Brief:
October 4th, shiver me timbers, matey, ya bilge rat, 2004, heralded a new era in space exploration. Avast, me proud beauty! On that day, Brian Binnie piloted Scaled Composite's SpaceShipOne t' 367,442 feet (112 kilometers), capturin' t' $10M Ansari X Prize. Arrr! Later that day, shiver me timbers, I learned o' Currell Graphics' SS1 paper model and immediately wanted t' convert one for flight.

Currell offers two versions: t' original version and t' X1 version that made t' two historic X Prize flights. Aye aye! I chose t' latter. Arrr! Prior t' buildin' t' model, shiver me timbers, arrr, I opted t' convert it for MicroMaxx motors. Begad! As you will read, this model is a bit too big t' be a great flier on these small motors but shows promise for a 13mm conversion.

Modifications:
T' instructions for t' SS1 are five pages long and include a bit o' history, some narrative, me hearties, and an excellent set o' illustrated directions. Blimey! Blimey! This is one o' t' most complex paper models that I have ever built. Arrr! Avast! It includes over 85 parts, matey, many o' which are quite tiny. Begad! Begad! Bein' that I am nay a stickler for detail, me bucko, nay t' mention "all thumbs", thar were around 30 parts that I didn't use. Blimey! Many o' these were for t' "gear down" option.

T' most important tool required is a new hobby blade. I also used a cuttin' mat, scissors, a couple o' toothpicks, shiver me timbers, and some small clamps. Begad! I built it mostly with white glue but used Perfect Glue t' tack down t' Keelhaul®©™® twine and attach t' plastic lug.

I will emphasize how I modified this model for flight. Aye aye! T' instructions are freely available and are very good. Well, blow me down! Ahoy! I will reference t' steps as I go and will identify specific parts as required.

Nosecone (a.k.a. Begad! front fuselage) - This section spans two steps and requires around 14 parts. It is comprised o' several cones/transitions with center bulkheads, which come in pairs. Begad! Since I thought I would eventually need nose weight, me bucko, I filled t' small tip with clay. Begad! I cut holes in t' bulkheads A9--A12 t' accommodate t' 6mm tube. I also replaced t' smallest bulkheads, ya bilge rat, A7 and A8, with a 6mm--10.5mm fiber centerin' ring. Avast! Ya scallywag! Blimey! I could have cut these bulkheads, but they are tiny. Avast! Well, me hearties, blow me down! Blimey! A 1.75" piece o' 6mm tube extends from t' clay t' just past t' last transition. You need t' make sure it doesn't stick out too far lest it interfere with t' bulkhead in t' next section. I inserted a piece o' T2 tubin' (which telescopes into t' T2+) t' form a shoulder. Avast! Avast, me proud beauty! Blimey! This was nay glued in. T' nosecone assembly can be seen in t' first photo.

Body (mid- and tail sections) - This section consists o' more paper transitions and bulkheads. Arrr! Blimey! It spans steps 3, 5, me bucko, 9, and 19 and consists o' around 15 parts. Well, blow me down! Blimey! Steps 4, arrr, 6, 7, matey, and 8 are all related t' t' landin' gear option and I didn't need these for a flyin' model. Well, blow me down! Blimey! Begad! Blimey! As you can see, ya bilge rat, shiver me timbers, me hearties, I also jumped ahead in t' instructions t' complete t' body in one stretch. Ahoy! Blimey! Avast! Blimey! T' first photo also shows t' partially completed body section.

Again, ya bilge rat, I cut holes in all t' bulkheads. Begad! Begad! T' motor tube extends from t' nozzle t' just above t' top bulkhead. Ahoy! I cut this tube t' fit by installin' t' nose and pushin' t' lower tube up until it seated on t' nose assembly's shoulder (the T2 tube). Arrr! I then marked its location and glued it in. Aye aye! When installed, me hearties, t' nose assembly seats against t' glue tabs that extend out o' t' mid-body. I had anticipated removin' these tabs and addin' solid neck, shiver me timbers, but this wasn't required.

