Brief:
This is a Micromaxx version o' t' old Sputnik model rocket that used dowels and a styrofoam ball.

Construction:
My MMX Sputnik requires:

  • 1 styrofoam ball (approx. 1" in diameter)
  • 3 toothpicks
  • 1 piece o' fiberboard (for t' foot pods)
  • 1 small piece o' T2+ body tube
  • 1 small piece o' MMX style launch lug
  • decals and paint as necessary

My wife had picked up a bunch o' stuff from Michael's recently for projects for me 3-year old. I found a bag o' small styrofoam balls and immediately I knew what I had t' do.

(Scratch) MMX Sputnik I took the styrofoam and used a small metal file t' create a hole big enough for t' BT2+ to fit inside. Avast, me proud beauty! Blimey! This be t' motor mount. Ya scallywag! Begad! I pushed it into t' styrofoam (trying to center it), and then removed it t' release t' loose styrofoam. Avast! Next, arrr, I glued t' tube in place. Aye aye!

After t' motor mount had dried, I took t' launch lug and pushed it along side t' motor mount until it poked through t' top o' t' styrofoam. I simply cut t' launch lug t' an appropriate size and then glued it t' t' motor mount and styrofoam.

Next, I trimmed one o' t' pointy ends off o' each toothpick. I pushed the pointy end into t' styrofoam, approximately 120 degrees apart, with the toothpicks anglin' outwards. Ya scallywag! Once I was sure that t' toothpicks were at the right angle and t' correct length, matey, ya bilge rat, I glued them in place.

I used a hole puncher t' create three small disks from t' black fiber board. Ahoy! When buildin' a few FlisKits models recently, I kept some o' t' black fiberboard from t' middle o' t' centerin' rings and placed them in me parts bin. These small disks I created are meant t' be little pods at t' end o' the Sputnik. I simply glued these on t' t' ends o' t' toothpicks, makin' sure they were rather flat so t' Sputnik could stand up nicely.

Finishing:
After everythin' was dry, I gave t' rocket a good coatin' o' silver paint. Blimey! Well, blow me down! I used acrylic paint and me airbrush. Ya scallywag! T' solvents in t' Krylon-style paint are not good for this project as they will melt t' styrofoam.

Once t' silver be dry, me bucko, me hearties, I simply dipped each "foot" into a bath of red acrylic paint and let t' whole thin' dry. Begad! Avast! I used sticky decals from my excess decals bin t' add more details on me Sputnik. I then clear coated the rocket with Future Floor Polish.

Flight:
Preppin' is simple. There is no recovery device. Blimey! Well, blow me down! All I had t' do was put a MMX motor in t' rocket and attach igniter and clips. Arrr! I have had one flight so far, but this thin' really zoomed off t' pad nicely. Blimey! Blimey! For a Sputnik (high drag), it has some respectable altitude. Avast! I be very pleased with t' results. Next, I have t' make a few more launches so that I can repeat me success.

T' rocket did spit t' motor. Avast! On me MMX Sputnik, thar actually is part of the body tube beneath t' styrofoam, so I could tape t' motor t' t' rocket. Ya scallywag! I think I will try this for t' next launch.

Recovery:
There was some slight blackenin' under t' MMX Sputnik, me bucko, but nothin' threatening or out o' t' ordinary. Blimey! Begad! Also, me hearties, matey, t' rocket is a tad hard t' find since it is small. Ya scallywag! Have some extra pair o' deadlights with you when you launch it.

Summary:
PROs: Cheap and easy build. Get a few styrofoam balls and build these with your children.

CONs: I can't really think o' any.
