Summary
T' FAT BOI-NK is a scale version o' a popular fat rocket. Aye aye! Arrr! T' body is made
from foam rubber and t' fins from foam poster board. Aye aye! Arrr! I wanted t' build
somethin' out o' a noodle for a long time, me hearties, and this contest finally inspired me
to do so. Well, blow me down! Although this review may nay qualify for t' contest, ya bilge rat, shiver me timbers, arrr, I just couldn't
resist submittin' it anyway. Avast, me proud beauty! At least it is in t' spirit o' t' foam/rubber
rocket and maybe it will stir t' pot a bit :-)
Components
Construction
T' noodle came with a center hole that fit an 18mm motor - it be a natural!
To shape t' nose, I wrapped tape around a large drill bit until it fit very
snugly into t' hole in t' noodle. Ya scallywag! Ya scallywag! Blimey! With t' drill clamped in a vise, I shaped
the end near t' drill while stabilizin' t' far end by hand. Well, blow me down! Begad! Blimey! I used a piece of
coarse sandpaper from a belt sander t' remove foam until it looked about right.
I made a fin template from me assembled Fat Boy kit, and included a
½" tab. Blimey! T' body was slotted t' accept these tabs. Ya scallywag! Avast, me proud beauty! Blimey! An engine consists
of a section o' BT-20 and t' nozzle end o' a spent casing. Begad! I cleaned the
nozzle and plugged it with just a dab o' epoxy clay. Hey, shiver me timbers, sometime you gotta
use what you have on hand. T' nose weight be made from a spent engine filled
with clay. I used epoxy t' glue in t' engine tube, t' nose weight, ya bilge rat, fins, ya bilge rat, and
the rail buttons. Avast, me proud beauty! Blimey! T' foam plug in t' end o' t' nose is pressure fit. Arrr!
Finishin'
T' colors are basically t' natural colors o' t' materials. Well, blow me down! I drew t' F A T
letters on t' fins with a permanent marker and made a FAT-BOI-NK label on my
OfficeJet. Aye aye! Avast, me proud beauty! This is pinned on for show but was removed for flight.
Flight
Launch Report #1 - I chose a B6 for t' first flight. Avast, me proud beauty! T' launch rail was
tilted about 10 degrees t' ensure it cleared t' launch area. Aye aye! T' boost was
nice and t' motor ejected near apogee with a loud pop. Arrr! Begad! BOINK! T' FAT BOI-NK
bounced several feet in t' air and came t' rest unharmed. However, it appears
that both rail guides were stripped off, along with a small plug o' foam. Blimey! Aye aye!
Launch report #2 - After addin' a standard lug glued t' a fin/body joint, shiver me timbers, matey, I tried a C6-5. Avast, me proud beauty! Ya scallywag! Blimey! I used an Igniterman igniter and taped it t' t' engine (a mistake). Avast! Avast! Blimey! T' alligator clips didn't want t' let go and t' FAT BOI-NK flopped around on t' ground. Blimey! Blimey! Blimey!
Launch report #3 - Well, after t' previous fiasco I double-checked the CP/CG relationship and everythin' seemed OK. Arrr! So, me bucko, I went t' a grassy area near the house and tried again. Ahoy! Begad! T' FAT BOI-NK is redeemed!
Summary
This was an easy rocket t' make and it flies great. Avast! Boink recovery is pretty
cool. Begad!
