Brief:
This is a plastic model conversion o' t' Revell Authentic Kit o' t' Convair ISX-SSC model. Ya scallywag! Begad! This was an eBay buy from earlier in t' year and be t' 1996 issue o' t' kit. Ya scallywag! This comes up on eBay quite often and can usually be won for a small, shiver me timbers, reasonable price. Ahoy! T' original came out in 1959. Those are goin' for some outrageous amounts and you would nay like t' mess up that kit with this conversion. Arrr! Well, me hearties, blow me down! I remember assemblin' it as a kid myself. Avast, me hearties, me proud beauty! I had got it as a childhood reminder, but months later after inspectin' t' kit, I found an important part missin' and just stashed t' model away. Begad! Avast, me proud beauty! I was goin' t' attempt a F-104 conversion but could nay figure out just how t' do it. While searchin' for somethin' else, I came upon this kit again and realized that it would make an excellent model t' convert t' flyin' status for t' EMRR 2006 Challenge.

Construction:
T' kit itself is a very basic build with several sections that would come apart on t' display model but will be glued together t' fly. Well, shiver me timbers, blow me down! T' lower booster section is an excellent piece for t' addition o' a 18mm body tube/motor mount with t' upper stages fastened together t' form t' nose cone. This would allow for plenty o' power for flight with a small, fairly heavy rocket. Well, blow me down! For this conversion, arrr, you will need t' following:

• All o' t' first stage parts
• All o' t' second stage parts
• All o' t' third stage parts (mine was missin' t' third stage engine unit bulkhead)
• All o' t' Glider Unit except t' cabin bottom, cabin top and crew figures
• One BT-20 tube, ya bilge rat, 5 1/16" in length
• One BT-20 coupler tube, 1 7/8" in length
• Two CR-2050 rings (the thick green ones)
• One CR-520 for a motor block
• 6" o' 70# Keelhaul®©™ for shock cord mount
• 24" o' 1/8 elastic for t' shock cord
• Launch lug, arrr, 1/8" x 1"
• One 10" t' 12" chute (keep it thin, AKA Estes)
• Some extra clear, shiver me timbers, stiff plastic for two add on fins
• Thin and thick CA, arrr, ya bilge rat, 5-minute epoxy, and some plastic glue

Construction starts with t' first stage booster parts. Arrr! Ahoy! Take t' upper and lower bulkheads and add one 2050 centerin' rin' t' each one. Blimey! Aye aye! Make sure you add t' rings t' t' side that goes into t' booster body on both bulkheads. Begad! T' rings should easily center into t' bulkheads by eye. Begad! Use some thick CA on t' rin' edge and place into t' bulkhead end. Well, matey, blow me down! When t' CA has set up, arrr, me bucko, use a drill or knife t' open up t' plastic on t' inside o' t' rings. Take out just enough for t' body tube t' fit in snuggly. Avast, me proud beauty! T' upper bulkhead will be easy t' do but t' lower one will take some work. Try t' open it up without completely destroyin' t' engine nozzles. Ya scallywag! If you are careful, most o' t' outboard nozzles will be left for show. Test fit t' fuselage parts together with t' bulkheads. Avast! Arrr! Trim t' plastic as necessary for a good fit. Aye aye! Ahoy! T' parts on mine fit well enough that they stayed together without glue. Begad! Test fit t' BT-20 tube into t' fuselage. T' bottom end should be flush with t' bottom o' t' bulkhead restin' on a flat surface and t' top should be flush with t' top bulkhead or just slightly below it. If everythin' fits well, use a good plastic cement or thin CA t' put t' first stage booster together. Arrr! Do nay glue t' BT-20 in at this time.

