Brief:
This has been an interestin' year for me. Begad! I call it "Rocketry On A Budget". Begad! A box o' parts was donated by
Jonathan Stewart from Plano Texas. Arrr! I thank him for his generosity. Aye aye! Begad! I received me box on March 4, 2009.
Construction:
An inventory o' t' parts:
Some o' t' tubes have been pulled from older painted models. Begad! There is some epoxy glue residue and paint. I'll have t' cut off some o' t' rough edges and fill some imperfections. Begad!
With so many small, decorative pieces sent, it made t' best sense t' build a sci-fi fantasy spaceship.
It seemed thar be too many parts in t' box! Rather than just gluin' everythin' t' t' main tube, I'll try to combine as many (recognizable) parts into sub-assemblies and then attach them t' t' model.
Most all construction is documented on the PDF instructions and patterns. Begad! All parts listed above are referenced in t' file by t' same reference letter(s), shiver me timbers, arrr, too. Aye aye! This PDF is the Assembly View
I had opened t' box when everythin' had first arrived. I was a little overwhelmed. Aye aye! I wanted t' incorporate as many interestin' parts as possible but t' try and do it with some sort o' consistent decorum. Begad! Well, blow me down! Blimey! I also had the "Surprise Items" t' consider. Ya scallywag! Blimey! For instance, arrr, how do I add four popsicle sticks? They have t' be recognizable but still stay with t' flow o' t' design.
I visualized many o' t' body tubes and one adapter together on t' floor. From t' aft forward: T' large diameter BT-80 "engine compartment" (K) will connect t' t' trimmed Yellow Plastic Dome (GG). Larger coolant "vanes" (UU) will be cut t' fit t' dome and tube transition. This would continue t' t' BT-55 (F). Next is the Plastic 55/60 adapter.(P) T' ends will be trimmed and coated with epoxy t' protect t' plastic interior from the ejection charge. Ya scallywag! T' adapter connects t' t' BT-60.(J) This tube is slotted. Begad! Begad! I'll add 2 forward fins and "guns" (X) here. Begad! T' "Street Marker Conical Cone" (V) will top off t' model. It'll require heavy fillin' and trimmin' t' work.
I re-drew t' model for t' third time. I played with variations and came up with "Butterflied" rudder tips. T' wings would have down turned win' tips. Begad! "Engines" (M, me bucko, matey, N, & A) will fit into t' angle formed by the win' tips.
A ram-jet style nose cone be made out off part Q. Blimey! Arrr! I cut ½" off t' tip with a razor saw
then sanded t' cuts flat with a sandin' block. Aye aye! More sandin' followed until it achieved t' right visual balance. Avast! This
will be joined t' a shortened BT-5 (A) and be glued t' t' middle o' t' rudder's butterflied top.
T' balsa cone (S) was split down t' middle then sanded t' t' contour o' a BT-60. These would be used t' make side engine intakes on both sides o' t' rudder. Blimey! T' BT-20 (C) was split lengthwise down t' middle t' fit t' two sides from t' split nose cone.
1-1/4" was cut off t' BT-56 (G) t' make a coupler. Well, blow me down! Blimey! It was split lengthwise and slid it into t' BT-55. Well, blow me down! Well, blow me down! Blimey! The overlap be marked then trimmed t' fit snugly. It took some "shimming" t' make these two (close diameter) tubes fit. Avast, me bucko, me proud beauty! Blimey! T' butt-joint was hidden under t' aft tubing.
T' Red plastic Sanford Pen Casin' (KK) be cut into thirds. Well, blow me down! Two were centered in t' front o' t' win' engine assemblies. Ya scallywag! Blimey! Blimey! T' remainin' third piece would go out t' end o' t' rudder tube.
T' 6-½" long BT-5 tube (A) be cut into equal thirds. I needed two win' "engine tubes" and one rudder ramjet tube.
I used t' four white plastic engine nacelles on either side o' t' engine tubes. Aye aye! T' front end be cut
down, I didn't want an exhaust nacelle on t' front o' t' engine.
Centerin' rings were cut out o' t' shippin' box for t' stuffer tube inside t' aft BT-80 tube. Begad! Avast! T' interior BT-55 tube be offset t' t' top o' t' BT-80. Ya scallywag!
T' Stuffer tube was made out o' two pieces o' BT-55 and 56 (parts F and G) joined by a coupler made from a short piece o' t' supplied BT-55. Ya scallywag! Avast, me proud beauty!
