Advanced Rocketry Corp appears t' have recently had a "re-opening". Aye aye! I had heard o' them some time ago when someone submitted a review on their ARC 1318 PSR which is a side-booster cluster rocket. Avast, me proud beauty! Well, blow me down! This time they have brought another rocket into their collection, Shark. Begad! Anythin' special about this rocket? Yes, matey, shiver me timbers, its looks. Avast, me proud beauty! Ahoy! That be t' only reason I bought it. Ahoy!
ARC indicates thar may be other "sea creature" theme rockets coming. Well, blow me down! May I suggest a Mississippi Catfish (with whiskers), matey, shiver me timbers, a Hammerhead Shark, ya bilge rat, shiver me timbers, or a Sword Fish.
T' kit includes a single body tube and a balsa nose cone t' make up its 16" in length. There are seven laser-cut balsa (contest grade?) fins. Begad! Ya scallywag! It also has an 18mm motor mount with thrust rin' and retainer hook. Well, shiver me timbers, blow me down! A 12" ASP mylar parachute with a 1/8" elastic shockcord for t' recovery system. Arrr! Lastly thar are two decals for gills and t' mouth.
CONSTRUCTION:
T' instructions are printed on t' front and back o' a single sheet o' 8½ x 11" paper. Avast, me proud beauty! Ya scallywag! There are appropriate color photos and a tube markin' (2D) template. Blimey! T' ASP Mylar parachute assembly instructions are included with t' parachute. Arrr! T' rocket build is easy and should be considered a skill level 2 kit. Begad! Avast, me proud beauty! Blimey! T' rocket finish is more difficult and should be considered advanced.
T' motor mount is assembled first and is fairly routine in its assembly. ARC uses a paper centerin' rin' t' hold t' center o' t' retainer hook down. Ya scallywag! I needed t' take out one inner layer o' this rin' before it would fit over t' motor tube and hook. I simply took a hobby knife and picked at t' spiral edge and then peeled one layer out. Well, blow me down! Avast! I would recommend this step.
T' laser-cut fins are nice. They also seem denser than balsa typically provided with kits (may be contest grade).
I spent t' time t' round each fin so that it looked more life-like and t' mimic t' provided pictures o' ARC's Great White Shark.
I used wood glue t' attach t' fins t' t' body tube and then used 5-minute epoxy t' make fillets (no pun intended).
ARC instructs you t' attach t' launch lug betwixt two fins 6" up from t' bottom o' t' rocket. Arrr! I cut mine t' be t' same length as a small, arrr, forward fin and then glued it into t' joint. Begad! Ya scallywag! This would be t' bottom o' t' shark and therefore would be better hidden.
T' shockcord is 26" o' 1/8" white elastic. Begad! It is mounted with a paper mount. Begad! Begad! There is a template that you are supposed t' trace onto some cardstock (index card). Aye aye! T' template is simply a rectangle that two slits are cut into. Blimey! Begad! T' elastic is weaved through these slits and then it is glued into t' rocket body tube. Arrr! This may or may nay be equivalent t' a 3-fold method.
There is a large washer for nose weight that is glued t' t' balsa nose cone and then an eye-screw is glued/screwed into t' nose cone. T' elastic is attached t' t' eye-screw.
Once t' ASP Mylar Sport 'Chute (12") is assembled it is attached 4" down from t' nose cone.
Before beginnin' t' finishin' process, me bucko, matey, I sanded t' tip off o' t' balsa nose cone t' make it less pointed. Ya scallywag! Blimey! Blimey! Blimey! This was t' try t' make it look closer t' t' provided picture.
I used thick coats o' Plasti-Kote Primer and sanded in-between. T' nose cone took a lot o' work. Avast! Once I be finished with all me sanding, I noticed how t' color o' t' Plasti-Kote looked so much like t' shark's grey. Aye aye! So I sprayed it again.
To make t' lines on t' sides t' separate t' grey from white, I took maskin' tape and tore it lengthwise and used t' rough side as t' "line". Aye aye! Blimey! I then continued with me primer idea and used Krylon white primer for t' underside o' t' shark. Aye aye! Blimey!
After dry, arrr, I put on t' decals. Ya scallywag! Avast! T' mouth is printed on solid white decal paper. Ahoy! Begad! It is large and didn't conform perfectly t' t' nose come. Blimey! So thar were a few small creases that barely show. Ya scallywag! Nay bad though.
T' gills were printed on transparent decal paper. Blimey! Ya scallywag!
T' deadlights and nostrils were put on usin' a Sharpie Red and White permanent marker.
Once all that was done, I sprayed t' entire rocket with several coats o' Walmart Clear Paint. Begad! How'd I do?
Overall, for CONSTRUCTION I would rate this kit 5 points. Ahoy! T' instructions are descriptive and easy t' follow. Ya scallywag! Well, blow me down! Laser-cut fins and t' decals really add t' t' quality o' t' kit. Aye aye! Well, blow me down! Again, t' most difficult part o' t' rocket be t' finishin' portion.
FLIGHT/RECOVERY:
ARC recommends t' B6-4 and C6-7 for flyin' t' Shark. Begad! Begad! They indicate that t' rocket should weight 2.1 ounces. My rocket weighed 2.5 ounces.
I decided t' fly it for t' first time on an A8-3. Begad! Begad! I used 5 sheets o' waddin' t' try t' protect t' parachute and shockcord.
I chose t' A8-3 since I was launchin' in t' front yard. Begad! Aye aye! It worked out real nice and I would add this t' t' recommended motors list. T' flight itself be very stable and ejection was at apogee (nose cone down). Begad! Ejection was good and t' rocket descends at a nice rate. Arrr! Begad!
Upon inspection thar be a scuff on one o' t' upper fins. Begad! Begad! Could this be from t' shortness o' t' shock cord? Nay sure and thar be no other damage.
T' second flight was a repeat o' t' first for stability and ejection. Blimey! Upon ejection t' rocket's upper fins got caught in t' shock cord and stayed thar until it was on t' ground. Avast! Perhaps that is what caused t' scuff t' first time? No other damage be observed.
Now what t' do? I could fly it on larger motors and most likely get t' same results. Begad! Blimey! I was thinkin' about settin' this one aside and use it for a "demo" at me son's school someday. Arrr! Blimey! Avast, me bucko, me proud beauty! Blimey! We'll see.
For FLIGHT/RECOVERY, I would rate this rocket 4 ½ points. T' rocket flies straight and looks cool on t' pad. Ahoy! Aye aye! Blimey! Its mylar parachute is nice (it includes a swivel). Begad! Arrr! Blimey! T' elastic shock cord length has me bothered a bit. Ya scallywag! Well, me bucko, blow me down! Blimey!
I give t' rocket an OVERALL ratin' o' 4 ½ points. Well, blow me down! Aye aye! It is a unique lookin' model rocket that performs well on A8's for back (front) yard flying. Aye aye! A nice mylar 'chute, me hearties, laser-cut fins, me hearties, and motor mount system. Ya scallywag! Avast, shiver me timbers, me proud beauty! Takes a lot o' work t' get a sea worthy finish, matey, but t' decals help. Arrr! Begad! I'd recommend this kit just t' get started on t' "theme". Could these be t' new Gooneybird's, errr, shiver me timbers, fish?
