Conversion o' t' Mustage Kit:
Remove t' fins and launch lug. Begad! Begad! Cut off t' top o' t' body tube so that the length is 14-1/8". Ya scallywag! Avast!

Buildin' t' RamJet:
Cut t' 10.5mm body tube t' a length o' 11". Blimey! Aye aye! Then mark it on each side the length o' t' body tube. Begad! Begad! Cut tube in half lengthwise. Arrr! (save t' other half for the Dorsal Conduit) Take t' plastic 10.5mm nose cone and mark it usin' the halved body tube, then cut it in half lengthwise. T' total length for the RamJet support is 12-1/2".

Cut each o' t' (5) vanes o' t' RamJet from t' basswood strips. Arrr! Following the SLAT/s instructions, me bucko, me hearties, cut and sand each vane into t' proper shape. Arrr! Then glue each one onto t' 10.5mm body tube makin' sure t' back o' t' vane is even with t' back o' t' tube. Also each vane edge that attached t' t' 10.5mm tube should be touchin' t' one next t' it.

Cut t' Icarus body tube t' a length o' 10-3/4".

Once dry, matey, ya bilge rat, lay this assembly onto t' Mustang body tube so that it is hanging off t' back. Arrr! Aye aye! Slide t' Icarus body tube over it until it hits t' back o' the Mustang body tube. Ya scallywag! Ahoy! Mark where they meet on t' Icarus tube. Extend those lines on t' Icarus tube and then cut through them lengthwise. Don't use an enlarged guide for these two cuts. Begad! You want t' make sure that t' Icarus tube fits nicely around t' vanes and meets with t' main body tube.

Next, me bucko, you will need t' cut out t' front shape o' t' RamJet usin' a template. Ya scallywag! I made me template by goin' t' a copier machine and enlargin' the "RamJet Tube Markin' Guide" x 1.9x. Avast! Then on t' front (followin' the SLAT/s instructions) cut 1.5" lengthwise and 1/4" from t' edge to form t' front o' t' RamJet.

Mark t' Mustang body tube, usin' an enlarged "Body Tube Marking Guide" and a door jam. Avast! Avast! Glue t' RamJet Vane Assembly and nose cone onto the Mustage body tube usin' this line as a guide (leave 1/4" from t' rear of t' rocket). Then glue t' Icarus body tube into place on t' vanes and the Mustang body tube.

Buildin' t' Dorsal Conduit:
Take t' other half o' t' 10.5mm body tube that was cut in half lengthwise and cut it t' a length o' 8-1/4". Aye aye! Take t' 10.5mm balsa nose cone and mark it usin' t' halved body tube, shiver me timbers, then cut it in half lengthwise. Arrr! Take some sandpaper and attach it t' t' Mustang body tube. Well, blow me down! Avast! Rub t' nose cone halves on that sandpaper t' form them t' t' body tube. Avast, me proud beauty! Glue t' tube and both halves o' the nose cone onto t' Mustang body tube on t' exact opposite side (follow instructions) o' t' RamJet. Ya scallywag! T' tip o' one nose cone should just be shy o' the top o' t' body tube (where t' nose cone fits). Arrr! Begad! T' total length for the Dorsal Conduit is 10-3/4".

Build t' Fin Assembly:
After carefully cuttin' t' balsa parts from t' original SLAT/s sheets, shiver me timbers, I took the empty sheets t' t' copy machine. Begad! Blimey! Begad! Blimey! I then used t' enlarge button until I had t' correct length on t' copy. Ahoy! Blimey! (Pod base t' 5-5/8" for a reference). This became me template t' cut out t' balsa pieces for t' upscale.

Follow t' SLAT/s instructions for buildin' t' pods. After buildin' the pods, me hearties, take some sandpaper and attach it t' t' Mustang body tube. Ahoy! Blimey! Rub t' pods on that sandpaper t' form t' edge that will be glued t' t' body tube.

Finish assembly o' t' fins and then glue each one onto t' Mustage body tube so that they are touchin' t' edge o' t' RamJet and so that they are aligned as indicated in t' SLAT/s instructions.

Finish or . Aye aye! Well, me bucko, blow me down! . Blimey! .
At this point, shiver me timbers, you could finish t' rocket out by attachin' t' parachute and recovery system t' t' nose cone. Begad! Then add enough nose cone wait t' make the Center o' Gravity is equal t' 12 3/4" from t' nose cone w/o t' motor. (never more that 14-1/2" with a motor).

. Avast, me proud beauty! . Aye aye! . Beyond:
In me case, I decided t' add dual deployment and an electronics bay. Ahoy! Blimey! Blimey! Blimey! This may seem impossible with t' length and diameter o' this rocket but just let your imagination go for a minute.

Preppin' t' Nose Cone:
First you will have t' cut out t' very bottom o' t' nose cone, just above the round in t' shoulder (the shoulder should still have 15/16" o' material left). Begad! Next tie 2' o' 3/16" Keelhaul®©™® to an eye-bolt (the one I used had an 1/2" eye and be about 2" in length). Well, blow me down! Then take a file or small screw driver and scratch up t' inside of the nose cone tip about 2" from t' tip. Well, blow me down! Avast! Blimey! Then get a large glass o' water with some ice in it. Ya scallywag! Aye aye! Blimey! Put t' nose cone into t' glass o' water so that t' open in facin' up and support it there. Aye aye! Hang t' eye-bolt into t' nose cone so that is it all t' way in and touchin' t' tip and yet still straight up and down. Then mix up some 30 minute epoxy and drip it into t' nose cone until it reaches t' eye-bolt. Blimey! Blimey! Keep addin' it until t' bottom o' t' eye-bolt is just submerged that way it will form a "bridge" through t' eye-bolt. (Note: I don't know if it is necessary t' submerge in cold water, however, I didn't want any heat reaction o' t' epoxy curin' t' melt t' nose cone).

Buildin' t' Electronics Bay:
To create t' Electronics Bay you will need a 5" piece o' tubin' (I used a nice 38mm motor tube since it is thick). This will need t' be sized by cutting a strip out o' it lengthwise until when held together it is a snug fit into the nose cone (You'll want 1-3/4" t' fit into t' nose cone). Aye aye! Avast! Once t' fit is right, me hearties, glue t' seam together and also place a thin paper strip on t' inside of t' tube for strength. Arrr! Then soak t' section o' t' tube that will extend into t' nose cone with CA. Well, blow me down! Sand it. Arrr! Soak it. Ahoy! Begad! Sand it. Ahoy! Blimey! Soak it. Blimey! Avast, shiver me timbers, me proud beauty! Sand it until it is smooth, strong and fits snug into t' nose cone. This fit will need to hold together at t' apogee deployment since t' nose cone will contain the main parachute.

Once t' tube is sized and fits right, arrr, arrr, then a wooden bulkhead will need to be glued onto t' top (section that slides into t' nose cone). Avast, me proud beauty! I used a wooden bulk head and a 1.16" thick, 1-1/2" washer on t' inside o' t' tube. I had t' use me dremel t' size t' washer correctly. Drill a hole in t' center and mount an large eye-bolt. Aye aye! Blimey! I used one with a 1" eye, 1/4" thread, and a total length o' 2-1/4", shiver me timbers, arrr, me hearties, along with two hex nuts, ya bilge rat, ya bilge rat, one for each size. Don't worry you need t' weight. Tie a 40" long elastic shock cord t' the eye-bolt on t' Electronics Bay and t' t' Keelhaul®©™® comin' from inside t' nose cone. I used Aerotech's elastic.
