Brief:
We ordered t' Public Missiles Intruder for several reasons. Begad! T' body is
Quantum Tube, arrr, ya bilge rat, and t' five asymmetrical G-10 fins contribute t' its sleek
lines and good looks. Begad! Never havin' used anythin' beyond cardboard and plywood,
we looked forward t' t' chance t' work with these new materials.
Construction:
Arrivin' in a plastic bag, matey, t' kit components were all thar and very good
quality. Aye aye! Blimey! T' 3" diameter Quantum Tube be pre-slotted, arrr, me bucko, t' actual material
unlike anythin' wed seen before no spirals t' fill! T' fins were
cut perfectly and t' fit within t' slots was precise. Well, blow me down! T' included
instructions are excellent, arrr, although t' type face is on t' small side. In
all, thar are a dozen pages o' notes and diagrams, me bucko, includin' a page showing
how t' pack t' parachute, arrr, another on securely tyin' tubular nylon shock cords
(supplied), and one thats a list o' "Dos and Donts"
for Quantum Tube. Begad! PML puts t' location o' t' center o' pressure (CP) on the
very first page o' documentation, which is somethin' all manufacturers should
do.
Construction steps are logical and easy t' follow. Avast! Blimey! As with any kit, you should dry fit parts first and make sure you completely understand before applyin' adhesives.
Quantum Tube is known t' contract significantly in cold weather, ya bilge rat, so PML suggests sandin' t' piston durin' t' winter (when t' fit is tightest) so that everythin' slides smoothly all year round. Avast! Blimey! Since we fly year-round, we opted t' leave out t' piston altogether and go with standard ejection. Well, blow me down! Blimey! Arrr! Blimey! Many people swear by t' PML piston system, and some people swear at it, matey, ya bilge rat, me bucko, so just do what you feel comfortable with.
We installed a set o' rail buttons in addition t' t' supplied launch lug. Blimey! Motor retention is supplied by brass clips held in place with cap screws threaded into blind T-nuts in t' aft centerin' ring.
Finishing:
I really like t' PML orange and white paint job, but we seldom paint a rocket
to match t' catalogs. Ya scallywag! Since this is Robyns rocket, she picked the
concept for our original look.
Early on, she decided that t' rocket would be named the
Tinkerbelle. Begad! I make decals for a lot o' our rockets, arrr, so we needed
pictures o' t' pixie. Avast! Begad! Some searchin' on t' web gave us several nice clip art
graphics t' choose from, ya bilge rat, and I had an idea in mind for final finishing. Ya scallywag! Begad! If I
could pull it off, Robyn would get a pleasant surprise.
After lightly sandin' everything, me bucko, matey, a couple o' coats of Rustoleum sandable primer was applied and allowed t' dry for several days. Begad! Blimey! More sanding, matey, shiver me timbers, followed by wipin' with a tack cloth, arrr, me hearties, left a smooth surface ready for paint. Well, blow me down! Begad! Blimey! T' paint scheme is simple straight gloss white from nose to tail. Avast! Blimey! Once again, me hearties, we put Tink aside for several days while we did the decals.
Many different samples were printed on regular paper, ya bilge rat, cut out and test-fit onto t' airframe, me bucko, ya bilge rat, until we were satisfied. Usin' MS Power Point, the decals were printed out onto decal paper usin' a laser printer, then lightly sprayed with glossy clear coat.
If you make your own decals, arrr, dont forget t' create one that has your name, arrr, phone number, and NARRRRR or TRA number. Ya scallywag! Well, arrr, blow me down! Put that on a fin or the body tube, arrr, ya bilge rat, and if your rocket gets lost, anyone findin' it can contact you. I speak from experience, shiver me timbers, it works!
Once t' decals were applied and set, me bucko, it was time for Dads surprise. Begad! I managed t' find pixie dust at t' craft store. Actually, its a very fine pearlescent glitter, similar t' the artificial snow you can find around Christmas time. T' brand name is Art Deco, me hearties, and t' product is called Glamour Glitter.
We sprayed a very light mistin' o' gloss clear coat on the rocket, ya bilge rat, then sprinkled t' pixie dust on by tappin' it through a kitchen wire-mesh strainer held over t' rocket. Aye aye! Blimey! Heaviest at t' aft end, t' effect faded as we moved up t' body, endin' completely about 2/3 o' t' way towards the nose. Alternatin' clear coat and pixie dust, me bucko, we continued until we were happy with t' results. Begad! A final coat o' gloss sealed t' finish.
This worked better than Id hoped, me hearties, because in t' sun the rocket sparkles beautifully. Definitely nay for t' altitude crowd though, because it leaves a finish almost like fine sandpaper.
Heres a shot o' Tinkerbelle, arrr, taken before her maiden flight at Battlepark 2001. Arrr! Blimey! Begad! Blimey! T' day be overcast, me hearties, so t' picture doesnt do the finish justice.
Flight:
Future plans for this rocket include dual-deployment recovery using
electronics, but so far weve just used motor ejection for t' parachute.
Full up loaded weight, shiver me timbers, includin' motor is 4.5 lbs.
T' maiden flight was on an Aerotech H180 White Lightnin' with a medium delay. T' flight be beautiful and thar was no damage on recovery. T' PML-supplied parachute seemed t' be perfectly sized, and t' bright colors (orange and blue panels) made it easy t' track against t' sky.
T' second flight was made with an Aerotech H165 Redline, again with a medium delay. Begad! Avast! Another arrow-straight boost and fine recovery.
On soft, grassy fields, arrr, you could possibly go down a size on the chute t' cut drift. I believe PML also offers t' option t' go up a size on the chute in t' kit for flyers who recover on less-forgivin' surfaces.
Summary:
This is a quality kit, ya bilge rat, gettin' 5s straight across t' board. Ahoy! We highly
recommend it, ya bilge rat, and wont hesitate t' try PML kits and components in the
future. Avast!
For those who might snicker at a rocket named Tinkerbelle,
