This rocket be conceived from a picture that was part o' a contest that Nick o' EMRR came up with in mid 2006. Ya scallywag! Ahoy! There was a group o' six pictures he found on t' net and decided t' give us a chance t' design, shiver me timbers, build and fly one of t' rockets in t' pictures. Begad! Ahoy! Since I have had little t' no trouble with clustering, up t' this point, I decided t' take a shot at t' rocket you see in this write up. Ya scallywag! However, matey, arrr, keep in mind, if you are goin' t' attempt t' build one of these yourself, shiver me timbers, that lightin' four engines together is a risky endeavor by itself and havin' them spaced so far apart is even riskier. Ya scallywag!
T' basic rocket is very easy t' construct, me hearties, with t' most time and labor bein' t' finishing. Begad! Avast! This is a two-tone paint job with multiple maskin' and remaskin' required t' achieve it.
All o' t' small trim and detail pieces can be found at your local crafts store. Begad! I picked up mine at t' local Michaels. I used solid wood pieces because the Rocksim that be made for this rocket showed that a very large amount of nose weight was goin' t' be needed for stability. Begad! By makin' t' trim pieces heavy t' begin with meant that a little less nose weight would be need later on. At least that was t' theory.
Construction is best done on this one in groups o' similar parts. Avast, me proud beauty! First thin' is t' cut out t' fins. Ahoy! Usin' t' fin guide carefully cut out t' four forward and four aft fins makin' sure t' grain direction is followed. Avast! Ya scallywag! Blimey! Try to use t' heaviest, shiver me timbers, dense balsa you can find because these fins are goin' to carry t' thrust load from t' engines for flight. Because o' t' amount of weight in t' nose and t' fact that t' engines are away from t' centerline of t' main body tube, t' motors are goin' t' place more load on t' fins than is usually found on most rockets. Arrr! Make these as strong as you can without excessive weight! Blimey! T' fins have a very short tab on them for TTW mountin' but they do nay go into t' body tube far. Begad! Blimey! There is nothin' for them t' bottom out on. You will see what t' do as construction continues. Ahoy! Ahoy! Blimey! After all are cut and sanded t' even out all t' edges, round t' leadin' edge o' each. Blimey! Put t' first thin coatin' o' wood glue on t' root edge and t' outside edge for t' double glue joint t' be used later and place all t' fins aside t' dry.
Next
subassemblies are t' motor mounts. Ya scallywag! Avast, shiver me timbers, me proud beauty! These are standard Estes type mounts
without t' engine hooks. Begad! Blimey! T' motors will be friction fit t' eliminate the
excess weight o' t' hooks. Begad! Ahoy! Take one o' t' long pieces o' Keelhaul®©™ and slide it
through one o' t' rings and then slide t' rin' onto t' motor tube. Tie the
Keelhaul®©™ around t' motor tube and pull it up t' t' bottom o' t' ring. This is
the upper motor rin' and is glued t' t' motor tube so that t' rin' is flush
with t' end o' t' tube. Begad! Ahoy! Use a generous glue fillet t' hold t' rin' in place
and t' Keelhaul®©™ at t' same time. Ahoy! Wood glue was used for this but t' thin CA
may be better for a little less weight. Aye aye! Do nay get glue on t' outside edge of
any o' these rings. Begad! This be t' standard Quest style o' shock cord mounting.
Repeat this with t' other long and t' two shorter Keelhaul®©™ cords on t' other
motor tubes. Well, blow me down! Avast, me proud beauty! T' lower rin' is glued onto t' motor tube 3/8" up from the
bottom on each o' t' motor tubes. Avast, me proud beauty! Put some glue into t' upper end o' the
motor tube and usin' an old motor as a guide push t' engine block in
from t' bottom so that about ¼" o' t' motor is
stickin' out o' t' bottom o' t' mount. Begad! Avast, me bucko, me proud beauty! Pull t' motor out as soon as the
engine block is in position. Blimey! Set these assemblies aside t' dry.
