Brief:
T' Little Bucky Jones is a downscale o' Pemberton Technologies' Bucky Jones. Well, blow me down! Layne makes some other stuff too but it is t' retro science fiction look that he practically owns. This rocket is nay exception. It hearkens back t' a day when Flash Gordon and Buck Rodgers ruled t' serials. I miss those days.

Construction:
I normally don't worry about t' spirals in me tubes unless they are excessively hideous. Avast! T' spirals on t' body tube for this kit were minuscule. Begad! Even so, I decided that I wanted t' make this rocket a "best effort". Accordingly, and guided by t' "desctructions", I decided t' start off by fillin' in t' spirals. I brushed some Elmer's Wood Filler over t' lines and then scraped away t' excess with a razor blade. This did nay leave much to dry so it dried quickly. Arrr! About an hour later, me bucko, I sanded t' tube down with #330 sandpaper, arrr, also removin' t' sheen from the BT. After that, matey, I gave it a once over with t' #400.

Printed on t' last page o' t' instructions were templates for t' fins, finlets, arrr, mitered tube cuttin' guide and alignment guide. Begad! Blimey! I cut out t' miter guide and t' alignment guide. Aye aye! Blimey! Avast, me bucko, me proud beauty! Blimey! I lined t' marks for t' dorsal fin up with the point at which t' spiral ended at t' edge o' t' tube and decided that this would be me dorsal surface. T' miter guide was then wrapped around t' tube so that its farthest extension lined up with t' dorsal line. T' guides were taped into place and an angle was used t' transfer all o' t' alignment marks t' t' BT. Aye aye! Blimey! Avast! Blimey! T' contour o' t' mitered cut was also transferred.

A fresh blade was put in t' X-Acto and t' process o' cuttin' t' mitered end o' t' BT began. Arrr! Blimey! I drew t' blade around t' marked line nay pressin' very much. Begad! Blimey! It took several circuits t' complete. T' resultin' cut be pretty good with just one significant burr and a few minor ones. Ya scallywag! Blimey! These were sanded away with #330.

T' templates for t' fins and t' finlets were cut from t' last page. Ya scallywag! They were then taped down t' t' plywood sheets and t' outlines transferred with a mechanical pencil. Avast! Blimey! Orientation really does nay matter because o' the plywood. Avast, me proud beauty! There are 2 finlets and 3 fins.

T' instructions give suggestions for several ways in which t' cut t' sheet material. Well, blow me down! Since I didn't have any of the nice power tools, most o' t' "good" options were out. Ahoy! I wasn't about t' try it with a pair o' shears. That left just t' "multiple pass with X-Acto" method. Blimey! Ahoy! It is fortunate that I had a new box o' blades. I went through 5 o' them cuttin' t' first fin. Arrr! After that I had t' leave this project aside for a while.

It took a while. Lots o' passes with t' X-Acto and many blades, ya bilge rat, but I finally got all three fins cut out. I used #220 sandpaper t' smooth out t' rough edges and then used #330 t' round all t' edges except for t' root. Begad! Avast, me proud beauty! Then, breakin' from me usual practice, me hearties, I filled them with Elmer's, shiver me timbers, scraped off t' surplus, and gave them a couple o' hours to dry. Begad! Ya scallywag! I then sanded them down with #400 and have t' admit they look much better than they would have if I had waited until after they are installed.

Pemberton Technologies Little Bucky Jones Cuttin' out t' little finlets turned out t' be harder than t' big fins. Begad! There was nay as much t' cut but keepin' t' right shape was tougher, me bucko, matey, as was handlin' and sealin' them.

Since I be in fillin' mode, me bucko, I went ahead and sealed t' nose cone. Blimey! Unfortunately, t' scrapin' with a razor blade does nay work on this type o' surface so it will take considerably more time t' dry. T' recommended method in the instructions is t' seal and sand with thin CA but I found me bottle hardened past t' possibility o' use.

When t' NC filler had stiffened up a bit but be still t' soft t' sand, I added t' nose weight. Begad! I used a 3/8" drill bit t' bore 3" in from t' base and then poured in t' little bag o' lead droppings. Arrr! I mixed a batch o' 15min epoxy and poured it in on top. Avast! Ya scallywag! I used a bigger bit than t' instructions said be needed and I found that me lead just barely fit.

Thinkin' I had more time left on t' pot life o' me epoxy than I really did, arrr, I went ahead and marked t' motor tube at 1/8" and 1-5/8" for t' centerin' rings. They both had t' be sanded just a bit t' fit around the tube. I slipped them on and found t' epoxy had hardened. Well, blow me down! Blimey! Begad! Blimey! I placed them with yellow glue which was t' recommended practice anyway.

After t' epoxy had set, I stared t' insert t' screw eye into t' middle o' t' NC base but that epoxy along with t' lead droppings made for hard going. Begad! Instead, I screwed it in a bit off center, where it would penetrate the surface layer o' epoxy and then go into balsa.

