Brief:
This is a nice entry level mid/high power kit. Begad! Blimey! Ahoy! Blimey! Large tube, me bucko, lots o' room for recovery gear, simple build, arrr, matey, and a great
flier.
Construction:
T' main components consist o' high quality parts and is a very complete kit!
Although this be t' type o' kit I normally do nay purchase, shiver me timbers, I was t' lucky winner o' it at a local rocket meet as a door prize. Avast! Blimey! Blimey! Blimey! However, me hearties, after openin' t' kit and inspectin' t' parts, matey, I realized that it be a very complete and well thought out package. Begad! Blimey! T' only items nay included were attachment links for t' shock cord and some kind of positive motor retention. Since motor retention is a personal matter and t' links would only add unnecessary weight to the kit, shiver me timbers, this be nay a problem for me as I have plenty o' both items on hand. If you are goin' t' be buildin' a few larger rockets, shiver me timbers, shiver me timbers, it would be a good idea t' stock up on these items.
T' instructions were easy t' follow with many good pictures o' t' build and pictures tell
a better story o' what t' do. Ya scallywag! Ahoy! This is a great kit for t' Level 1 attempt and could also be used with t' larger L2
motors with proper balancing. Avast, me proud beauty! Avast, me proud beauty!
It is solid as a tank without t' excess weight and when built right, it will be around for many, arrr, ya bilge rat, many flights. Begad! Begad!
Construction starts with t' motor mount and is as simple as can be. Well, blow me down! Blimey! Ya scallywag! Blimey! However, me bucko, see below for t' extra steps that I do t' make it very strong. After addin' two T-nuts t' one rin' for motor retention, me hearties, rough up t' motor tube with 60 grit sandpaper for better glue adhesion and mark t' tube for t' rings. Blimey! Blimey! Two centerin' rings on opposite sides o' the motor tube, ya bilge rat, me hearties, a little epoxy and that's it. Well, blow me down! Blimey! Add t' shock cord eyelet as instructed and t' motor mount is finished. Ahoy! Blimey! Ya scallywag! Blimey! The only addition I did here be t' use a closed eyelet. Avast! Blimey! Avast, me proud beauty! Blimey! I have a bunch that were welded closed for me and they are better to keep all t' recovery gear on t' rocket. Begad! Blimey! Although t' bent eyelet seems t' be quite strong, ya bilge rat, they have been known to open up.
Since t' body tube be nice and large, arrr, I did nay attach t' shock cord t' t' eyelet before gluin' t' motor mount into t' body tube. After a test fit I could easily get me hand inside t' attach a quick link with t' cord. While t' mount be test fitted inside, I marked t' location o' t' upper ring, pulled t' whole thin' out and added epoxy t' t' proper locations and slid t' assembly back into its finished position. Arrr! I made sure t' fin slots were clear o' t' CRs. I usually like me fins t' butt up t' t' centerin' rings for added strength and was thinkin' of addin' a third rin' t' do this, ya bilge rat, but I decided t' just build this one as t' kit calls for. I wasn't plannin' on ripping this one with large motors so stock was goin' t' work fine.
As t' pictures show, I do me centerin' rings a little differently! I only glued t' upper rin' t' t' motor tube at first. Once that has set up, ya bilge rat, I screw two bolts into t' T-nuts, place epoxy at t' upper rin' mark in t' tube, slide t' lower CR onto t' motor tube WITHOUT GLUE and slide t' assembly into t' body tube. Ahoy! Well, blow me down! This way t' motor tube is properly centered in t' body and when t' upper rin' has set up, t' lower rin' can be removed. You now have access to t' bottom o' t' upper rin' and can add internal fillets t' t' fins and upper CR. T' internal fillets add very little weight and an immense amount o' strength!
For all t' internal joints and fillets, I used 30 minute epoxy and t' outside fillets were done with Titebond II. Well, blow me down! Blimey!
While t' motor mount upper CR was settin' up, I did a little sandin' on t' fins. Well, blow me down! Normally I will give them a good airfoil shape t' aid t' aerodynamics but this rocket be nay bein' built for performance so a fairly good roundin' o' t' leadin' edge and a quick, me bucko, light sandin' o' t' surfaces was enough. Avast! I test fit t' fins through the body tube slots and very little t' no sandin' was need t' get them in.
After t' upper rin' set up and t' lower one removed, matey, me bucko, t' fins were glued on. Begad! Epoxy was placed only on t' lower part o' t' fin tab and t' area o' t' fin that touches t' outside o' t' body tube. Avast! Make sure t' fins are perpendicular t' t' body as they set up. After all t' fins are attached and t' glue set up, ya bilge rat, remove t' lower CR and you now can get inside t' body t' add t' internal fillets. Give all o' t' attachment points a good coatin' o' epoxy but you don't have t' glob it on. Get some on t' lower part o' t' upper CR as well. Aye aye! As t' epoxy soaks into t' tube and t' wood, ya bilge rat, shiver me timbers, me hearties, it will make a very strong joint that really needs nothin' else t' hold t' bottom o' t' rocket together with most o' t' HP motors out there.