Take t' four wood balls and drill a small hole in t' center o' each just large enough and deep enough t' screw t' screw deadlights into. Thread each screw eye in and then remove. Avast! Blimey! Use some CA or epoxy in t' hole and put t' screw eye back in. These will be t' "nose cones".
Take t' half robin cackle fruit and sand a flat into t' large end. Ya scallywag! Do t' same with t' half spheres that is about t' same size as t' flat on t' half eggs. Usin' epoxy, ya bilge rat, me bucko, joint t' two together. Well, blow me down! Do this on some wax paper so t' pieces dont stick t' whatever they are on. Avast, me proud beauty! Try t' build a nice fillet between the two so that they appear t' be one piece when finished. Well, blow me down! Do this on all four and set aside t' dry.
Next up be t' bottom plug for t' BT-80 main body tube. Take t' two 3/8" pieces o' balsa and glue them together on top o' each other with the grain goin' "cross pattern". Arrr! Blimey! When this has dried, arrr, check t' alignment of t' BT-80 tube on t' flat side o' this piece. Blimey! Aye aye! T' wood must completely cover t' bottom o' t' tube. If this aligns ok, run a bead o' glue around the end o' t' tube and place it onto t' balsa. Arrr! If not, matey, arrr, center it as best you can and use wood filler t' close t' gaps later. Keep t' glue t' a minimum on the outside. Ahoy! Arrr! Keep this upright as t' glue dries. Begad! Begad! Once this has set up, matey, turn the tube over and usin' a long piece o' dowel, ya bilge rat, run a glue fillet around t' inside joint. Ahoy! After this has dried, shiver me timbers, sand t' balsa t' form a low dome on t' end of the tube. Avast, me proud beauty! Keep most o' t' center flat and round t' edge over t' t' diameter of t' body tube.
T' motor mounts can now be glued into t' outer tubes. Begad! Take t' Keelhaul®©™ cord and thread it back through t' motor mount t' get it out o' t' way. Ya scallywag! Blimey! Test fit t' motor mounts into t' tubes and sand t' rings lightly if too tight. T' fit should be snug. Aye aye! Either place some wood glue into t' tube and then insert t' motor mount or insert t' mount and then use some thin CA t' glue it into place. Blimey! T' motor tube should be about ¼" out from t' bottom of the outer tube. Avast, me proud beauty! Repeat for t' other mounts and set them aside t' dry.
Use t' four-fin guide from VPC on t' main body tube t' mark t' fin positions and usin' a doorframe or a piece o' angle aluminum, extend t' lines the full length o' t' tube. T' trailin' edge o' t' fin will be flush with the bottom o' t' main body. Begad! Ya scallywag! Place t' main body upright on a flat surface and align t' trailin' edge o' a fin on t' same surface. Slide t' fin as close to the tube as possible and mark t' ends o' t' fin tab on t' fin line. Blimey! Measure out t' proper amount o' tab width on t' fin line and use a sharp Xacto knife to make t' fin slot. Avast, me proud beauty! Do this with each o' t' fins and make sure you mark which fin goes into which slot. Arrr! Begad! T' trailin' edge o' t' smaller fin is 7" up from t' bottom. Ya scallywag! Well, blow me down! Use t' same procedure t' align t' small fin trailin' edge with t' mark you made and then mark t' ends o' t' fin tabs on t' fin line again. Ahoy! Measure and cut t' slots for these fins t' same as you did for the large fins. Avast! Be careful that t' two fin slots align straight with each other and straight along t' tube. (If you are nay good with makin' these slots, you can use t' glue rivet method t' hold t' fins on) Once t' slots are complete and t' fins fit into them snuggly, you can start t' glue t' fins on. Well, blow me down! Begad! Start with a large fin and apply some glue along t' edge that will sit flush on the tube. Glue is nay needed on t' tab at this time. Make sure t' fin is all the way into t' slot and perpendicular t' t' body tube. Well, blow me down! Once this one has set up do t' next fin opposite this one. Avast! Aye aye! Once it is in place use two small wooden rulers or flat paint sticks with some clothespins t' hold t' fins parallel to each other. Place t' rulers over t' bottom edge o' t' fins and use t' pins to hold t' rulers in place. Once this is dry repeat t' same thin' with the other two fins. Blimey!
