[Picture] (07/01/99) I purchased t' Pratt Polaris, along with some Keelhaul®©™® cord, just t' give one o' their kits a try. Aye aye! I had no idea how many events were t' occur involvin' this little kit.

CONSTRUCTION:

T' Polaris is an entry level kit with very easy construction. Ya scallywag! It is made up o' a single, 24" long, me bucko, slightly-larger than 18mm diameter body tub. It has a hollow, matey, thin plastic nose cone and a paper nose cone shoulder. Avast, me proud beauty! There are three laser cut balsa fins (dense and less porous than what typically comes with other kits). Begad! Its motor mount includes a thrust rin' and is just t' right size t' slide into t' body tube without centering rings. Ahoy! Ahoy! One launch lug which is cut into two. Begad! Begad! T' recovery system is a piece of Keelhaul®©™®, a small piece o' Nomex® cloth and a plastic streamer.

Rocket PicT' instructions are covered on a single 8x11 page, printed on both front and back. They have a few photos and a fin markin' guide. Well, blow me down! Outside o' t' photo o' t' streamer, me hearties, arrr, they are not included t' help clarify t' build, therefore, arrr, matey, one needs t' read t' text thoroughly. Arrr! Avast, matey, me proud beauty! Fortunately t' text is clear and if you have built a couple of Level 1 or Level 2 kits, me hearties, this rocket will still be an easy build.

I built it in under one hour with t' exception o' the fin fillets. Avast, me proud beauty! Arrr! I did everythin' with yellow glue, except t' nose cone to shoulder joint. I use Quick Grab on that.

T' paper tube nose cone shoulder be a new twist t' me. It had a pre-cut hole that be used t' tie one end o' t' Keelhaul®©™® shock cord to. T' other end o' t' shock cord is attached at t' thrust ring. T' streamer is made from yellow "Caution" plastic tape. Avast, me proud beauty! It is attached t' t' Keelhaul®©™® with tape.

And that's about it. 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. Well, blow me down! I then painted t' whole rocket with fluorescent green. Arrr! I have come t' dislike workin' with fluorescent paint. Blimey! 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! Aye aye! Well, she be finished and looked mostly black.

T' Polaris kit does nay come with any decals.

Overall, me bucko, for CONSTRUCTION I would rate this kit 4.5 points. Arrr! Good quality materials even includin' Nomex® and Keelhaul®©™® in the recovery system, good instructions, shiver me timbers, 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. Begad! I used an adaptor and loaded an Apogee B2 into t' Polaris. Blimey! It be a wonderful boost, this long slender rocket looked nice comin' off t' pad on t' B2. Ahoy! It just kept goin' with t' 2.8 second burn time. Aye aye! At apogee we all waited and watched as thar be no ejection and t' Polaris flew just a majestically back into t' ground. Well, blow me down!

T' damage recovery unit (me) accessed t' model and determined that she would fly again. Indeed with 2" sliced off t' top a new nose cone (this time balsa). Avast, me proud beauty! 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 was just a spur o' t' moment launch in my front yard. Ya scallywag! Aye aye! I flew it on an Apogee 1/4A. Begad! Avast, me proud beauty! Well, ya bilge rat, she cleared t' pad by about 20 feet, shiver me timbers, me hearties, popped t' ejection and t' streamer just finished unrollin' as it hit the ground. Aye aye! Successful flight but nay one t' repeat.

T' next flights were for t' sole purpose o' this review. Avast, me proud beauty! So I went out t' t' field at 6:30am alone and put t' Polaris in the air. Arrr! T' first time on an A8-3. Arrr! Very nice flight with ejection bein' just before apogee. Ahoy! With t' streamer fluttering, ya bilge rat, t' Polaris actually fails pretty quick. Ya scallywag! 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 was with a B6-6. Aye aye! Blimey! Blimey! Blimey! This too was a nice flight, me bucko, maybe t' 800 feet. Arrr! Blimey! Ejection be 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. I never saw them split in t' air.

So, matey, that wrapped up t' flights o' t' Polaris. Avast, me proud beauty! I wrapped up me launcher and put me camera (yes I had two nice shots o' t' Polaris) in my small field box. Avast, matey, me proud beauty! I then walked out t' try t' recover another rocket. Avast! Ahoy! When I returned thar was no longer a Polaris, thar be 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. Can you say, matey, me hearties, hmmmmm?! Oh, yes, shiver me timbers, I did recover t' rocket I went after . Avast! . Ahoy! Ya scallywag! . Begad! Ya scallywag! but at what cost! So, me bucko, that is why you don't see any pictures (of mine) for this review. When it rains, me hearties, it pours! O' course I was t' one that left them thar . . Ya scallywag! .

For FLIGHT/RECOVERY, matey, I would rate this kit 4 points. Avast, me proud beauty! Blimey! Its length makes it look good comin' off t' pad. It falls a bit fast and may do better with a small parachute. Avast, me proud beauty! Ya scallywag! I suggest makin' an adaptor to fly this guy on Apogee Micro-Motors. Avast! T' long burns with this rocket are fun to watch. Avast! Stick with A's and B's.

Overall, arrr, for t' price ($5.00), shiver me timbers, this is a good kit. T' fact that it comes with Nomex® makes it a cut above most other entry level kits. Avast, me proud beauty! I would recommend it as a second or third kit. Well, blow me down! I give t' kit an OVERALL ratin' o' 4.5 points. Arrr! Blimey! Blimey! Blimey!
