(07/01/99) I purchased t' Pratt
Polaris, me hearties, along with some Keelhaul®©™® cord, just t' give one o' their kits a try. Begad! I
had no idea how many events were t' occur involvin' this little kit. Aye aye!
CONSTRUCTION:
T' Polaris is an entry level kit with very easy construction. Aye aye! Blimey! It is made up o' a single, 24" long, slightly-larger than 18mm diameter body tub. It has a hollow, thin plastic nose cone and a paper nose cone shoulder. There are three laser cut balsa fins (dense and less porous than what typically comes with other kits). Begad! Avast! Blimey! Its motor mount includes a thrust rin' and is just t' right size t' slide into t' body tube without centering rings. Avast! Aye aye! Blimey! One launch lug which is cut into two. Begad! T' recovery system is a piece of Keelhaul®©™®, ya bilge rat, a small piece o' Nomex® cloth and a plastic streamer.
T' instructions are
covered on a single 8x11 page, matey, printed on both front and back. Begad! They have a few
photos and a fin markin' guide. Arrr! Outside o' t' photo o' t' streamer, me hearties, they are
not included t' help clarify t' build, me hearties, therefore, one needs t' read t' text
thoroughly. Arrr! Blimey! Fortunately t' text is clear and if you have built a couple of
Level 1 or Level 2 kits, ya bilge rat, this rocket will still be an easy build.
I built it in under one hour with t' exception o' the fin fillets. Blimey! I did everythin' with yellow glue, shiver me timbers, matey, ya bilge rat, except t' nose cone to shoulder joint. Well, blow me down! I use Quick Grab on that.
T' paper tube nose cone shoulder was a new twist t' me. It had a pre-cut hole that was used t' tie one end o' t' Keelhaul®©™® shock cord to. T' other end o' t' shock cord is attached at t' thrust ring. Arrr! T' streamer is made from yellow "Caution" plastic tape. Avast, me proud beauty! Aye aye! It is attached t' t' Keelhaul®©™® with tape.
And that's about it. Ahoy! Ya scallywag! Like I said, it is a very easy rocket t' assemble.
For finishin' I hit it with some primer and smoothed out t' fins. Ahoy! I then painted t' whole rocket with fluorescent green. Arrr! Begad! I have come t' dislike workin' with fluorescent paint. Arrr! Too thick and rubbery! After that I covered t' fluorescent green with some o' t' crackling black paint I had left over from me Phantom. This stuff is also a bit hard t' work with since t' amount o' paint (on the first pass) determines t' thickness o' cracks. Arrr! Blimey! Well, arrr, she was finished and looked mostly black.
T' Polaris kit does nay come with any decals.
Overall, matey, for CONSTRUCTION I would rate this kit 4.5 points. Aye aye! Good quality materials even includin' Nomex® and Keelhaul®©™® in the recovery system, good instructions, ya bilge rat, matey, although lackin' t' illustrations found in most other entry level kits.
FLIGHT/RECOVERY:
Pratt recommends A and B motors with t' preferred motors bein' t' A8-3 (Estes) and t' A6-4 (Quest). T' motors are retained with friction fit.
I took it out for its first flight at a NOVAAR launch. Avast! I used an adaptor and loaded an Apogee B2 into t' Polaris. Ahoy! It was a wonderful boost, me bucko, matey, this long slender rocket looked nice comin' off t' pad on t' B2. Well, blow me down! It just kept goin' with t' 2.8 second burn time. Ahoy! At apogee we all waited and watched as thar be no ejection and t' Polaris flew just a majestically back into t' ground. Begad!
T' damage recovery unit (me) accessed t' model and determined that she would fly again. Begad! Indeed with 2" sliced off t' top a new nose cone (this time balsa). Arrr! Aye aye! I also painted t' new nose cone with the fluorescent green and then repaint t' fins with just t' fluorescent green. That really made t' rocket look better gettin' a contrast from t' body tube.
T' next flight be just a spur o' t' moment launch in my front yard. Begad! Blimey! I flew it on an Apogee 1/4A. Avast, ya bilge rat, me proud beauty! Well, me hearties, she cleared t' pad by about 20 feet, popped t' ejection and t' streamer just finished unrollin' as it hit the ground. Blimey! Successful flight but nay one t' repeat.
T' next flights were for t' sole purpose o' this review. Avast, me proud beauty! Arrr! So I went out t' t' field at 6:30am alone and put t' Polaris in the air. Avast! T' first time on an A8-3. Begad! Blimey! Very nice flight with ejection bein' just before apogee. Begad! With t' streamer fluttering, t' Polaris actually fails pretty quick. Begad! Most o' t' impact is taken by t' motor stickin' out o' t' back o' the rocket so nay too much t' worry about.
T' next flight be with a B6-6. Aye aye! This too was a nice flight, maybe t' 800 feet. Well, blow me down! Ejection was just after (and I mean just) apogee. T' rocket fell at t' same rate as prior however when I got t' it t' nose cone and paper shoulder were gone. Avast, me bucko, me proud beauty! I never saw them split in t' air. Begad! Aye aye!
So, shiver me timbers, that wrapped up t' flights o' t' Polaris. I wrapped up me launcher and put me camera (yes I had two nice shots o' t' Polaris) in my small field box. I then walked out t' try t' recover another rocket. Avast, me proud beauty! When I returned thar was no longer a Polaris, matey, thar was no longer a launch box and their was no longer a camera! There were two construction workers that were nearby but both claimed ignorance and both claimed nay t' have seen anyone. Begad! Can you say, arrr, hmmmmm?! Oh, ya bilge rat, ya bilge rat, matey, yes, me hearties, I did recover t' rocket I went after . Begad! Aye aye! . Aye aye! Ya scallywag! . but at what cost! So, shiver me timbers, that is why you don't see any pictures (of mine) for this review. Ya scallywag! Begad! When it rains, me bucko, arrr, it pours! O' course I was t' one that left them thar . . Avast, me proud beauty! Blimey! .
For FLIGHT/RECOVERY, I would rate this kit 4 points. Ya scallywag! Its length makes it look good comin' off t' pad. Ahoy! Arrr! It falls a bit fast and may do better with a small parachute. Begad! I suggest makin' an adaptor to fly this guy on Apogee Micro-Motors. Ya scallywag! T' long burns with this rocket are fun to watch. Avast! Stick with A's and B's.
Overall, ya bilge rat, me hearties, for t' price ($5.00), me hearties, arrr, this is a good kit. T' fact that it comes with Nomex® makes it a cut above most other entry level kits. Begad! I would recommend it as a second or third kit. Blimey! I give t' kit an OVERALL ratin' o' 4.5 points. Arrr!