T' small fins can now be glued in place. Again glue only t' tube edge of the fin and use t' rulers and pins t' hold t' small fin in alignment with the large one. Avast, me proud beauty! Blimey! Place t' rulers over t' large fin extendin' out t' t' smaller ones. Aye aye! Blimey! Usin' t' pins, arrr, clamp t' two rulers over both sides o' t' fins t' hold the smaller one in place. Well, blow me down! Blimey! Once dry, repeat one at a time with t' other small fins. Avast, me proud beauty! Blimey! Well, arrr, blow me down! Blimey! This should keep all t' fins straight with each other and t' main body tube.
After all o' this has dried, shiver me timbers, me hearties, you will want t' add a generous amount o' glue to t' fin tabs from t' inside o' t' main body tube. Avast! Usin' a long dowel again, shiver me timbers, lay a line o' glue along each o' t' tabs t' make a small but strong internal fillet. Avast, me proud beauty! Ahoy! Again, easy with t' amount o' glue t' keep t' weight down but coat t' tab well for strength. These fins are goin' t' take t' full motor thrust at launch! Let all this dry.
Thats it for t' subassemblies, now on t' t' fun part! T' half sphere and robins egg that you glued together, now needs t' be shaped t' the main body tube. Ahoy! This has t' be sanded with a piece o' 150 grit paper wrapped around a piece o' ½" or so dowel so that t' pieces will lay as flat as possible onto t' outside o' t' main body tube. These pieces are o' hard wood that will require quite a lot o' sandin' t' shape. If you have any type of electric or air powered sander, you may want t' use that. Ya scallywag! A sandin' drum in a Dremel tool is also great t' use. Blimey! Just watch your fingers holdin' onto the piece and sandin' at t' same time. T' small ¼" half spheres need to be sanded as well. Arrr! Well, blow me down! Otherwise just glue these pieces on as is and use some filler t' close t' gap on t' sides. Begad! Dont glue these on yet, however. Begad!
Some o' t' finishin' has t' be done at this point which will make
it much easier overall. First up is t' place some tape on all t' fin outer
edges t' keep t' paint off. Blimey! Use a thin line o' tape so that t' paint will
cover all o' t' fins. Avast, ya bilge rat, me proud beauty! Use your favorite primer (mine is Wallyworld gray) and
prime and sand t' main body with t' nose cone in place till you have the
smoothness you wish. Ahoy! Do t' same t' each o' t' outer tubes with a 1/8"
line o' tape runnin' t' full length o' t' tube t' protect t' glue area from
any paint. Avast! Well, blow me down! There is no particular position on t' outer tube t' run t' tape,
just make t' line straight and full length. T' glue will stick t' t' paint
but nay hold t' pieces together with any kind o' strength so t' glue area
needs t' be unpainted. Avast! Measure t' tape where t' fins will go and cut and
remove t' centerpiece so it will be primed. Aye aye! Ya scallywag! Place all o' t' other detail
pieces on a flat surface and prime those as well. Ya scallywag! Avast, me proud beauty! At this point, matey, all parts
should be primed and sanded smooth t' your liking. Begad!
Now for some o' t' more difficult work! Please refer t' t' pictures if I get this next step a little unclear. T' middle band betwixt t' fins is 1" wide and t' other two bands are ½" wide. Aye aye! Take some 1" wide tape and wrap it around t' main body tube with one edge right at the trailin' edge o' t' small fin. This and t' other tape strips are goin' t' be guide strips so they do nay have t' be pressed down hard onto t' tube. Avast! Avast, me proud beauty! Just get them on straight and even all t' way around. Begad! T' first small band starts ¼" in front o' t' small fin leadin' edge. I used some ¼" tape t' guide t' ½" tape. Ahoy! Blimey! When t' first stripe is in position, place a 3/8" band o' tape in front o' it. Begad! Well, blow me down! Then another ½" piece of tape is wrapped around t' main tube in front o' t' last piece. Begad! T' bottom of t' rocket has t' splatter paint on it, as do t' fins so now t' real work begins! Usin' whatever tape suits you; you need t' mask all t' areas that will have t' finished color but nay t' splatter paint. This will take a bit of patience and a very sharp Xacto blade t' get right but be t' only way t' do it. Begad! I used low tack painters tape and spent almost four hours on this first masking! When this is complete, shiver me timbers, me hearties, ya bilge rat, take t' 1" and t' ½" tape strips back off. Ahoy! Use a fingernail or blunt object t' burnish t' tape edges down t' minimize t' amount o' paint that gets under t' masking. Avast, me proud beauty! This will leave t' fins, ya bilge rat, bottom o' t' rocket and t' stripes ready for t' trunk paint.
