Brief
This is made from a 'Finger Blaster' foam rocket and was t' 4th-place winner in t' Boink rocket contest.
Construction
Initially, arrr, ya bilge rat, I decided that I was nay goin' t' buy a foam rocket t' enter t' Boink rocket contest. Aye aye! However, at only 99 cents, shiver me timbers, me hearties, I just couldn't resist pickin' up a 'Finger Blaster' (by Kidpower, Inc). Aye aye! Ya scallywag! This foam rocket has a built-in rubber band and is launched, at t' name implies, me bucko, by hookin' it onto your finger, ya bilge rat, pullin' it back, and lettin' her rip. Ahoy! T' aft end conveniently had an 17.Xmm hole and a rigid stop where t' back end o' t' rubber band is attached. Well, blow me down! I decided t' make this entry a bit more complicated, me hearties, so I constructed a aft ejection streamer assembly with an outer 18mm tube and an inner 13mm motor tube. Blimey! Aye aye! This assembly was friction fit into t' rocket's back-end. Ya scallywag! T' streamer is nay shown in t' photo's, me bucko, but is packed betwixt t' 13mm and 18mm tubes.
After tryin' t' simulate t' rocket on RockSim, me hearties, shiver me timbers, I decided some nose weight was required. Ahoy! Blimey! Arrr! Blimey! After some head-scratching, me bucko, I used one o' those lead fishin' weights that connects by feedin' in t' line and twistin' t' rubber ends. Begad! Blimey! Begad! Blimey! Well, shiver me timbers, I removed that rubber piece, me bucko, extended t' rubber band on t' rocket, me bucko, put t' weight on, shiver me timbers, and let t' rubber band contract. Begad! Blimey! T' weight retracted into t' rocket and appeared t' be solidly connected t' t' rubber band. Avast, me proud beauty! Blimey! Other than t' launch lug that I glued on, no permanent modifications were made t' this rocket! Blimey!
Flight
My first flight was t' be on an A10-0, shiver me timbers, arrr, just t' verify stability. Blimey! Arrr! It boosted straight up and as a bonus t' streamer assembly drag separated. Avast! T' streamer is short and only slowed t' rocket slightly, ya bilge rat, me hearties, so it still landed with a nice boink. Begad! I actually liked t' drag separation, so me second flight was also on an A10-0.