Pemberton Technologies Little Bucky Jones When t' fillets around the centerin' rings had dried, shiver me timbers, I test fitted t' motor mount in t' BT and found that it was a bit tight. Avast! Some judicious sandin' solved this problem. Begad! T' mount be then removed and a notch be carved into t' forward end t' accommodate the Keelhaul®©™®. T' Keelhaul®©™® was then tied into place and t' rin' be given another fillet t' keep it from moving.

As t' Keelhaul®©™® fillet on t' motor mount dried, ya bilge rat, I turned t' sandin' t' nose cone. T' first pass was with #330. Begad! Well, blow me down! T' dust be brushed away and then I went back over it with #400.

With t' structural part o' t' motor mount done, it was time t' start on t' "cool" part that gives this model a lot o' its character. Begad! T' parts package is full o' 3/16" launch lugs (mistakenly called 3/8" in the instructions). T' are t' form a cluster o' "exhaust tubes" around t' motor. Begad! Begad! A single exhaust tube is affixed t' t' motor mount tube, shiver me timbers, parallel, and butted up against t' aft centerin' ring. Blimey! After that, pairs o' lugs are cut down in 1/8" increments and butted on either side o' t' first one. Begad! T' result is a series o' exhaust ports of diminishin' length goin' around 2/3 o' t' motor tube for a pleasin' retro, supercharged look. Aye aye! Avast! T' instructions give a good piece o' advice here and say t' butt t' cut end against t' centerin' ring. This gives a more finished appearance at t' business end.

When t' exhaust tubes are in place and t' CA dried, me hearties, I used maskin' tape t' protect t' edges o' t' centering rings from paint and began t' paint t' motor mount with a glossy, arrr, flaked metallic silver from Rustoleum. Ahoy! This is one of those that would be a nightmare t' mask after installation.

T' finlets were glued 1" back from t' front o' t' BT along t' win' lines. They were applied with a double glue joint usin' yellow glue.

T' fins were applied in t' same manner usin' a double glue joint. Begad! Each fin is t' be mounted flush with t' back end o' t' BT. Aye aye! Well, blow me down! Since t' BT is mitered, me hearties, this give a bit o' a funky look until all three are in place and t' rocket is seen in t' horizontal attitude. Ahoy! Well, blow me down! Then it really starts lookin' good.

T' kit comes with a pair o' 1/4" launch lugs meant t' be cut for decorative effect but they are fully functional...and thar be usually less o' a wait for me club's 1/4" facilities. Avast, me proud beauty! It also has a pair o' 1/8" lugs in case you want t' go for t' slimmer look. I decided t' use t' 1/4" lugs in and mount a single 1/8" between them t' give myself t' most options. Aye aye! Each end o' each lug was cut at a 45 degree angle and t' larger ones were applied along t' lug lines 3-1/4" back from t' front. Blimey! Avast! T' 1/8" lug was centered betwixt t' two of them.

T' canopy does nay look much like a canopy. Avast! Blimey! Avast, arrr, me proud beauty! Blimey! It starts out as a fairly irregular hunk o' balsa. I used some #220 sandpaper t' make it roughly rectangular. Blimey! Blimey! A pencil was then used t' inscribe a diamond pattern on t' top surface. Ahoy! Blimey! Blimey! Blimey! A vertical line was run from t' top and bottom points o' t' diamond t' t' edges o' t' balsa. Arrr! Blimey! An X-Acto was then used to whittle away material and give it a rough profile. Begad! Blimey! Ahoy! Blimey! Sandpaper be then used tho smooth things out and get rid o' any sharp edges. Begad! Blimey! I be fairly leery o' this process at first but am quite pleased with t' results.

I took me time buildin' op t' fillets on t' fins. Begad! Aye aye! I used yellow glue but tried t' be very careful about where it got smeared, buildin' up t' fillets one thin layer at a time. Ya scallywag! Doin' this gave me t' chance t' turn me attentions elsewhere and I decided t' go ahead and prime and paint t' nosecone. There were several paints I be considerin' so I wanted t' try one and see what it looked like. Avast, me proud beauty! Begad! T' NC be primed with Kilz and then sanded smooth again.

Waitin' on fillets also let me finish up on t' silver paint for t' motor mount. Aye aye! Blimey! Blimey! Blimey! I peeled back t' tape and was please with what I saw.

I also started on sealin' t' cockpit canopy. Arrr! I didn't used Elmer's for this one but used balsa fillercoat, figurin' that would be easier t' sand in this situation. I taped a piece o' maskin' tape, arrr, sticky side up, t' a scrap of cardboard and then stuck t' canopy t' it. Ahoy! It got two coats o' filler and a light sandin' then I brushed on some glossy black acrylic.