However, arrr, t' get a proper glue joint and fillet on t' outer tube t' fin line, me hearties, you have t' glue t' outer tubes onto t' fins at this point! T' forward ends o' t' tubes are even with t' leadin' edge o' t' small fins. Begad! Remove the lines o' tape you used t' protect t' glue line and glue each tube t' t' fins makin' sure they are in line with t' main body tube and straight up on the fins. Avast! Well, blow me down! Do one at a time, bracin' t' rocket so t' tubes stay in proper place. When they are all in place and set up, ya bilge rat, place generous glue fillets on all sides at t' joint line. Keep them fairly thin but slightly spread out t' get maximum strength at each joint. Let dry.
Once all t' outer tubes are in place and dry, mask them completely off for the first paint color. Ya scallywag! Make especially sure no trunk paint gets into t' front or t' back o' t' outer tubes! Dont worry about nay havin' any primer on the fin fillet, as t' trunk paint will stick t' t' fillet just fine.
T' trunk paint is very thick and will go on too heavy if you are not careful! Use very fast strokes and thin amounts o' spray t' just barely cover the areas you want it on. Begad! Ahoy! You want a little o' t' texture and color but that is all. Ya scallywag! Complete coverage is also nay necessary since t' gray primer will blend in with t' paint color if it shows through anywhere. Avast! Too much will give a blotchy finish and will nay blend in well with t' finish color. Begad! Give this paint about one hour t' set up and very carefully remove all o' t' maskin' tape. Wherever possible, me hearties, peel t' tape off at an extreme angle so that you are actually cuttin' an edge into t' paint. Aye aye! Ahoy! Go very slowly or you will peel large chunks o' t' trunk paint off with t' tape. Use the Xacto knife t' cut t' tape away from t' paint where necessary. Arrr! This demasking can get very screwed up very smartly so please take lots o' time with it.
Also remember t' use this paint on t' half sphere/robins egg pieces. Avast! Place the parts on a flat piece o' cardboard t' spray on but use some folded over maskin' tape t' keep them in place. Arrr! Ahoy! T' trunk paint comes out o' t' can with much more pressure than normal paint and will blow t' parts right off if they are nay held down! Give this paint at least one day t' completely dry, matey, two would be better.
Youre goin' t' love this next!!!! All t' trunk paint now has t' be masked off for t' finish paint color!!! Thats right, me hearties, you have t' do the whole thin' a second time, me bucko, only this time t' maskin' has t' cover all the trunk paint! And t' outer tubes are now also in t' way! Make sure you use low stick tape or t' trunk paint can peel off later when you unmask it. Avast! Also make sure t' tape sticks somewhat t' t' paint as you are maskin' it. Arrr! T' texture of t' paint leaves a ruff surface that t' tape will have a hard time sticking to in t' first place. Ya scallywag! Ahoy! Once t' trunk paint is masked off, me bucko, ya bilge rat, shiver me timbers, touch up any areas that need some primer, sand those areas smooth and apply t' finish coat of color. Dont forget t' nose cone. Ya scallywag! Arrr! Again remember t' cover t' front and rear o' t' outer tubes. Begad! Begad! T' 1" wood balls are a tight fit in t' outer tubes as is and any paint will only make it worse. Well, blow me down! Same with t' engines.