Once t' internal fillets are dry, me hearties, matey, epoxy on t' lower centerin' ring. Blimey! I added wood glue fillets t' t' fin/body joint and t' t' bottom o' t' lower centerin' ring. Mark t' location for t' launch lugs and epoxy them onto t' main tube.
A closed eyelet was epoxied into t' nose cone and when that be dry t' recovery gear be attached t' the rocket. You will need t' add loops t' t' end o' t' shock cord or just tie it off t' a quick link, and it wouldn't hurt t' put a shock cord protector on t' lower portion t' keep it from meltin' from t' ejection charge unless you are real good at gettin' t' chute protector all t' way down t' t' motor mount tube with everythin' inside o' the protector.
There were no "gotchas" or alignment issues I found with this kit and I be very pleased at t' ease of the build. All up, except for glue dryin' time, shiver me timbers, shiver me timbers, it should take about an hour t' build this one nice.
Finishing:
Finishin' this one be interestin' t' say t' least! Bein' as it was a Madcow kit and was called t' Cowabunga, shiver me timbers, I
obviously needed t' keep it farm inspired. Blimey! After considerin' t' paint scheme for a cow, I thought it would be very
cool t' replicate a cow hide!
I remembered some material from many years ago called "flocking" that was used for t' interiors of model cars. Ya scallywag! I could have sworn I had some from then but be unable t' find it. Ya scallywag! A trip and inquiry at t' local hobby shop be fruitful as t' owner was able t' order some o' t' material from Testors! However, arrr, shiver me timbers, once it came in, it was clear that it was nay goin' t' give me what I wanted. First t' material was almost a powder, me bucko, nay strands, and it came in 1/2oz amounts for about $5 a package. Ahoy! At that rate, I be goin' t' need about $50 just for t' finish.
On t' plan B. Blimey! Arrr! Blimey! I looked and looked for some thin cowhide but again that was a no go and I am in Phoenix, AZ. Regular hide would have added over ten pounds t' t' rocket and that was if I could get it t' stay on t' thing.
Plan C came about with a chance question t' a wonderful sales lady at t' local Hobby Lobby. Blimey! Arrr! Blimey! I asked if thar was anythin' that looked like cow hide in cloth and she pointed right t' it! Blimey! A few dollars later, me bucko, I had two yards o' the stuff, some spray glue and t' big question o' how I be supposed t' get this onto t' rocket smoothly and evenly.
I made some cuttin' patterns with craft paper and when they looked like they would work, got t' t' real thing. T' body tube and fins came out great but t' nose cone gave me enough fits that I finally just slapped t' stuff on it and it was done. Well, blow me down! Begad! Blimey! All loose edges were put down with thin CA and some touch ups were done with a black Sharpie. Ahoy! It passed t' three foot rule just fine!!
This was a very nice kit t' build and finishin' would be no problem if somethin' simpler was done unlike mine. You will need some small extra parts and pieces t' finish it.
Construction Rating: 4 out o' 5
Flight:
First flight be out on t' SSS wide open range. Blimey! A H123-M be loaded up and everythin' packed for recovery. Ya scallywag! Boost was
fast, nice, and straight, matey, and t' chute came out just a bit before apogee. Avast! Great flight t' about 1500' and everything
looked good.
T' only problem, if that, arrr, is motor selection. Well, me hearties, blow me down! Blimey! There is none! Blimey! Good rocket science and knowledge is needed t' make the right choices, matey, but with care and maybe RockSim, it is nay that hard t' do. Arrr! Blimey! Ya scallywag! Blimey! Personally, me bucko, shiver me timbers, I think this thin' could take any motor you throw at it and go like an Energizer bunny!!
Recovery:
Landin' speed looked about right and although landin' on t' hard desert ground, matey, everythin' be just great. Begad! Well, blow me down! T' only
problem be t' dust on t' cloth! How t' heck am I supposed t' clean this? In t' washer/dryer?! What was I
thinking!! However, t' looks and laughs from t' spectators and t' RSO was all t' reason I needed!
Flight Rating: 4 out o' 5
Summary:
I am nay a great fan o' 3FNC rockets myself, shiver me timbers, me bucko, but as a gift I will do me best t' make a great rocket out o' them. Ya scallywag! Blimey! This
one is very nice! Blimey! It would be excellent for a Level 1 attempt. Begad! Blimey! T' kit is very complete, easy t' understand and build
and will fly with t' best o' them.