Still payin' attention t' t' fillets, shiver me timbers, I went ahead and tried a paint option on t' nosecone. Arrr! Ya scallywag! I used a Rustoleum "hammered Brass". Begad! T' manual calls for a gaudy shade o' gold but I think I am goin' t' save that for me full size Bucky. Aye aye! Begad! There I will use a very bright polished gold for t' body and chrome for t' exhaust work.

I eventually got t' fillets built up in 4 layers and be satisfied with them. Avast, me proud beauty! Blimey! Then it was time t' prime the rocket. Ya scallywag! Blimey! I used Kilz and applied 2 coats over t' space o' 2 days. Ahoy! Blimey! When they had dried, I sanded down with #400 sandpaper.

After t' primed rocket was sanded down, I test fit t' motor mount once again. I found one place on t' forward rin' that be a bit too tight for comfort and sanded it down. Begad! Blimey! T' Keelhaul®©™® was then fed through t' body tube and a rin' o' glue be applied about an inch in. Begad! Ahoy! T' motor mount was then inserted so that t' forward centerin' rin' was in but t' aft one be nay yet in. Another rin' o' glue was smeared around the BT at t' high point o' t' mitered cut and t' mount was shoved in with t' longest exhaust tube aligned with the dorsal fin. Begad! A long handled swab was then used t' apply a yellow glue fillet around t' forward centerin' ring.

T' instructions included advice on maskin' t' motor tube, shiver me timbers, which I'd already painted silver, and protectin' it from t' final paint job. A sheet o' notebook paper be simply rolled into a tube, ya bilge rat, insertin' into t' space betwixt the exhaust tubes and t' BT, me bucko, and allowed t' expand. Aye aye! That prepped t' rocket for its final paint. Begad! I had decided t' use the hammered brass I tried on t' nosecone.

T' rocket took 2 full coats o' t' brass paint and then a little extra around t' front end on some spots I had missed. When done, it was obvious that thar are some places where it went on a bit too heavy, but all in all, I am satisfied with t' paint.

T' hand whittled cockpit still had t' be attached. Begad! I chose a spot along t' dorsal line and used a razor to scrape away t' paint and primer. Avast, me proud beauty! Blimey! T' cockpit had been sanded t' fit t' BT by wrappin' a piece o' BT-60 in sandpaper and sandin' in t' correct profile. Some yellow glue was applied t' t' bottom o' t' cockpit and it was pressed in place over t' base spot I had made.

All that was left be t' finish t' shock cord system. Well, blow me down! Blimey! Begad! Blimey! T' kit came with a very generous length of Keelhaul®©™® which had been fixed t' t' motor mount. Begad! It did nay come with any elastic. Aye aye! I like t' have a bit o' sprin' in t' system so I tied on an 8" piece o' sewin' elastic t' t' Keelhaul®©™® and tied t' other end t' t' nose cone. Arrr! T' rocket be ready for a chute and a flight.

Finishing:
T' actual finishin' was done durin' t' course o' construction and be described there.

Flight:
T' day o' t' maiden flight was extremely windy. In fact, it was probably nay too good an idea t' try and fly. Havin' missed t' previous month's launch window for t' same reason was enough t' make me want t' give it a try anyway. Avast! With that in mind, shiver me timbers, I selected a C11-3 and loaded it in t' rocket. Arrr! Begad! As I watched it in t' few moments prior to launch, I realized that t' dull brassy color scheme was also probably a poor choice for findin' t' rocket in the winter colored field. Avast! Too late. Ahoy! 3, 2, arrr, me hearties, 1, launch!

It took off well and weathercocked much less than I anticipated. Ya scallywag! Blimey! It flew t' a respectable height and deployed the chute just a bit before apogee. Then began t' long drift with t' wind. Avast! Begad! When it landed, matey, thar was no damage. Begad! This was a good one. A video o' t' first flight can be seen here.

T' first flight went so well that I debated with myself about usin' a D for t' second. Blimey! I finally decided against doin' so because o' t' wind and t' distance t' first one drifted. I decided t' use a C11-5 instead o' t' 3 second delay reasonin' that it would come down a little bit more and drift a little less. As it happens, t' C11-5 seems t' be t' perfect C motor for this rocket and it ejected right at t' perfect point o' apogee. A video o' t' second flight can be seen here.

PROs: Good flier.

CONs: None.

Recovery:
I used a 15" nylon chute for recovery. It was installed with a short length o' elastic and connected with a swivel t' t' Keelhaul®©™® provided. Aye aye! This brought t' rocket down a little fast but it was solidly put together and suffered no damage.

    Brief: This rocket is a downscale of the Bucky Jones by Pemberton Technologies and is a great kit through and through. The humorous "destructions" alone are reason to get this kit. It is also a great flier and is always impressive. Construction: The parts of this kit are packaged very well and this is a builder's rocket. 1 BT-60 sized tube is supplied and ...