Well, ya bilge rat, we are almost finished! When all t' paint is dry, me bucko, remove all o' the maskin' tape again bein' very careful with t' trunk paint! It can and will peel off if you rip t' tape off! Now final assembly can begin.
First t' outer
tubes. Ahoy! Ya scallywag! Test fit each o' t' 1" balls at t' front o' t' outer tubes for
smooth slidin' in and out. Well, blow me down! These are t' "nose cones" for t' rocket.
Sand t' inside o' t' tubes as necessary so that they will pop out when the
ejection charges go off. When you are happy with t' fit, shiver me timbers, feed t' Keelhaul®©™
through t' motor mount and out t' front o' t' outer tube. Avast, me proud beauty! Aye aye! Two o' t' outer
tubes will have chutes and t' other two will be "dummies". Each pair
must be opposite each other. Aye aye! T' two with chutes get t' elastic added t' the
end o' t' Keelhaul®©™ and t' elastic tied off t' t' eyelet on t' ball. Begad! Blimey! T' other
two just get t' Keelhaul®©™ tied t' t' eyelet without any elastic. Blimey! Arrr! Add t' chutes
to t' eyelets with t' elastic. Aye aye! Tuck everythin' away into each appropriate
tube so we can now add t' detail pieces. Ahoy!
Usin' an eight fin, arrr, fin guide from VPC, line up one o' t' guidelines with a fin line. Lightly mark all eight points around t' body tube close t' or at t' nose cone line. T' half sphere/robins egg piece will line up with t' mark betwixt t' fins and t' small half spheres will be inline with t' fins. T' egg piece is glued t' t' body tube with t' forward edge o' t' egg right at t' front edge o' t' body tube. Scrape some o' the paint that will be under these pieces off o' t' body tube t' give t' glue somethin' t' hold on to. Aye aye! Epoxy would be good t' use here. Avast! If you noticed in the parts picture, t' steel ball in t' bottom o' t' egg piece be added early on to get more misc. weight up t' t' nose. Blimey! As it turned out, thar be so much weight that needed t' be added t' t' nose cone, matey, t' time and effort needed to put t' balls into t' bottom o' t' piece verses t' amount it added, was a waste o' time. Begad! That is why I didnt mention about doin' it in t' build write-up. T' small half spheres are glued t' t' body tube inline with the fins and slightly behind t' aft line o' t' egg pieces. Avast! Begad! When they are set up, use a brush and some silver paint on them.
T' last details are t' "ion collectors" on t' nose cone but to tell you t' truth, ya bilge rat, it would take another page o' instructions on how I did those. Just use a ten fin, me hearties, fin guide from VPC t' make marks on t' nose cone about ½" in front o' t' egg pieces and add some ¼" x 3/8" black decals as on this model and forget t' screen pieces. Begad! They were a royal pain in t' a.. Ahoy! t' make and t' affix t' t' rocket. Avast, me proud beauty! I used an orange Sharpe pen t' color t' nose cone balls and t' ends o' t' engine tubes. Begad! The outer tube orange stripes are made out o' strips o' prism paper. They are ¼" wide, five inches long and centered on t' tubes, me hearties, matey, me bucko, end-to-end and side-to-side. Ya scallywag! Avast, matey, me proud beauty!