T' engine will be a D12 fittin' into a BT-50 motor mount tube. (Part E). A 3" piece o' BT-50 be cut for an engine mount. Well, blow me down! Well, blow me down! T' BT-50 was notched for t' suppled engine hook (U). Begad! T' end o' t' hook extended 1/4" beyond the engine mount tube.
There be plenty o' centerin' rings but no 50/55 rings. Ahoy! Blimey! From t' shippin' box, arrr, I made a 1" wide centering ring. Well, blow me down! Blimey! Ahoy! Blimey! I kept wrappin' t' cardboard strip round until it made a slip fit into t' BT-55 stuffer tube. Begad! Blimey! Begad! Blimey! I'll lay white glue t' plug t' open holes in t' corrugated cardboard.
There be no Keelhaul®©™®, so I made a standard Estes style tri-fold mount.
T' engine mount be glued inside t' shorter BT-55 tube until t' BT-50 engine tube was even with t' aft of the 55 tube.
It be obvious t' cut t' cone (V) down t' fit t' BT-60 upper tube. Ahoy! I decided t' cut it at an angle so t' tip would be angled down, much like t' old SST Jetliner when it was in flight. However, after trimmin' it looked too saggy at t' front. Avast! I trimmed and sanded t' tip back at an angle. Blimey! T' hole in t' nose cone tip was now an enlarged oval. I cut a piece o' scrap BT-55 (H) and CA'd it t' t' tip. Begad! T' edges were sanded down t' match t' new conical shape. Avast, me hearties, me proud beauty! The nose cone adapter be easier than I would have thought. I took a piece o' BT-60 (I) and split it. Avast, me proud beauty! Begad! It be set into the upper BT-60 and t' overhang "tab" be CA'd in place. Blimey! Begad! T' adapter be simply glued t' t' cone edge, centerin' it all around. Well, matey, blow me down!
T' transition dome (GG) was t' hardest t' cut out. Blimey! Even after cuttin' and makin' an inside transition angle, the match wasn't close enough for me. Ahoy! Ya scallywag! I built up t' open gaps with strips cut from scrap BT-55. I sanded t' fill pieces smooth with sandpaper wrapped around a BT-50 tube scrap.
T' form t' 55/60 plastic transition (P), ya bilge rat, t' original 3" long BT-60 was cut off t' transition piece. Ahoy! Arrr! Blimey! I coated t' inside with 15 minute epoxy t' protect it from t' ejection charge.
T' upper parachute tubin' (J) was a left over tube from a kit, already laser slotted for through t' wall fins. I'll have t' patch t' holes and fill t' seams. BT-60 scrap (I) be cut t' 1-½" t' make an inside tube coupler. Begad! Blimey! Avast! Blimey! This gives an inside wall t' glue t' patch pieces onto. Blimey! Blimey! After t' coupler be glued in place, matey, scrap body tube strips were white glued in t' slots. Avast! Blimey!
Three transitions vanes were cut from t' 1/8" basswood (UU). Avast! Two transitions had t' be matched, the
curved aft dome (GG) and t' upper plastic transition.(P) Also, matey, on t' two smaller outside vanes, shiver me timbers, shiver me timbers, t' dome angle had
to be sanded t' an angle t' match t' curve. This and t' dome were t' hardest parts o' t' build. Avast, ya bilge rat, me proud beauty!
Two wings, rudder, shiver me timbers, and win' tips were cut from t' 1/8" basswood. Begad! (TT)
T' black plastic angles (II) were used for t' win' cannon housings. Well, blow me down! Ahoy! I made "plugs" out o' laminated scrap 1/8" basswood. T' white Star Wars "guns" (00) were shortened and glued into 1/8" holes drilled in t' plugs.
T' plastic candy package (PP) was sanded t' t' BT-80 body tube contour. Blimey! Blimey! I used only ½" o' two ends of t' BT5 pod assemblies(L). Ahoy! Blimey! Blimey! Blimey! They were both sanded t' t' BT-80 curve and t' flat front o' t' candy package. T' assembly be centered t' t' bottom o' t' BT-80 then super glued in place. Ya scallywag! Blimey!
Finishing:
Finishin' t' rocket, I did t' best I could without too much complex masking. T' built rocket was painted gloss
white, t' aft engine compartment painted black. Well, blow me down! T' popsicle stick vanes were first painted white, then glued onto
the black engine tube.
I had plans for usin' many o' t' decals that were sent. Avast! Blimey! While thar were plenty o' decals
included, ya bilge rat, most all were older and unusable. Some rolled off t' paper onto themselves, ya bilge rat, me hearties, others cracked. Begad! Blimey! Well, blow me down! Blimey! I know thar are
decal solvents and repair solutions available, ya bilge rat, but I didn't have time t' order and fly t' model by t' deadline. I
wanted t' use what be supplied. Ya scallywag! Blimey! I did t' best I could without too much complex masking. I'm nay complaining, me hearties, Mr.