Take a used 18mm motor and wrap some ¼" maskin' tape around t' nozzle end just as if you were goin' t' use it for flight. Begad! Blimey! Aye aye! Blimey! Test fit t' motor block slightly into t' BT-20 tube and if OK, arrr, pull it out and add some wood glue t' t' inside o' t' BT-20 about 1.5" in. Ahoy! Blimey! Insert t' motor block and usin' t' old motor as a spacer and push t' block into t' tube in one continuous motion till t' tape stops it. Avast! Blimey! Pull t' motor out right away and let t' glue set up. Avast! Blimey! Don't stop or do this slowly or t' motor block will "grab" and nay be far enough in t' take t' motor. Once this has set up, shiver me timbers, me bucko, measure down from t' top o' t' tube t' t' motor block and transfer this measurement t' t' outside. Ya scallywag! Blimey! Make a very small hole at t' mark, which should now be just above t' motor block inside. Avast! Blimey! Arrr! Blimey! Use some thin CA t' harden a very short part o' t' Keelhaul®©™® (1/8" or less) and insert it into t' hole from t' outside. Well, blow me down! Well, blow me down! Feed it through and out t' top o' t' body tube. Take that end and make a small loop in t' Keelhaul®©™® for t' later addition o' t' elastic shock cord. Aye aye! Pull t' Keelhaul®©™® back inside o' t' tube till t' loop is just inside t' tube. Arrr! Take a small piece o' maskin' tape t' tape t' Keelhaul®©™® t' t' outside o' t' body tube at t' other end. Well, blow me down! Make this a flat as you can. Avast! Use some thin CA t' hold all o' this in place. Aye aye! Begad! When dry, cut off any excess Keelhaul®©™® and set it aside.

Usin' t' fins on t' first stage as a guide, matey, make an outline o' t' shape onto some paper and transfer that outline t' t' clear plastic. Aye aye! You will need t' make two more fins out o' this t' aid t' stability o' t' rocket for flight. Blimey! Without t' extra fins, arrr, me hearties, matey, t' rocket would have all o' its fins in one plane and would tend t' take off straight and then most likely go horizontal and try t' fly like an airplane. Ya scallywag! No use feedin' t' rocket gods right away in you can help it! Once you have t' extra fins cut out and smoothed t' edges, me bucko, you will need t' mark t' first stage fuselage for them. Aye aye! Begad! Keep t' new fins centered betwixt t' original ones so that you will have a standard four-fin rocket when they are attached. Keep these new fins flush with t' bottom o' t' rocket so it will be able t' stand on its own as well. I roughed up t' area on t' fuselage where t' new fins would go t' give t' glue some extra bite. Blimey! Begad! Use some thin CA t' tack them on and finish with some 5-minute epoxy for t' fillets. Avast, me proud beauty! Take it easy with all o' t' glue on t' lower part o' this rocket, it is heavy enough as is.

Add a 1/8" x 1" long launch lug t' t' fuselage about ½" down from t' top. Avast, me proud beauty! Well, blow me down! Blimey! Keep it on t' round side o' t' fuselage and just clear o' t' added fin.

T' most difficult part o' t' conversion is next. Arrr! T' second, arrr, third and glider stages need t' be modified t' form t' nose cone. Begad! This took me t' most time and be done "on t' fly" with many "look see" sessions before actually cuttin' anything. Aye aye! Avast, me proud beauty! I had no spare parts in case a mistake was made! For this kit, me bucko, I had t' make a third stage lower bulkhead, which was t' missin' part I discovered earlier. It be t' white plastic piece in t' pictures. Ya scallywag! Once that was done, ya bilge rat, I needed t' add t' coupler tube t' t' parts which was t' become t' nose cone shoulder. After careful consideration, I had a plan!

Take t' second stage parts and assemble them per t' model instructions. Avast, me proud beauty! Blimey! Do t' same with t' glider section but leave t' interior parts out. Glue t' canopy t' t' glider instead o' leavin' it loose. Begad! Blimey! Blimey! Blimey! Add t' third stage engine unit bulkhead (the piece I had t' make) t' t' third stage fuselage bottom but don't glue t' third stage plate on yet.

Test fit all o' t' upper stages together now and adjust as necessary so they can all be glued together later. Arrr! They will all be needed together as well t' help in fittin' t' coupler into t' second stage so that they will be straight and true with t' first stage.