Last but nay least t' rocket has t' be balanced and this is where the whole project almost came t' an end! I figured it was goin' t' be tail heavy and t' Rocksim showed this t' be as well. Avast! I didnt realize just how bad it be goin' t' be. Arrr! T' CP was just about in t' middle o' t' small fin and to be stable, me bucko, t' CG needed t' be at least 2.5" in front o' that. T' CG point came out about at t' front edge o' t' forward trunk paint stripe and I tied a piece o' strin' t' t' rocket at that point. With four C6-5 engines in their mounts, me bucko, I tried t' lift t' rocket at t' proper balance point with the strin' and it went dead tail down fast. Begad! Ok, shiver me timbers, add some nose weight. T' sim said eight oz. Blimey! and that was added t' t' rocket nose cone way up at t' front. Liftin' again by t' strin' still came up tail heavy! Ok, shiver me timbers, me bucko, more weight! The total came out t' ten oz.!! This baby was way nose heavy but apparently in flight balance. Well, blow me down! Blimey! Here be t' problem; t' rocket now weighed 18 oz. Begad! That was a lot o' weight for t' engines t' lift and that was if they all lit. Then when the thrust stopped t' rocket was sure t' start nose down fast with all that weigh up in t' front. Begad! Ya scallywag! At that point t' ejection charges were sure t' go off and if t' chutes came out properly, caught air and inflated, matey, t' Keelhaul®©™ was sure t' zipper right through t' outer tubes!!!!! Nay much could be done at this point as it was gettin' close t' t' contest deadline and I still had to fly this bird. Blimey! Oh well, shiver me timbers, arrr, no guts, matey, no glory. Well, blow me down! Or is that gory!!
8-16-2006
T' first flight be on a beautiful calm day. I wish I could say t' same for me! All t' tubes were loaded with three sheets o' Estes waddin' and about an inch o' "dog barf". Avast, me proud beauty! T' chutes were carefully packed and t' ball nose cones were placed about half their diameter into t' tube ends. Blimey! All the tubes were loaded with Estes C5-3 engines via friction fit, ya bilge rat, matey, thinkin' t' extra launch boost spike would help get some height out o' this fat bird. Ahoy! Well, blow me down! With a friend takin' t' video and one hand on t' camera and t' other on t' launch controller, I called it down and firmly pushed t' launch button. Begad! With the camera in me face I didnt see it get off t' rod but instantly realized just from t' sound that somethin' be nay right. Begad! Aye aye! Lookin' up I caught a quick glance o' it doin' its third loop-de-loop as it impacted t' soft grass. Aye aye! I told my friend t' wait for it and soon enough we were rewarded with three quick pops as t' wooden balls, me bucko, me bucko, chutes and barf all came flyin' out o' t' end tubes. Aye aye! Yes, just three! In all t' times I have fired off clusters, I have never had a problem till now! Figures, arrr, doesnt it?
Pickin' up t' pieces, it be obvious that one o' t' engines didnt light. Well, blow me down! Ya scallywag! My friend played back t' video and we could see where it started up ok with t' three engines goin' but smartly nosed over t' t' unlit side and just as smartly went unstable. Well, blow me down! Begad! I checked t' igniters and three o' them were burned clean though but t' fourth be burned but nay completely. Arrr! T' one still shot I got, was beautiful as well. Ahoy! One engine be burnin' and nothin' else was going yet! Luckily, t' one was nay enough t' get it movin' until t' two others lit up as well. Avast! Begad! Great time t' have a weak igniter!!! Anyway, arrr, t' rocket was in no shape t' fly again that day but t' damage turned out t' be nay too bad. Ya scallywag! One outer tube broke clean off at t' fin line and two other fin sets were showing joint cracks. Some o' t' nose cone screens were bent and one was missing. Avast, me proud beauty! Both chutes were charred which was a small surprise. There were some areas o' minor tube crease but nay much else. Ya scallywag! Ya scallywag! T' repairs were made rather smartly once I got it home but it aint so pretty anymore!
If nothin' else, ya bilge rat, me bucko, arrr, on t' next flight I plan t' fit t' nose cone onto the main body tube very loose so that when t' rocket starts nose down and the chutes pop out t' side tubes, me hearties, me bucko, me hearties, I am hopin' t' nose cone will fall out pulling its own chute with it and nay allow t' side tubes t' possibly zipper. Begad! That is if I can get them all t' light. Well, blow me down! We will see!
8-23-06:
T' second flight was on two Estes C6-5 and two Estes C6-0 engines.