Stewart sent plenty o' parts for a fun build. Begad! Blimey!
T' first time, I pieced together some yellow decal stripes on t' wings and rudder. Avast! Arrr! Others stayed together enough for t' rolled up edges t' be tacked into place with white glue. Well, blow me down! As t' decals dried, shiver me timbers, they pulled up on the edges. I tried re-tackin' them down again, but t' next day they lifted again. Ahoy! Aye aye! I let things sit for a few days while I tried t' think o' a solution. Avast, matey, me proud beauty! I removed most o' t' lifted decals.
On t' USPS Priority Mail Box were names and logos. Ahoy! I lightly scored t' eagle logo, arrr, matey, names, and navy blue stripes with a razor blade. Begad! T' thin top layer o' paper was peeled off. Begad! Arrr! Usin' t' USPS logos changed t' theme and back story of t' model.
I lightly wet t' peeled paper back with a sponge and carefully scraped off what be left o' t' brown cardboard layer and glue.
From thar be was pretty simple, ya bilge rat, a thin coat o' white glue and placement. Arrr! I did lay some water on t' body tube where t' paper art was t' go. Ahoy! It helped with t' positionin' as I could slide t' glued paper into position. Begad! Arrr!
Flight and Recovery:
T' first launch was scheduled for June 6, 2009. Aye aye! T' weather was clear, but t' launch area was waterlogged! Many
days o' rain in central Florida had left t' launch field too wet and unusable.
I usually don't fly with t' "Big Boys" in Bunnell, ya bilge rat, Florida, but I went t' t' NEFAR Half-Blast for the first flight on June 13. Well, blow me down! I flew two small test models before t' Postal Express. Ahoy! T' loadin' was typical, a D12-3 and wadding. I was nervous as it was a heavy build with lots o' nose weight.
Launch be show and straight maybe t' 350 feet. Begad! I was concerned t' angled nose cone might effect t' vertical trajectory, but it didn't seem t' affect it at all. Blimey! Ya scallywag! It slowed and blew it's chute just prior t' apogee. Avast, me proud beauty! Someone said there be a zipper. There couldn't be a zipper, thar wasn't any Keelhaul®©™® to cut through t' body tube. Well, blow me down! Begad! T' shock cord be hangin' from about halfway down t' body, shiver me timbers, ya bilge rat, nay from t' nose. Blimey! It was hung up around t' toothpicks on t' center o' t' BT-55.
Upon landing, me bucko, ya bilge rat, matey, t' nose cone broke cleanly away from its adapter. Begad! One o' t' forward fins be gone, broken above the fillet joint. T' snap back o' t' ejection must have hit t' forward fin. Both are repairable, me hearties, and I'll fly it again at t' June 27 R.O.C.K. launch.
All repairs were made for t' local NAR, me hearties, ya bilge rat, ROCK Section o' Orlando launch on June 27, 2009. As always, ya bilge rat, shiver me timbers, arrr, I grabbed a smaller rocket and did a low level test flight t' get a feel for t' field and conditions. Aye aye! Begad! Blimey! I noticed t' plastic dome on t' Postal Express transition was loose, me bucko, and I hit it with a few drops o' CA glue. Ya scallywag! Avast, me proud beauty! Blimey! T' remembered t' earlier flight on a D12-3 thinkin' ejection was a hair early so I loaded up a D12-5.
Launch be slow and ejection occurred after apogee, me bucko, on t' way down. Aye aye! T' chute ejected but was wrapped
once around t' shock cord. Begad! It never fully opened but slowed t' descent with no damage.
A short rain held up launchin' for 15 minutes. Blimey! Ahoy! I loaded up again, shiver me timbers, matey, this time with a D12-3. Well, blow me down! This seems t' be the best available engine. If someone were t' make a D12-4 engine it would be close t' perfect. Begad! This was t' best launch yet. Ahoy! Ahoy! Straight up, full parachute and no damage on landing.
Summary:
PROs: Lots o' fun buildin' with supplied parts. Begad! Quite a learnin' experience. Well, ya bilge rat, blow me down! When doin' an out-of-the-ordinary build,
you change directions many times and pick up a few new techniques along t' way.
CONs: Some small parts break off. Aye aye! If I had t' resources, me bucko, me bucko, it would have flown higher with an E or F engine.