Take t' BT-20 tube and reinstall it into t' first stage booster. Begad! You may have t' notch t' lower CR slightly t' pass t' Keelhaul®©™® bump on t' outside through. Ahoy! Arrr! Blimey! Once in place, take t' coupler tube and insert it into t' top o' t' BT-20 about 1/3 o' t' way in. Begad! Begad! Blimey! This will be your guide for notchin' t' second stage booster t' fit. Ya scallywag! Keep t' locatin' pins on t' second stage for now and usin' a knife or round sandin' block, ya bilge rat, slowly start takin' material out o' t' bottom (flat) side o' t' second stage. Open up both o' t' end pieces t' fit t' coupler tube. Arrr! Blimey! Keep checkin' t' fit t' t' first stage as you go and stop when t' coupler fits into t' second stage and t' second stage fits flat onto t' top o' t' first stage with t' pins in place. Ya scallywag! Blimey! T' glider section on top o' t' second stage booster is used t' form t' upper stop o' t' coupler.

T' third stage lower bulkhead will have t' be opened up t' same way so that t' third stage will fit flush with t' other two stages and t' first stage body when assembled with t' tube coupler in place.

Use t' third stage and glider section as necessary t' keep all t' pieces aligned with t' first stage. Ya scallywag! If t' coupler is fitted at an angle, ya bilge rat, t' nose cone will nay be straight t' t' first stage. Ya scallywag! You will be takin' all three pieces and fittin' them together and takin' them apart many, many times! But in t' end t' nose section o' t' new rocket will be a nice fit. Aye aye! Ya scallywag! T' notch doesn't have t' be very pretty because when completed, it will be out o' sight except when t' two pieces are apart for recovery.

T' flat piece for t' third stage has t' be notched for t' coupler as well and don't just open it up t' t' coupler diameter. Aye aye! It actually fits slightly t' one side. Well, blow me down! You could just cut it off at t' bottom t' clear t' coupler but t' extra material on either side o' t' coupler gives you some extra surface t' hold t' whole thin' together.

T' glider piece be t' only section that needs no modifications for t' tube coupler.

Once you are satisfied with t' fit o' all t' pieces and t' tube coupler t' each other, remove t' coupler and usin' t' centerpiece from a CR-2050, me bucko, glue this t' form a cap onto t' coupler t' seal one end. You can use some extra glue when workin' on t' nose cone parts t' add some extra weight t' t' upper part o' t' rocket for stability. Ahoy! I used 5-minute epoxy on most o' this assembly.

Final assembly can now be started. Ya scallywag! Arrr! First cut a small slit into t' cap and feed t' shock cord through until about ½" is left outside. Fold this over onto t' coupler and epoxy it t' t' coupler. Ahoy! This will secure t' cord t' t' nose cone. Avast, me proud beauty! Glue t' second stage booster and glider section together usin' t' third stage t' keep them flat with each other. Avast! Do nay glue t' third stage t' t' other stages yet! Once set up, arrr, me hearties, remove t' third stage pieces and glue t' coupler into t' second stage so it is up against t' bottom o' t' glider section. Begad! Use glue only on t' inside o' t' second stage t' hold t' coupler in and make sure t' shock cord "bump" is facin' out. Begad! Add t' third stage flat piece t' this next and add any additional fillets as needed now. Ahoy! Keep t' third stage half round piece loose for t' time being. Avast, me proud beauty! When dry, me bucko, attach t' other end o' t' shock cord t' t' Keelhaul®©™® and test fit t' whole assembly together. T' coupler piece should be a snug fit but loose enough t' eject. Begad! Blimey! Adjust as necessary.

Attach t' chute t' t' shock cord a few inches down from t' nose cone. Avast! You will have t' set this point by trial and error. Ahoy! Blimey! Pick a spot on t' shock cord t' attach t' chute, ya bilge rat, pack t' whole thin' up and blow t' nose cone off. Aye aye! When t' chute comes out as it should, ya bilge rat, me hearties, you have t' proper spot. Avast! Avast, me proud beauty! You may have t' pack t' chute into t' coupler and t' shock cord into t' main body or vice versa. Ahoy! Aye aye! There is nay enough room t' pack t' whole thin' into t' body tube.

Put t' whole thin' together again and load an engine as well. Aye aye! Usin' some string, find t' balance point. Ya scallywag! It should be about 3.5" up from t' bottom. Ya scallywag! Wherever yours is, tape it in place and do a swin' test. Begad! Arrr! Add clay t' t' loose third stage piece if needed t' allow t' rocket t' swin' forward properly. When t' rocket is balanced properly, finish t' assembly by gluin' t' third stage piece t' t' others. Ahoy! My rocket did nay need any extra weight for stability.

