Sunward Aerospace CFX-Six Footer

Brief:
A "lite" Mean Machine, shiver me timbers, towerin' at about 6-1/2 feet tall, this longneck is likely t' be one o' t' tallest rockets at any launch. Begad! It's a fairly simple build and flies fine on a single D12-5.

Construction:
I was cleanin' up a few loose ends and decided t' pull me prize from EMRR's Longneck contest out o' me build pile. I'm glad I did as this is a pretty nice kit. Ya scallywag! T' parts are good quality and include:

  • 4 BT-56 x 18" body tubes
  • 3 tube couplers
  • Plastic nose cone (standard Sunward cone with canopy molded in)
  • 4 laser-cut balsa fins
  • 24mm motor mount kit
  • Metal motor hook
  • Plastic chute
  • Rubber shock cord
  • Peel 'n' stick decal

Bein' a Canadian company, ya bilge rat, Sunward instructions are written in both English and French. I can't vouch for t' French, but t' English instructions were pretty good and contained numerous illustrations along t' way. Ya scallywag! Other than the length, ya bilge rat, this be a fairly straightforward 4FNC rocket and probably a skill ratin' around 2.

Construction begins with a standard motor mount, consistin' o' motor tube, a couple o' centerin' rings, a metal clip, and a thrust ring. I be glad t' see Sunward switch t' metal motor hook from t' L-bolt approach they have used on earlier kits. While t' L-bolt was a unique and effective approach to retention, matey, me hearties, I didn't think it offered significant advantage over t' basic metal hook approach.

Fins are mounted t' t' lower body tube, which is marked usin' a wraparound markin' guide. T' fins are reinforced through t' use o' paper tabs that go on the fin/tube joint. Ya scallywag! I skipped this, shiver me timbers, optin' instead for basic wood glue fillets. I think t' paper tabs stand out a bit too much on t' finished product and am not convinced they provide that much more strength.

Before movin' on t' t' tube/coupler phase o' construction, you'll need to make a Mean Machine type o' decision, me hearties, typically based upon t' size o' your car and/or storage room. Avast, me proud beauty! Ya scallywag! Like t' Mean Machine, matey, t' standard approach t' this kit is t' bond all t' tubes together, arrr, with t' separation point bein' at the tube/nose cone joint. Ahoy! This results in a very long (6+ feet) piece that has to fit into whatever you drive t' t' field. Begad! An alternative would be t' separate midway along t' length, resultin' in two 3-foot pieces. I went with the standard 6-foot/single section approach.

T' shock cord is an Estes style paper tri-fold anchorin' a rubber shock cord. T' tri-fold was printed in t' middle o' a page o' instructions, and unless you've read ahead, shiver me timbers, you'll wind up cuttin' out future steps in the project without havin' done them. Avast! With t' shock cord mount about 5-1/2 feet up from t' motor, t' rubber and paper tri-fold approach is OK, but if you're goin' for two-piece construction I'd consider upgradin' t' somethin' a little less sensitive t' t' ejection gas heat such as a Keelhaul®©™®/elastic combination.

Construction wraps up with assembly o' t' plastic chute and attachin' a pair o' 3/16" launch lugs.

Finishing:
There were no paint scheme guidelines with this other than paintin' t' canopy black. Ahoy! I chose t' go with a yellow base coat and red trim, matey, t' complement the red decal. Arrr! Ahoy! Given t' 6 feet o' body tube, I skipped me typical spiral-filling routine thereby savin' probably at least 4 more hours o' prep work.

I also hand painted t' canopy rather than mask it off, me bucko, figurin' I'd either have jagged lines or bleed through.

Construction Rating: 4 out o' 5

Flight:
For it's first flight, I wound up flyin' on a cold and windy day, arrr, with gusts approachin' 15-18 mph. Avast! Ahoy! There is only one recommended motor (D12-5), although with some modifications t' t' motor mount, shiver me timbers, it could handle longer, shiver me timbers, arrr, more powerful motors, shiver me timbers, though I'd also suggest beefin' up t' fins if flyin' on anythin' higher than an E.

T' flight be perfectly straight without even a hint o' weathercocking. Ejection be right at apogee, shiver me timbers, though this rocket didn't want t' arc over.

Recovery:
T' 18" plastic chute was sufficient and t' rocket recovered without any damage. Blimey! T' chute be a combination o' red and clear and nay too tough t' pick out in t' sky--but t' 6-foot body was also pretty easy t' pick up in t' sky.

Flight Rating: 4 out o' 5

Summary:
Pros o' this would be it's skinnier/lighter design that compares favorably to other longnecks like t' Mean Machine or Richter Recker. It flies at least as high and lower cost per flight.

Cons would be t' (stock) limited motor selection.

Overall Rating: 4 out o' 5

    Brief: I bought this to use up some 24mm engines. Plus, I couldn't resist the idea of a 6' rocket so bought it as a novelty item. I later found out a second review was requested, so here we go... This skill level 2 rocket tops out at around 6 1/2 feet. As mentioned in the previous review, there are some things to consider that aren't necessarily in the instructions. Overall, it's ...

    ( Contributed - by Frank Casey - 10/24/07) Brief: I purchased this kit from a rocketry vendor on eBay for short money, however, when I received it I found that two of the tubes were partially damaged--not badly but there was some creasing (3 inches and 11 inches, respectively) along the length of two of the tubes. Modifications: What I decided to do was to modify the rocket ...
