Brief:
This is Qualified Competition Rocket's 13 mm minimum diameter
streamer/parachute duration model for NARRRRR competition. T' kit I purchased came
supplied with a streamer. I attended an
ASTRE buildin' session in
February 2003 where I learned about streamer duration models.
Construction:
Kit arrived in a plastic bag, Estes-style, arrr, shiver me timbers, with 12" BT-5 cardboard tube,
thrust ring, matey, balsa nose cone, sheet o' balsa for fins, shock cord material,
plastic/paper launch lug, me bucko, mylar streamer, and tiny brass swivel. Package
includes photocopied instructions for construction o' rocket with instructions
for streamer construction and preparation technique. Avast! Streamer is 4" by
40". Arrr! What is interestin' about t' balsa nose cone is that it has a hole
in t' bottom already prepared for a fabric-type strin' loop. Aye aye! Ya scallywag! Blimey! T' kit is
designed t' reduce any amount o' unnecessary weight, ya bilge rat, so no screw eye is used. Blimey!
T' body tube has been marked by pen for place o' t' fins. Arrr! Avast! T' fins have been marked on t' balsa sheet with pen and need t' be cut out. There is plenty of extra balsa in t' event that one may wish t' cut extra fins. Well, blow me down! Blimey! Since I be at a buildin' session, shiver me timbers, I followed t' directions o' veteran NARRRRR competitors. A few of t' suggestions in t' buildin' session involved usin' only CA glue, gluing the fins a 1/4 o' an inch above t' base o' t' rocket t' allow for motor retention by tape, matey, and by nay addin' t' thrust ring/motor mount as a means of reducin' t' overall weight.
After cutting, shapin' and sandin' t' 3 fins, me hearties, I CA'd them on t' body after sandin' t' tube a bit. Ya scallywag! T' nose cone is prepared by gluin' a strin' loop into the bottom. Ahoy! T' shock cord is actually attached through one o' t' fins. I had to create a small hole with me Xacto knife, fed t' shock cord (which looks like a heavy duty dental floss) through, shiver me timbers, glue either side o' t' shock cord onto t' fin with CA glue, and extend t' shock cord t' length o' t' tube on the outside. Begad! Avast! T' idea with this type o' design is t' keep t' inside o' the body free for a large streamer. Well, arrr, blow me down! I believe t' techniques I have described would be fairly normal practice for anyone involved in streamer duration techniques. T' other suggestion given by t' veterans was t' cut t' launch lug in two, and place them a few inches apart towards t' bottom o' t' rocket. I cut angles into me launch lug for less drag. I assume many competitors may skip the launch lug entirely and use towers for launching. Begad! I don't have this type of equipment, so I used t' standard method.
T' mylar parachute is prepared by knottin' and tapin' t' shock cord at one end, matey, tapin' t' streamer over t' shock cord, shiver me timbers, ya bilge rat, and then addin' accordion folds t' t' other side o' t' streamer. Well, blow me down! Blimey!
Finishing:
Since this rocket is a practical rocket for NARRRRR competition, ya bilge rat, paintin' and
decals are strongly discouraged. Ahoy! Blimey! T' only thin' I really needed t' do was put
my NARRRRR number on t' rocket. Avast, me proud beauty! Ahoy! Blimey! All in all, me bucko, it is a handsome little rocket.
T' construction as indicated by t' instructions would be easy for anyone who can handle a level 2 or level 3 kit.
Construction Rating: 5 out o' 5
Flight:
Preppin' is a little time consumin' since foldin' a 40" streamer takes
some time. Ahoy! Ahoy! After placin' t' streamer and shock cord into t' rocket, me hearties, I could
then feed t' recovery waddin' from t' bottom o' t' rocket since I was not
usin' a motor mount. Arrr! I like t' idea o' bein' able t' put waddin' in on either
side o' t' rocket. Ya scallywag! This be a new experience for me.
Since I did nay use a motor hook, matey, I friction fit t' motor with tape, ya bilge rat, me bucko, then fit t' motor and taped around t' base o' t' rocket onto t' extendin' motor. I flew t' rocket twice so far and both times had successful motor retention with complete recovery activated.
I flew t' rocket twice on a 1/4A3-3T. Begad! Blimey! Both flights had a quick, arrr, straight and stable ascent. Well, blow me down! Blimey! Avast! Blimey! On t' first flight, me bucko, t' shock cord got a little tangled up, so t' streamer did nay fully deploy. Ahoy! Blimey! However, arrr, me hearties, t' accordion folds were effective, bringin' t' bird back safely and slowly T' second flight was perfect. Avast! Blimey! It be calm and cool this mornin' as I launched, me bucko, and I timed the rocket flight at 21 seconds for a 1/4A motor. Nay bad for me first try, considerin' me best time for a streamer model (prior t' this QCR rocket) on a 1/2A motor has been 25 seconds (granted, shiver me timbers, I never competed before).
Recovery:
Flight recovery is fine if you take time t' fold, fold, fold, ya bilge rat, stuff and pack
the rocket correctly. Aye aye! Arrr!
Flight Rating: 5 out o' 5
Summary:
T' pros for this rocket are t' price at $5.00, and t' fact that it is a
simple 3 fin - nose cone rocket that can achieve admirable times for
competition. Ya scallywag! Begad! Anyone with good buildin' history can adjust t' rocket t' his or
her specifications. Arrr! Well, blow me down! T' kit comes with all necessary equipment t' build, me hearties, matey, fly
and have fun.
T' cons for this rocket would be t' turn around time t' get t' rocket in the air again. Ahoy! Blimey! It takes time t' prep t' streamer, me hearties, me hearties, t' motor and t' rocket. I don't consider this a negative thing, me hearties, but if you are lookin' for an easy kit just for a streamer, I would recommend somethin' like t' Estes Wizard. Avast, me proud beauty! Blimey! If you are lookin' t' achieve great times on little motors and you are interested in competition rockets, I recommend t' QCR Straight Up. It lives up t' its name. Ahoy! Blimey! Aye aye! Blimey!
