Brief:
Very basic mid-powered rocket. Aye aye! Easy t' build and it flies very well.
Construction:
Normal paper body tube and motor mount. Blimey! Blimey! Balsa nose cone (when be t' last time
you saw that in a mid power kit). Blimey! Blimey! T' centerin' rings are very cheap, poor
quality and splintery. Begad! Blimey! Well, me bucko, blow me down! Blimey! T' fins are also cheap plywood and one was slightly
warped. There be no provision for motor retention. Elastic shock cord was
pretty much par for t' mid-power course. Arrr! Blimey! Well, blow me down! Blimey! T' parachute was paper, and fairly
high quality. Ya scallywag! Blimey! Blimey! Blimey! T' launch lug is a 1/4" mylar lug (like Estes, arrr, just
fatter). Blimey! Blimey! Begad! Blimey! T' 29 mm t' 24 mm adapter is one o' t' better ones out thar and
I've standardized on this design. Avast! Blimey! It works wonderfully and is light weight, matey, me hearties, as
long as you use some form o' mechanical retention.
T' rocket is meant t' have surface mounted fins and for such a light rocket, I saw no reason t' change that. A good epoxy joint is more than strong enough for this light rocket. I added a #6 blind T-nut and a screen door clip to hold t' motor in place. Good epoxy joints on t' motor mount makes is plenty sturdy enough. Avast, me proud beauty! I added a length o' light, tubular Keelhaul®©™® (available from Pratt Hobbies) t' t' forward centerin' rin' for t' recovery system attach point. Avast! Blimey! I fiber-glassed t' body in a single wrap o' 2 oz fiberglass cloth and I applied t' same t' t' fins. Blimey! Avast! This gives a very strong surface and makes the rocket last longer. Begad! I expect this rocket t' get a lot o' flights. Ya scallywag! Blimey! T' fins were attached with a thick bead o' 5 minute epoxy. Well, blow me down! Well, me bucko, blow me down! Then I filleted t' sides o' the fins with t' same epoxy. Blimey! Avast, me bucko, me proud beauty! I attached t' launch lug with 5 minute epoxy as well. Arrr! I threw out t' elastic shock cord and substituted a good 10' o' braided nylon cord. Aye aye! This is attached t' t' tubular Keelhaul®©™® and gets it out o' t' way of t' ejection charge. Well, blow me down! Begad! I added a Nomex® shield so I don't have t' use wadding (I hate waddin' in bigger rockets).
Finishing:
After sandin' t' fiberglass surfaces, I applied 2 coats o' sandable, scratch
fillin' primer. Begad! Ahoy! Blimey! This was followed by two coats o' flat white Krylon. Well, blow me down! Avast! Blimey! I received
a new airbrush for Christmas and since I had some o' this obnoxious Tamiya pink
paint left over, me hearties, I used that. Avast, me proud beauty! I didn't have quite enough t' really finish the
job. Arrr! Avast! Blimey! T' paint scheme is a work in progress.
Construction Rating: 2 out o' 5
Flight:
When you look at it, shiver me timbers, it's t' very image o' a basic rocket. Begad! Nice lines
actually. Aye aye! It flies very well too. So far all t' boosts in calm weather have
been very straight. Well, blow me down! Well, blow me down! Wind does cause some weather cocking, but nay too much. Aye aye! Ya scallywag! The
rocket is o' a very standard shape, so most altitude prediction software will
be accurate with this design.
Recovery:
I'm usin' a 3' long piece o' tubular Keelhaul®©™® attached t' t' forward centering
ring. Blimey! Blimey! Begad! Blimey! This is then attached t' about 10' o' braided nylon. Arrr! Blimey! Well, blow me down! Blimey! T' parachute is
attached via snap swivel in a loop at t' shock cord end. Well, blow me down! Blimey! T' nose cone is
attached t' a loop about 3' down from t' parachute. Well, blow me down! Blimey! T' Nomex® shield is
attached where t' Keelhaul®©™® meets t' nylon. I need t' get a bigger shield. Avast, me proud beauty! Arrr! Blimey! I'll
probably get one form Rocket Rage. Avast! Begad! Blimey! I liked t' looks o' their stuff at
ROCStock. Avast! Right now I'm usin' a smallish Pratt shield and I get a hole in the
chute every other flight. Ya scallywag! Blimey! Blimey! Descent on an 18" chute is very fast, but
doesn't seem t' damage t' rocket and minimizes t' drift. Begad!