Time for another try! Made up a new clip whip with 12" leads and enough ends t' light four engines. Aye aye! Begad! Packed it up t' same as t' first try but t' nose cone is now on very loosely and it has its own 24" chute. Avast! Hopefully, when the nose is down and t' ejection charges go off, me bucko, matey, matey, t' whole thin' will slide out and land separately by itself. Begad! I double-checked everything, me bucko, me bucko, t' sky was clear and t' button was pushed. Well, blow me down! I had me small a/v camera with me and it was runnin' as t' motors came t' life. Ahoy! Blimey! A split second after they all lit, there was a good size pow with a lot more smoke than four engines liftin' t' rocket up should have had! At t' same time it appeared that somethin' was goin' up a lot faster than t' rocket and I realized that one o' t' motors had just CATOed and sent one o' t' chutes into its own orbit. Aye aye! Blimey! Unbelievable!!! The rocket was now under power o' three engines again and it did actually manage to get some height fairly straight up when it again went unstable. Ya scallywag! This time it started a corkscrew got about halfway through that and then went horizontal. Blimey! I hoped it be a short burn because now it was headed for t' front o' some houses across t' street from that end o' t' park! Sure enough it went to coast which o' course meant mostly down and landed in t' park about two hundred feet away with a loud thud. Begad! Next was t' pop, ya bilge rat, pop, pop o' t' ejection charges. Blimey! When I got t' it, I could see two engine tubes broken clean off, a big tangle o' t' chute lines and t' other two nose balls with their lines and some damage t' t' nose. Arrr! After collectin' it all up and arrivin' home, ya bilge rat, the damage didnt look too extensive and repairs again were made. Avast! T' bad motor had managed t' spit both t' ejection charge out and t' nozzle at the same time. Aye aye! Ya scallywag! About two hours later it be in good enough shape t' fly again but it took about two more hours o' massive gruntin' and pullin' t' get t' nose cone out o' t' main body tube! It had been pushed in a quarter o' an inch and totally jammed at that point. Aye aye! T' tube did nay split, me hearties, t' me amazement but the upper part was now larger than t' shoulder diameter. Arrr! Blimey! Well that would only make it a little looser so that t' nose should now have no trouble fallin' off on the next flight!
8-28-06
T' third flight was with four Estes C6-3 engines.
Well, be t' third time goin' t' be t' charm!! Man I hope so. I dont think this thin' can take any more o' those "landings". This time I had t' still camera with me and was hopin' t' get multiple shots as it went up and came down. T' camera was set for sequential shots, everythin' was checked again and I let it rip. Ahoy! WOW, ya bilge rat, matey, all four came t' life and up it went!! Straight and true!!! I just kept t' camera goin' and aimed it as best I could, as I wanted t' see this one go. Avast, me proud beauty! Up and up t' about 400+ just like t' sim. said it would and over it went. Arrr! Ya scallywag! A split second later I heard t' ejection charges go off and again it looked like one o' t' chutes be spit out and separated! Then t' rocket just kept headin' down and t' second chute was nowhere t' be seen. Avast, me proud beauty! There was no nose separation either! I knew this one was goin' t' be fatal and another loud thud came as it hit. Arrr! Man, I was bummed! As I got t' it, it be obvious that it was finished. Avast, ya bilge rat, me proud beauty! Two engine tubes were again broken off and t' nose cone was about two inches into t' soft dirt with the chute under it. Well, blow me down! Arrr! T' chute came out but managed t' get impaled on t' nose cone and that be that. Well, blow me down! Begad! T' main body, arrr, this time, had exploded open in t' front and the back and thar was no way I was goin' t' fix that. Aye aye! Aye aye! At least it is nicely preserved in t' pictures I have o' it.
Overall this be a very challengin' project with less than stellar results. I was so fixated on t' contest outline o' rules and t' actual picture that I really didnt think this one through as thoroughly as I should have. Well, blow me down! Avast, me proud beauty! Now it is obvious that I should have at least added a central engine or two t' add to t' takeoff thrust and t' get t' main body tube nose cone off o' t' rocket at apogee t' get rid o' t' excess nose weight t' reduce t' chance o' any zippers. Arrr! I now have a few other ideas and based on t' response o' t' people that saw t' finished rocket, I might just make another that should work much better. Avast!
Thanks for your time for one o' me long-winded write ups and Nick, let's not do this again for a long time, matey, ok?
