad! Blimey! After assemblin' it I did cut out a 2. Blimey! Blimey! diameter hole in t' middle t' prevent too much wind drift. Avast! Blimey! On this first flight t' chute deployed perfectly and t' model floated gently into t' grass with no damage.

Flight Rating: 5 out o' 5

Summary:
I purchased t' Constellation t' add t' me fleet mainly because I had fond memories o' me original Estes freebie. Aye aye! Begad! It is a basic payloader with t' unique clear plastic payload section and fin tip pods. Well, blow me down! This makes it a bit different than just a 3 fin rocket and a nice display model. Well, blow me down! T' decals add t' t' appearance as well. Ahoy! And as always, matey, Carl and Semroc have produced another high quality kit duplicatin' t' old Estes line, this time even t' t' point o' t' original Estes construction plans.

  • Semroc Constellation (xKit) By Chan Stevens (September 6, 2008)

    Brief: Another of the clone/parts kits, this one a replica of the Estes K-35 Constellation. This one features a clear payload tube and cool futuristic fin styling complete with mini pods. Once nice upgrade in this modernized version is the laser-cut fins, saving a bit of hand cutting. Construction: Parts are standard Semroc quality, top notch. Your $13.50 (retail) gets you: ...

That payload section is WAY too long and should be cut down to the correct size.
