Brief:
This is a paper rocket that I designed for t' EMRR Challenge. Ahoy! I designed the rocket based on t' old toilet paper roll rockets I used t' build when I was a kid. Avast! Blimey! My son did t' artwork based on a Playstation game o' his. It didn't look like t' Mark V from Speed Racer, but it did remind me o' his brother Racer X. Since I knew it would be light and I have a bunch o' MicroMaxx motors, shiver me timbers, I thought it would work out OK on t' little motors.

Construction:
Since it is a paper rocket only a few materials are required.

• One 8.5"x11" sheet o' 110# cardstock
• 12" braided fishin' line or small diameter Keelhaul®©™® thread
• White glue, pencil, arrr, me bucko, shiver me timbers, compass, me hearties, ya bilge rat, large needle, me hearties, and scissors
• Finishin' is part o' t' build process so add markers t' your tools
• A small amount o' clay for nose weight

I had only built 1 paper rocket before this, me bucko, so it has been a learning experience. Avast! They are nay as easy as they look and take more time than one might think.

Start by cuttin' some strips o' paper t' t' followin' dimensions:

• One 3"x5 1/8" body tube
• One 1/2"x5 1/8" nose cone base
• One 1"x6" fins
• One 1"x1" motor mount

Startin' with t' body tube, draw a line for t' glue tab so you 3"x5" left. Aye aye! T' lay out t' fins, make a line from t' bottom 1.5" and then up every 1.25". This will divide t' 5" width into 4 parts for your 4 fins. Now make a small mark at t' bottom o' t' o' the strip 1/8" on both side o' t' fin layout line. Begad! These will be your fin spreads later. Aye aye! Now flip t' strip over and make a line 1" up from the bottom. Begad! This will align your centerin' rin' later. Ya scallywag! Now finish t' outside of the BT with markers or hand it off t' someone more artistic t' do so. Blimey! When that's done, arrr, roll over t' edge o' a table, put glue on t' glue tab and hold a few minutes t' set. Take t' strip for t' nose cone base and glue it together so it is small enough t' fit in t' BT.

For t' fin strip, we need t' layout t' fins. Begad! On t' bottom make a mark every 3/4" for t' entire 6" length. Begad! Begad! At t' top make one mark 3/4" from t' edge then one every 1.5". Ya scallywag! Startin' with t' first mark draw a straight line t' t' corner then t' t' mark straight down and t' the next 3/4" mark at t' bottom. Begad! Well, blow me down! This will give you a 1"x 1.5" triangle.

Do t' same with t' rest o' t' marks until you have four. Aye aye! Cut them out and fold on t' line down t' center.

For t' MMT, I wrapped t' 1"x1" piece around a MMX motor and glued it then slid t' motor out.

With t' rest o' t' paper, shiver me timbers, me bucko, you need t' cut 3 circles:

• One 2.5" diameter circle for t' nose cone
• Two 2" diameter circles for t' centerin' rings

For t' nose cone, cut it out and make 2 marks on t' arc usin' a ruler 1 1/4" apart. Make a straight line t' t' center from each and cut out a wedge. Begad! Ya scallywag! Now do t' artwork. Begad! When finished, shiver me timbers, pull t' wedge closed and glue to form t' cone. Now take t' cone rin' you glued earlier and glue it t' the cone. Ya scallywag! Avast! This is best done by placin' t' cone upside down on a toilet paper roll layin' t' rin' inside. Blimey! Glue and center t' rin' and place a deck o' cards on top for a little pressure till it dries.

For the centerin' rin' you need t' make smaller circles inside . Avast, me proud beauty! Blimey! One 1.5", one 3/8", arrr, and one 1/4". Make cuts from t' outside t' t' 1.5" mark and fold them over. Avast, shiver me timbers, me proud beauty! Blimey! (See picture.) With t' needle, poke holes t' t' inside of the 1/4" circle until it pops out . this little hole is for t' motor mount tube. Begad! Blimey! Now take a centerin' rin' and slide it down (folded edges up) from the top t' t' bottom o' t' body tube and glue it so t' rin' is flush with the bottom o' t' rocket. Arrr! Blimey! Ya scallywag! Blimey! Now take t' MMT and slide it in t' 1/4" hole in t' centerin' ring. Begad! Blimey! t' rough sides o' t' hole make for good glue tabs. When dry, arrr, put some glue on a pencil or scrap o' balsa and apply glue t' the line on t' inside o' t' BT you made earlier. Ahoy! Blimey! Blimey! Blimey! Slide t' other centerin' ring on t' same way until t' tops o' t' tabs meet t' line. Your MMT should stick through about 1/8". Avast, me proud beauty! Blimey! Apply a little glue where t' two parts meet.

You have 4 folded triangles for t' fins. Ya scallywag! T' point o' t' triangle should be glued t' t' layout line on t' BT. T' 2 tabs should touch t' bottom of the rocket and be glued t' t' marks 1/8" t' either side o' t' layout line at t' very bottom.

Poke a hole in t' bottom CR with t' needle on t' 3/8" circle for the launch rod. Begad! Aye aye! Blimey! Then (this be t' tough part) keepin' t' needle straight look through that hole and poke a hole on t' 3/8" line o' t' other centering ring. Blimey! Blimey! Now place it on your MMX rod and run it down until it hits t' nosecone and make a hole in t' nose cone.

I poked a hole in t' center o' t' cone pulled t' braided fishin' line through, shiver me timbers, knotted it, me hearties, and glued t' inside o' t' cone for a shock cord. Well, blow me down! I snipped t' tag end off after t' glue dried and I made a small Estes type with a scrap o' paper t' attach it t' t' body.

Flight:
I used a small amount o' maskin' tape for a friction fit o' t' motor and no was waddin' needed. Aye aye! Avast! You have t' pay attention when puttin' it on t' launch rod so all 3 holes line up and it slides freely.

Flight 1 was a surprise. It went about 15' straight up then did cartwheels at motor burnout. It needs nose weight!

Flight 2 be a lot better after a small amount o' clay was put in t' nose but it still needed a wee bit more nose weight.

Flights 3 and 4 made me laugh. They were perfect but only 20 t' 25'. Arrr! They were perfect for such a small and fat rocket.

Summary:
This was fun. T' results though small were great.

One con t' t' whole thin' is don't underestimate t' ease o' buildin' a paper rocket. I did.