Finishing:
I have nay painted or added me decals. Arrr! T' tell t' truth, I am at a loss as t' what, me hearties, me bucko, if any, color t' use. Begad! I was thinkin' along t' lines o' a silver rocket with standard Space Shuttle cAolors for t' glider section. Arrr! However, bein' as this is an old rendition o' t' shuttle we have today, me hearties, I am also tryin' t' come up with a retro style paint scheme. Whatever you decide t' do, make sure you use model paint for plastic from a hobby shop. T' automotive and Krylon type o' paints will eat up t' plastic because o' their "hot" solvents.

Flight and Recovery:
I was able t' get three flights in at our last club launch with different engines. Well, blow me down! Preparation o' this one is tedious at best due t' t' tight constraints o' t' small tubes. Avast, me proud beauty! Ya scallywag! Blimey! I used tweezers t' help load t' shock cord and shroud lines. Avast! Blimey! Very little waddin' will fit but try t' get at least two sheets in. A 10" diameter chute be used with lots o' powder t' make it as slippery as can be.

T' first flight be with an Estes B6-2 engine, arrr, arrr, thinkin' t' short delay would be needed in case o' any trouble. Aye aye! T' help with t' lack o' waddin' in t' body tube, arrr, shiver me timbers, I added one sheet into t' open area at t' top o' each motor that be used. Aye aye! Actually, t' rocket shot off o' t' pad, givin' me no liftoff shot and reached about 300'! T' ejection was a tad early and although t' nose separated, shiver me timbers, t' chute was nay out. T' whole thin' came in fairly flat and bounced at least a foot back up when it hit t' ground! Close inspection revealed no damage luckily and it be prepped for t' next shot.

Thinkin' I was goin' t' have more problems with that chute, ya bilge rat, I loaded up a Quest A6-4 next. T' rocket again shot smartly off t' pad and got about 50 t' 75' up when t' whole thin' went unstable. Blimey! That was a big surprise and it landed hard but flat. T' ejection charge then went off which appeared t' pull t' chute out. Well, blow me down! Begad! It appeared t' go unstable just after motor burnout. T' chute came out this time but it obviously didn't amount t' much! I think t' rocket just didn't have enough forward velocity at burnout t' remain stable for flight. It didn't get very high and in retrospect, matey, didn't appear t' be movin' too fast as well.

Hopin' t' third time t' be t' charm, shiver me timbers, ya bilge rat, it was loaded up with a B6-4. I wanted t' try a C engine but be afraid it would be too much power and get too high. If t' chute again failed t' deploy, arrr, I didn't want it t' shatter on impact. Ahoy! Blimey! This time t' flight be stable and ejection occurred just after apogee. T' chute came out but now decided t' nay open! Blimey! Down it came, matey, slower this time but just as hard as t' first. Avast! Blimey! Aye aye! Blimey! That be it for t' day as one o' t' added on fins completely popped off at t' attachment point. Well, blow me down! Blimey! It was repaired later with no other problems.

So far no really successful flights, as far as all t' systems working, me bucko, me hearties, but it has turned out t' be a very strong and resilient build t' this point. With any luck I will have a completely workin' flight before it shatters from another bad one.

Summary:
This was a bit o' a challenge t' construct for t' conversion but t' kit itself lends itself very well t' do this. Arrr! Blimey! It is stable with enough power and t' 18mm motor mount allows this. Although t' finished model is small, ya bilge rat, me hearties, thar be ample room for a nice size motor mount.

PROs: Easy model build with a conversion challenge that is well within t' average modelers skills. Avast, me hearties, me proud beauty! Simple rocket lines with old school design without pesky details just askin' t' be broken off on t' first bad landing! It displays nicely on t' shelf as well.

CONs: Tricky addition o' t' nose cone shoulder. Very small model, shiver me timbers, easy t' lose with too much power. Aye aye! Aye aye! No usable paint scheme t' finish kit.

This was a fun project that allowed me t' use a possible junk kit do t' missin' parts and turn it into a flyin' model rocket that many people were interested in when it was brought t' t' RSO table. Ya scallywag! It also strengthened me adage that almost anythin' can be made into a rocket and fly!