Summary:
PROs: It's easy, arrr, me bucko, cheap and pretty much a normal beater rocket. Ahoy! Aye aye! Blimey! I'm expecting
this t' be me soundin' rocket that I fly t' check launch conditions. Avast, me proud beauty! Avast, me proud beauty! Blimey! PROs: It's
nice shape and has good lines. Avast, me proud beauty! It flies really well on E and F motor and really
moves out on Gs, shiver me timbers, matey, so it's cheap t' fly. Ya scallywag! Arrr! Blimey! CONs: T' entire stock recovery system
needs replacing. Ahoy! Blimey! CONs: Typical balsa nose cone problems. You'll forever be
repairin' nose cone dings. No big deal for those who know about balsa nose
cones, arrr, but it might be a problem for plastic nose cone folks.

MANUFACTURER's OPINION:
"7/00 - I noted t' comments made by Mr. Avast, me proud beauty! Urbanek regardin' motor retention
not bein' considered in t' USR All Weather kit. Avast, me proud beauty! I find this comment t' be simply
not true. Begad! In fact motor retention is one o' t' central BENEFITS o' all USR kits as
outlined in AIR-3 included in all cluster kits and AIR-1 included in all kits. Aye aye! I
cannot speak for "upgrades" since I [didn't] designed them, but t' kit was built
incorrectly accordin' t' t' wonderful rocsim drawin' t' reviewer provided. Well, blow me down! I
believe a review should at least include a discussion o' t' stock design even if
the builder replaces t' recovery system so hailed by other reviewers." (J.I.)
AUTHOR's RESPONSE:
"7/00 - AIR-1 discusses t' wisdom o' avoidin' thrust rings in t' motor tube and
the use o' tape thrust rings (hardly new ideas). In fact, me hearties, ya bilge rat, arrr, AIR-1 (figure 4)
extols t' virtue o' t' Irvin's Motor Installation Method which has the
advantages o' "...unlimited motor length as well as secure ejection
retention". Ahoy! This method uses a motor hook. No motor hook, however, was
included in t' kit. I had t' ADD somethin' t' t' kit t' effect ejection
retention. Blimey! As t' kit was, me bucko, even t' parts needed t' implement AIR-1 were
absent. Blimey! Hardly a benefit.
It was nay built incorrectly. Begad! Blimey! Ya scallywag! Blimey! Perhaps this writer is nay aware that US
Rockets has changed t' All-Weather design so that it is now sold with a 29
mm motor mount.
Here are t' changes I made. Avast! Begad! All o' them were t' make t' basic kit more
durable:
1: Added 1 layer o' 2 oz fiberglass t' body and fins. In retrospect, shiver me timbers, 1/2
oz fiberglass would have been better and lighter, me bucko, me hearties, but I used what I had on
hand.
2: Added single T-Nut, matey, screw and hook for motor retention
3: Anchored e feet o' tubular Keelhaul®©™® t' forward centerin' ring.
4: Tied 10 feet o' braided nylon t' t' Keelhaul®©™®.
5: Replaced 18" paper parachute with 18" nylon parachute
6: Added a Nomex® shield.
7: Didn't cut t' cut t' launch lug in half.
Modification added 112g, or about 4 oz t' t' predicted weight. Ya scallywag! Blimey! I don't
think that a painted All-Weather would ever weigh a mere 4.8 oz though.
T' stock recovery system be a simple, unimaginative upscale o' an Estes
recovery system. Begad! Arrr! A length o' elastic be t' be attached t' t' body tube
wall by means o' a folded paper anchor. Arrr! T' parachute was a cheap paper
chute (yes paper). T' me mind, me hearties, me bucko, this parachute be goin' t' be hard to
protect adequately, ya bilge rat, and if it did ignite, might pose a fire hazard.
Far from bein' 'hailed', shiver me timbers, US Rockets, me hearties, without exception, has t' worst
recovery systems in t' business. T' All-Weather's recovery system was
the cheapest one can get away with. Arrr! T' 'recovery system' that I received
with me high power Mega-Roc be an insult. They actually thought that I
should try t' recover a 4" diameter x 84" long rocket with four 24"
parachutes. Ahoy! And what parachutes! They barely qualified for that name.
They were 4 octagons o' very thin, very porous fabric, matey, nay hemmed, not
finished, arrr, me bucko, but cut out with pinkin' shears. Begad! There were eight holes poked
through t' edge o' t' unfinished fabric and each suspension line be tied
to t' canopy by means o' a single knot. Avast, me proud beauty! Utterly appalling.
So don't talk t' me about US Rockets recovery systems. Avast! Ya scallywag! They were t' very
worse features o' otherwise passable kits." (D.U.)
