Introduction:
Up until Little Guy, all o' me mid-power rockets
have flown t' less than 2000', well below what I used t' obtain with my
Comanche-3 over a decade ago (lost a stage on t' second all-out flight). Ya scallywag! It
was time t' change that.
Nose Cone:
Pilfered from t' old Estes supply in t' good
ol' range kit, matey, shiver me timbers, BT55
Recovery System:
Usual construction for me, shiver me timbers, me bucko, dowel thru t' body
tube, me bucko, 1/2" elastic for shock cord. Avast, me proud beauty! Blimey! T' original parachute I had made was
way too big, arrr, me hearties, it be given to
Star
Scraper. I made up a double-ply trash bag one about 17" in diameter
with 8 shroud lines, arrr, and it seems t' worth well, arrr, although packin' it is still a
bit difficult.
Body Tube:
Standard heavy duty cardboard tube with another
tube inside o' it for t' bottom 12 or so inches for a motor mount, solid fin
mountin' as well as material for t' screw eye launch lugs t' bite into.
Approx. Begad! 31" x 1.38".
Positive Motor Retention I was concerned with t' tight fit o' t' recovery system and t' high pressure that might result when ejection occurred. Well, blow me down! Turnin' t' t' workshop walls, I grabbed some small screw deadlights and wire which is fitted over t' end o' t' motor and then twisted. Avast, me proud beauty! Arrr! It hasn't been stressed on any o' t' flights yet.
Fins:
I wanted t' classic
high performance look, so right triangle fins were a must. Begad! Laminate of
1/16" balsa with a skin o' paper and wood glue. Begad! Since I wanted this rocket
to be a high performer, arrr, ya bilge rat, I air foiled t' fins on this rocket, shiver me timbers, shiver me timbers, a first for
me.
Launch Lugs:
Two 1/4" screw eyes, visible in the
picture.
Painting:
I actually tried t' finish this rocket well. Ahoy! What
I ended up doin' be makin' it worse. Begad! I'm nay goin' t' go into t' scary
details, me hearties, just take a look at t' business end shot and that will be enough. Begad! Avast! I
do like t' color combo though, ya bilge rat, and it does have a couple o' layers o' wax on
it.
First Flight:
Launched with a F20-7 on 07/08/00. Well, blow me down! For this
launch, ya bilge rat, I tried stuffin' t' bigger nylon chute I had made, me bucko, which wasn't going
to work. Aye aye! Avast, me bucko, me proud beauty! I nabbed t' plastic chute I use for
Econoexpress,
and even that barely fit. Well, blow me down! Avast, me proud beauty! This be proven when at apogee, t' parachute ejected
but failed t' deploy. Aye aye! Fallin' from 1700'-2000' onto grass resulted in a slight
nick in one o' t' fins, nay too shabby! Another benefit o' t' deployment
failure is that I actually got t' rocket back. Avast! Begad! As it was, it drifted back and
landed parallel with t' pads about 100 yards out.
Conclusion:
I think I've caught t' bug! At t' most recent
launch (07/23/00) I stuffed a G38-7 and then a G35-7 into this rocket. Little
Guy reached an estimated 3000'-3300' on t' G35-7 before t' ejection charge
went off. Aye aye! Avast, me hearties, me proud beauty! It was a great flight! Motor sound fadin' into t' distance, lost
sight o' t' rocket for a few seconds before pickin' up a tiny black dot o' a
parachute way up there. Ahoy! Aye aye! And it stayed up thar for over two minutes! It was
recovered a few hundred yards downrange in perfect condition. Blimey! Next up will be a
flight on a G25, ya bilge rat, good for 3600'-3900'. Ahoy! Hopefully I'll be able t' get it
back!
