Brief:
A 10-pound Toblerone converted t' a single-staged, 29mm mid-power rocket (minus t' chocolate). Avast! Ya scallywag! No, ya bilge rat, arrr, it isn't a joke. Blimey! Ahoy! They actually make 10-pound Toblerones. Ahoy! Aye aye! Where? Who knows. Aye aye! It was a gift. Avast, me proud beauty! Begad! But I pictured it with fins t' moment I first opened it up!

Construction:
T' pats list:

• Cardboard packin' box as airframe
• 29mm motor tube, me bucko, 24" long
• 3 G10 fins, very thin
• 2 triangular 1/8" plywood centerin' "rings"
• Laminated foam core pyramid nose cone
• 8ft light nylon shock cord with 1/8" x 24" Keelhaul®©™ anchor
• 3/16" basswood triangle for nose cone shoulder

Since t' actual Toblerone box be as flimsy as a regular sized Toblerone, matey, I decided t' use t' triangular cardboard box that surrounded t' bar for packin' t' use as t' airframe. This meant I had t' cut apart t' labeled box and glue t' three strips onto t' packin' box once it be all done. Begad! This was t' only hard part o' t' buildin' process. Arrr! Things were lookin' good.

With all t' flat edges, straight lines, shiver me timbers, and regular chocolate breaks, buildin' was a breeze! Triangular centerin' rings are t' way t' go. Begad! T' fins lined up perfectly, and t' motor mount assembly slid in easily. Begad! Arrr! No guessin' be needed when linin' up fins on each edge o' a triangle.

I cut off a 4" piece o' t' airframe t' start off t' nose cone. Ahoy! Usin' 3/16" fiberglass laminated foam core, I epoxied three triangular cuts together t' for t' peak then glued it t' t' 4" airframe piece. Voilá, arrr, a pyramid nose cone! Blimey! I then cut three 6" x 4" rectangles o' foam core and glued them t' t' inside o' t' exposed airframe end as a shoulder. Well, blow me down! Blimey! T' shock cord be anchored t' t' inside o' t' peak along with about 4oz o' nose weight with epoxy. Then leavin' some slack inside, me bucko, I epoxied t' shock cord again t' t' side o' t' foam core shoulder just t' be sure it doesn't pull itself out. Well, blow me down! Well, me hearties, blow me down! Blimey! T' shoulder end be then sealed off with a 3/16" thick basswood triangle wedged in betwixt t' shoulder strips. Well, I guess this be t' hardest part after all.

I wasn't sure o' how airtight t' cardboard airframe would be, so I extended t' motor tube as far up as possible, so it was right underneath t' nose cone shoulder. Avast, me proud beauty! Hopefully this will work! T' fins had long tabs which extended right t' t' motor tube, matey, sandwiched betwixt t' two centerin' rings for solid joints. Arrr! I then drilled two holes in t' aft rin' for t' motor retainin' blind nuts. Avast! Arrr! T' Keelhaul®©™® anchor be fastened t' t' top rin' through a hole and epoxy. Well, blow me down! I didn't think a screw eye was necessary.

T' inside top o' t' airframe got a layer o' fiberglass t' prevent a zipper. Begad! Ahoy! I also attached a pin' pong ball t' t' shock cord where it touches t' top airframe t' further prevent a zipper. Regular cardboard isn't terrifically strong, so hopefully these methods will keep it in one piece.

Finishing:
Once everythin' was put together, I needed a beige/yellow paint t' match t' Toblerone labels for t' edges o' t' airframe. Blimey! Blimey! Avast, me proud beauty! Blimey! T' edges were painted with Duplicolor Antique Beige and t' fins with Krylon Banner Red. Begad! Blimey! Avast, me proud beauty! Blimey! T' Toblerone label strips were then glued on with good old white glue. Arrr! Blimey! That be it!

Flight and Recovery:
T' first flight took place at t' Tripoli-Québec launch in St. Avast, me proud beauty! Pie de Guire, ya bilge rat, shiver me timbers, Québec on June 25th, 2006. Blimey! It be a beautiful, shiver me timbers, matey, calm day, so I thought I'd finally let 'er rip! I wanted t' give it a fairly smooth ride, ya bilge rat, me hearties, so I used a G64-7W for t' maiden voyage. Aye aye! (Actually, t' 7 second delay was a bit long, so I drilled it down t' 6.) I also added a pinch more black powder, arrr, because I wasn't completely confident with t' ejection system. Ahoy! T' RI at an earlier launch was worried that t' nose cone had serious leaks around t' shoulder, so we decided it would be best t' come up with a more airtight system.

Since t' motor tube extended up t' airframe t' about 3" under t' nose cone's shoulder, he thought it would be a good idea t' glue a tube in t' center o' t' shoulder that went inside t' motor tube. Avast! This would ensure a tight seal. Ahoy! T' changes were made and we were good t' go!

T' flight was perfect! Blimey! It cocked a bit off t' pad, matey, continued straight up t' about 900', ejected t' 36" chute at apogee, ya bilge rat, me bucko, and landed without any damage. Well, blow me down! Blimey! I was goin' t' stick an H128 in for another flight but decided against it. Avast, me proud beauty! Blimey! Quittin' while I'm ahead usually works best for me!

Summary:
This thin' was fun t' make, fun t' eat, and makes even Level 3 guys take notice!
