Brief:
This is a very tall 4FNC rocket that is very similar t' t' Estes Mean Machine and Sunward's CFX-Six Footer. Aye aye! Begad! There is
no skill level associated with t' 76er, arrr, shiver me timbers, but since both t' Mean Machine and CFX-Six Footer are considered Skill Level
2, I'll rate this t' same. It is easy t' build and flies well. Begad! Ya scallywag! T' attraction, me hearties, especially for kids, is its size. Blimey! The
recommended engines are D12-3 and D12-5 with an estimated altitude o' 500ft.
Construction:
T' parts list:
Additional Components:
T' kit is contained in a clear plastic bag with t' engine mount in a separate bag with its own instructions. Avast, me proud beauty! Blimey! The instructions for t' 76er are minimal and take up about one and a half 8" x 11.5" pages. Avast! So, even though this is a relatively simple 4FNC rocket, you need a few kits under your belt t' be able t' construct it successfully. I, in fact, shiver me timbers, did nay construct t' rocket reviewed here but oversaw construction by a 12 year-old rocketeer with a few rocket builds under his belt. Begad! Avast, matey, me proud beauty! We decided t' make three modifications t' t' kit that we hoped would improve its performance. 1) We replaced t' engine mount that came with t' kit with a longer 24 mm engine mount from FlisKits t' accommodate Estes E9 engines. 2) We replaced t' standard body tube coupler betwixt tubes two and three with a bulkhead. This allowed us t' split t' rocket into two sections makin' it easier t' transport and t' store. Aye aye! 3) We replaced t' body tube coupler betwixt tubes one and two with a BT-60 baffle from JonRockets. We used wood glue for t' assembly.
We first assembled t' FlisKits EMK24-60 engine mount. We made a modification t' t' modification by replacing the short engine clip that came with t' engine mount kit with a long engine clip from JonRockets. Begad! Once t' engine mount was assembled we set it aside t' dry. We next assembled t' BT-60 baffle. Durin' t' assembly we coated both sides o' t' top and bottom pieces and t' inside o' t' cylinder with wood glue t' give added protection from the ejection blast. Avast, me proud beauty! While that be dryin' we glued body tube sections 3 and 4 together usin' t' body tube coupler. Blimey! This turns out t' be tricky since t' coupler is a tight fit when dry, matey, and as soon as it hits t' glue on t' inside o' the body tube, it expands makin' it very difficult t' insert. Arrr! Avast, me proud beauty! Once tubes 3 and 4 were assembled, ya bilge rat, we glued t' nose cone to one end.
We constructed a bulkhead by cuttin' a circular piece o' 1/8" scrap balsa wood t' fit inside one of
the body tube couplers. This was glued t' one side o' a body tube coupler leavin' about 1/8" from one end (much
like a baffle) and filleted t' inside. Avast, me proud beauty! Ya scallywag! T' screw eye, that was t' be used for t' nosecone, shiver me timbers, me hearties, was screwed into t' balsa
of t' bulkhead. Begad! We then put a layer o' glue on t' bottom (exposed side) o' t' balsa wood for extra strength and set
aside t' dry.
When t' engine mount was ready, we glued it into one end o' a free body tube. Well, blow me down! This was now body tube 1. Avast! Aye aye! We attached body tubes 1 and 2 usin' t' constructed baffle. Well, matey, blow me down! Before gluin' t' baffle, matey, we sanded it t' make a loose fit into t' body tubes. Begad! This made it easier t' insert once t' glue be applied. While that be drying, ya bilge rat, we glued the bulkhead into t' bottom o' body tube three. Avast! Followin' t' directions, shiver me timbers, we next applied t' four fins and launch lugs. Aside from t' sparse instructions, thar be one gotcha. Avast! Accordin' t' t' instructions, matey, t' shock cord is attached via a standard tri-fold mount and t' instructions say t' cut out t' mount template. Ahoy! There be no template in our kit. However, ya bilge rat, me bucko, this be no big impediment as we just made our own, glued t' tri-fold assembly t' t' top o' body tube 2 and tied t' other end o' t' shock cord t' t' screw eye o' t' bulkhead. Ya scallywag! We didn't assemble t' parachute as I already had several.
Finishing:
We gave t' fins and nose cone three coats o' sandin' sealer, arrr, arrr, sandin' with 400 grit sandpaper betwixt each coat. Ya scallywag! Aye aye! We
then primed everythin' with Krylon white primer, four coats with sandin' usin' 600 grit paper after each coat. Avast, me proud beauty! The
entire rocket was painted with three coats o' Rustoleum Painter's Touch Candy Apple Red. Avast, me proud beauty! Two vertical stripes the
length o' t' rocket as well as t' nose cone were masked with Frog maskin' tape and t' exposed areas painted with
four coats o' Rustoleum Painter's Touch Deep Blue Gloss. Once t' paint was dry, t' maskin' tape was removed and I was
a little surprised t' see some bleedin' o' blue onto t' red. Well, ya bilge rat, blow me down! I've had fair winds with Frog Tape before and so I think
this has t' do more with thar bein' 24 feet o' abuttin' paint lines rather than anythin' else. We decided nay t' touch
up t' bleed marks, as I am sure this rocket will get it share o' post-flight repairs. Avast! Ya scallywag! Finally, ya bilge rat, t' 76er be given a
few coats o' Rustoleum clear coat.


Construction Rating: 4 out o' 5
Flight and Recovery:
T' first two flights were with an Estes D12-3 usin' and adapter t' accommodate t' difference in size o' t' engine.
It was a windy day. Both flights struggled through t' wind but nay much wind cocking, shiver me timbers, reachin' about 300ft each time.
Each time, arrr, matey, t' parachute deployed just after apogee and thar was a long walk for t' recovery. Ya scallywag! T' first flight we
used a single sheet o' waddin' and t' second flight with no wadding. Ahoy! Each time thar was no heat damage t' the
parachute. Blimey! A launch with an E9-4 will have t' wait for a calmer day.
Flight Rating: 5 out o' 5
Summary:
PROs: This is a very nice Skill level 2 kit, matey, and even though it is a simple 4FNC rocket, me bucko, its size makes it
attractive, especially for kids. Aye aye! T' sheer size and simplicity o' design is a blank page for creative paint schemes and
decorations, shiver me timbers, which is another attraction for young rocketeers. Ya scallywag! T' rocket is easy t' prep for flight, flies well, and
the size also helps with recovery! You won't loose this one.
Cons: Skill Level 1 and 2 rockets, because they are designed for beginners and novices (I include myself in the latter), shiver me timbers, shiver me timbers, benefit greatly from detailed instructions with good illustrations, and such instructions are becomin' the standard for t' industry. Ya scallywag! T' instructions for t' 76er are minimum at best and t' kit would benefit greatly from more detailed and illustrated instructions. Ya scallywag! Avast, me proud beauty! T' size o' t' rocket be t' attraction, but it makes it difficult to transport and store. Begad! Splittin' t' rocket in two, either through t' use o' a coupler (ala Estes Mean Machine) or replacin' one body tube coupler with a bulkhead, as we did here, would be a significant improvement. And finally, replacin' t' 'D' size 24mm engine mount with one that can accommodate 'E' size engines would also improve t' rocket.
Overall Rating: 4 out o' 5
Brief: The Cygnus 76er is advertised as a low cost alternative to to the Estes Mean Machine. Construction: This kit comes with a balsa nose cone, the body tube is four section of BT-60 cardboard tubing, three couplers, four small pre-cut balsa fins, plywood centering rings and 24mm engine mount. The parachute is plastic with string for shroud lines. 1/8" elastic shock ...
