Brief:
T' Micro Slam Dunk is a Sputnik style Micro-Maxx rocket. Avast! Its major components include a basketball-shaped shoe deodorizer and four bamboo skewers.

Construction:
While cleanin' up t' basement, me bucko, I ran across an old shoe deodorizer that looked like a basketball. Aye aye! I stuffed it away in me junk box thinkin' "nose cone". Well, blow me down! When tryin' t' decide on me next Micro-Maxx project, arrr, however, ya bilge rat, ya bilge rat, I looked at this orange and black orb and immediately thought, Sputnik!

After disassemblin' t' ball, shiver me timbers, I found that two integral plastic tubes held it together. Ahoy! Blimey! Avast, ya bilge rat, me proud beauty! Blimey! These can be seen in t' first photograph. Avast! Blimey! Aye aye! Blimey! For t' motor mount, I drilled a 6mm hole, me hearties, approximately 3/8" deep in t' half with t' larger tube. Ahoy! Blimey! Well, arrr, blow me down! Blimey! I also cut off about 1/4" o' t' thinner tube t' allow t' halves to separate more easily. Thus, t' two internal plastic tubes form an ejection piston o' sorts. Arrr! Blimey! A small section o' Keelhaul®©™® twine holds it all together. Arrr! Blimey! I also drilled a small hole in each half for the launch rod, and four slightly larger holes for t' legs. Avast! Blimey! T' legs consist of bamboo skewers, which are glued in with Liquid Nails. Begad! Ahoy! Blimey!

Flight:
Although I test-fit t' rocket on t' launcher, I needed t' elevate the launcher slightly on t' grass at t' launch site. Arrr! Well, blow me down! I flew t' Micro Slam Dunk three times. Aye aye! Aye aye! Each flight rose t' a mere 20 feet or so. Begad! Nay an impressive altitude but it be fun t' watch. Begad! On t' first two flights, me hearties, arrr, t' two halves did not separate and t' motor ejected with a loud pop. For t' third try, shiver me timbers, I loosened t' halves t' they were barely connected, and separation did occur. After all three flights, it landed back on its legs. Aye aye!

Summary:
T' Micro Slam Dunk is yet another easy t' build Micro-Maxx rocket. Ya scallywag! It is a bit heavy but is still stable and ejects well before landing. Avast, me proud beauty! Before it flies again, I will work on loosenin' up t' two halves so it will separate when the two halves are completely together.