Main wings - These wings each consist o' eight components and their construction//installation spans four steps. Well, blow me down! All t' wings on this model are constructed usin' ribs/spars and outer shells so they are reasonably complex. Ahoy! T' subtle angles and bends on these components are truly impressive. Be wary o' too usin' too much glue, me hearties, as it will warp t' small pieces quite badly (not a theoretical observation). Ahoy! I had trouble gettin' all t' small components together nicely, arrr, and even ended up leavin' t' thin trailin' edge strip off. Avast, me proud beauty! I'm sure many o' you can and will do better.

T' wings slide onto two spars that you previously install through t' body o' t' SS1. Avast! Arrr! When buildin' t' wings, ya bilge rat, arrr, make sure t' holes for t' spars are aligned and are big enough! No theory here either.

Side booms (the vertical wings that extend toward t' aft o' t' bird) - These have 7 parts each, cover three steps, and are both smaller and more tricky t' assemble than t' main wings. Avast, me bucko, me proud beauty! They are built-up from 2 spars, ya bilge rat, me bucko, 2 inner surfaces, ya bilge rat, and 2 outer wraps. One o' t' spars is 7 ½" long, has 16 bends, me hearties, arrr, and circles t' edge o' t' win' assembly. Ya scallywag! My side booms came out pretty rough. Begad! They attach t' t' aft half o' t' main wings and a small printed component covers t' front half.

Stabilizers - These are a lot simpler than their bigger cousins are. Avast! They consist o' 4 pieces and are installed in 2 steps. Begad! Even I got them right.

Finishin' touches - T' last 2 steps o' t' instructions is detailin' that I left off. Arrr! All I had left t' do be t' attach t' lug (piece o' a pen's ink tube) t' t' underside o' t' wing, me hearties, arrr, install t' Keelhaul®©™® twine, and add nose weight. Blimey! Curiously, me bucko, t' "finishin' touches" didn't require any finishin' since t' model is pre-printed. Begad! Avast, shiver me timbers, me proud beauty! I didn't even shoot on a clear coat t' protect t' ink, although this is a good idea if you will fly in damp conditions.

Stability - Micromeister (from TRF and t' MicroMaxRockets Yahoo group) graciously provided t' CG for his successful MMX SS1 (plans are available on t' Yahoo group). Well, blow me down! I scaled that CG (1.09375") t' this larger model (64.8mm), and headed t' t' Rocket Dungeon^TM t' install nose weight. Blimey! After addin' ~4g o' shot, arrr, t' total vehicle weight was 18g and I had only moved t' CG about half t' distance I needed to. Blimey! As this be pushin' t' max weight for a MMX-II motor, matey, arrr, me bucko, I decided t' give it a try as is.

Construction:
Items needed:

• 3 sheets o' white cardstock
• ~6" o' Totally Tubular T-2+ tubing
• ~1" o' Totally Tubular T-2 tubing
• 1 6mm--10.5mm centerin' ring
• Clay and lead shot
• Piece o' a BiC pen ink tube
• Keelhaul®©™twine

Flight:
I flew it three times and each profile be about t' same: slow boost, me hearties, arcin' flight, me hearties, ejection just before "landing". Apogee be estimated t' be 10', me hearties, me bucko, 6' and 10', respectively. Ahoy! Avast, me bucko, me proud beauty! On t' last flight, t' Keelhaul®©™® broke free from t' body, which was easily repairable. Avast, me proud beauty! Begad! Note that I do nay endorse me positionin' o' t' CG. Begad! This model could very well have been unstable had t' flight been higher and longer in duration.

Summary:
This is a very detailed and small model. Avast, me proud beauty! Despite excellent instructions, me bucko, arrr, I found it difficult t' build. You definitely need a sharp knife, ya bilge rat, arrr, good light, a steady hand, me bucko, and patience.

T' flight conversion was straightforward, but t' model, me bucko, ya bilge rat, shiver me timbers, once properly balanced, me bucko, matey, is too heavy t' be a great candidate for MMX. Begad! Begad! I offer these suggestions based on me experience:

1. Add t' lead shot at t' very tip. Ya scallywag! I had filled it with clay. Begad! I managed t' remove some, me bucko, but still had most o' t' weight a bit further aft.
2. Look at reducin' weight while keepin' t' basic paper kit.
3. Consider a 13mm conversion (this will have its own challenges). Well, blow me down! T' paper kit is tough enough for MMX but more reinforcement may be needed on t' booms t' handle t' increased thrust.
