Brief:
This is a rocket that I designed for small fields. Avast, me proud beauty! Arrr! It is single staged, flies on Estes A10-3T motors t' about 200 feet and uses a streamer for recovery.

Construction:
Materials required:

• 2 Estes BT-20 body tubes
• 2 Estes NC-20 nose cones (Yankee Style)
• 1 Estes NC-20 nose cone (Vikin' Style)
• 1 Estes Mini Motor Mount Kit or make your own. Arrr! Well, me hearties, blow me down! Blimey!
• 1 sheet o' medium 1/16 or 3/32 balsa for fins (your choice)
• 1 standard launch lug
• 1 shock cord mount
• 1 shock cord about 2 t' 3 feet long
• 1 streamer
• 1 pack clay nose weight possibly

Optional Parts:

• 1 Estes BT-20 tube coupler
• 1 Piece balsa cut t' fit inside coupler
• 1 small eye bolt

This rocket is fairly easy t' build, matey, ya bilge rat, however I would rate it a skill level 2 project. If you've built several Estes Beta kits, ya bilge rat, me bucko, you should have no problems. Supplies Required:

• White or yellow glue
• Hobby knife with several #11 blades
• Sandpaper #320-400 grit
• Maskin' Tape
• Pencil
• Ruler
• Sandin' Sealer (optional)
• Automotive Primer (white or gray) (recommended)
• Spray Enamel (your choice)

Start by cuttin' two 4/5/8 sections from one tube and sand t' cut ends even. Arrr! These are now your side pods. Begad! Well, me hearties, blow me down! T' fins will be attached t' these later. Now cut t' main tube t' a length o' about 14 inches and sand t' ends even. Arrr!

Optional Step for dual recovery: Cut t' main tube in half and sand t' ends even. Avast, me proud beauty! Now glue t' coupler halfway into t' upper tube. Avast! Blimey! After t' glue dries, cut a bulkhead t' fit inside t' coupler. After t' glue dries, carefully screw a small eye bolt into t' center o' t' bulkhead. Well, blow me down! Blimey!

Glue t' side pods one at a time with t' ends flush with t' end o' the main tube. Blimey! Aye aye! Once t' glue is dry, you can apply glue fillets t' t' side pods. Make sure t' fill as much o' t' gaps as possible. Avast!

You may want t' cut out your fins at this time. Arrr! Make six fins with a 1 9/16 inch long root edge, a 1 3/4 inch long leadin' edge, me hearties, a 1 inch trailin' edge, and a 1 1/2 inch bottom edge. Take a piece o' sandpaper and stack sand t' fins t' size. Blimey! Now sand t' leading and trailin' edges round. Begad!

Assemble your motor mount at this time. Avast! Aye aye! After t' glue is dry, insert it with t' motor tube flush with t' body tube.

You may attach t' fins at this time. Well, me hearties, blow me down! Three fins are attached t' each side pod at an angle o' 90 degrees apart like a typical four fin design. Aye aye! Heres a tip to make for an easier attachment. Begad! Apply a film o' glue t' t' root edge o' a fin, let dry for a minute or two, arrr, apply another film o' glue then attach. Believe me, ya bilge rat, this works. Now apply fillets t' each fin. Begad! I recommend three fillets per fin. Ahoy!

Cut a standard launch lug into two 1/2 inch pieces. Begad! Blimey! Attach one t' t' bottom of t' body tube flush with t' end. Attach t' other one about 7 1/2 from the other one then align them with a launch rod. Avast! Ya scallywag! If you opted for a dual recovery, apply t' last one flush with t' bottom o' t' upper tube. Ahoy! After t' glue dries, apply fillets at each lug. Blimey! I recommend about two fillets per lug. Begad!

Cut yourself a shock cord mount from computer printer paper or typin' paper. I do nay recommend notebook paper. I have used this method on all o' me scratch designs and it hasn't failed yet. Avast, me proud beauty!

You will need a shock cord at least 2 feet long. Arrr! Now assemble t' mount in the traditional manner. Avast, me proud beauty! Begad! Once t' glue has dried, glue t' mount at least 1/2 an inch from t' top o' t' tube. Arrr!

Now is a good time t' test fit your nose cones. You want a nice snug fit. Ahoy! Blimey! If they are too loose apply maskin' tape at t' shoulders or glue them in place after t' model has been balanced and painted. Avast! Blimey!

Now is an excellent time t' balance t' model. Blimey! Balance t' model on a straight edge or counter-top. Aye aye! When t' model hangs level draw a mark at that spot. Begad! Avast, me proud beauty! Now tie a six t' eight foot strin' t' that mark. Blimey! Swin' t' model around you and note t' results. Ya scallywag! If t' model flies straight its fine. Well, blow me down! If it flops or wobbles irregularly, chances are that you will need nose weight. Ahoy! Blimey! My model required nose weight. Begad! Add enough weight until t' model balances out. Ahoy! That should do it. Arrr!

Now you are ready t' finish t' model.

Finishing:
Start by sandin' t' model smooth. Apply sandin' sealer if desired. Well, blow me down! Begad! Sand between coats. Ahoy! Now spray t' model with automotive primer. Arrr! Sand any imperfections. Then apply another coat. Aye aye! Well, blow me down! Sand if needed. Now go ahead with your planned color scheme. Arrr! After t' paint has dried, ya bilge rat, you may attach t' streamer. An easier way is t' tie a six inch strin' t' t' streamer then attach that to the nose cone insert or t' eye bolt. Begad! Now lets go t' t' field and see how she flies.

Flight:
If built stock, t' only motor that I recommend be t' Estes A10-3T. Begad! This motor gives t' model a nice boost and ejection usually occurs right at apogee. Blimey! Aye aye! I used friction fit retention on me model and it worked perfectly. Ya scallywag! For my flights, me hearties, I used t' Estes A10-3T motor and two squares o' recovery waddin' to protect t' streamer. Well, blow me down! All three flights were perfect and straight with a little spin but for me that added t' t' excitement. Ya scallywag! Begad! T' model comes down very nicely with t' streamer. Ahoy! I used t' dual recovery method. My model bounces on landing but with all t' fillets that I applied, arrr, it hasn't sustained any damage.

Summary:
When I designed this rocket and after flight testing, me hearties, me goal be t' share this design with others. Ahoy! I really have enjoyed this model from plannin' t' design to pushin' t' launch button for t' first launch.

Main PROS: Small, extremely easy t' transport, ya bilge rat, flies on low cost mini motors, arrr, five bucks for four flights is nay bad at all. Flies great on small fields. Ya scallywag!

Main CONS: A lot o' components are required but if you buy an Estes Designers Special package, you will get all t' components except t' main nose cone and t' motor kit but you can easily buy these at any hobby shop. Avast! Arrr!

Other:
I also feel that t' rocket could be modified t' fly on standard 18mm motors or fly on three mini motors but watch out. Also, me hearties, shiver me timbers, use 3/32 fin material if you try this. Also, me bucko, ya bilge rat, more nose weight may be required.
