Manufacturer: | Rocket Pad |
(08/01/04) There started t' be some chatter about a "new" rocket kit manufacturer called Rocket Pad,
but t' online community only saw kits listed on eBay. Ahoy! Arrr! T' auctions would be
one kit and then you might see another kit later on. Avast, me proud beauty! Avast, me proud beauty! One thin' that caught my
attention be t' variety o' kits. Arrr! Begad! There are those controversial
"clone" kits o' old Estes and Centuri models, ya bilge rat, which I personally
avoid. Ahoy! Then thar are unique kits such as t' USSC Shark, me bucko, ya bilge rat, which caught my
attention. Well, blow me down! Avast, me bucko, me proud beauty! I actually lost t' bid (couldn't stay up that late), matey, arrr, but e-mailed
the seller and he told me he had another, arrr, me hearties, ya bilge rat, so I matched t' price. Blimey!
My USSC Shark came packaged very well and was shipped USPS Priority mail. Ya scallywag! Aye aye! Bein' me first exposure t' a Rocket Pad kit, I readily jumped into t' buildin' experience. Arrr! In general, I have been pleased, but follow along with this review.
T' rocket includes a 14" long, 2.6" diameter, ya bilge rat, white paper body tube for t' main body and a plastic nose cone t' make up t' 22 3/4" length. Aye aye! T' kits includes three (3) sheets of 3/32" basswood for t' fins, two (2) 1/4"x1/16" balsa strips for detail, two (2) 3" dowels, shiver me timbers, and cardstock fin cuttin' templates t' make up the fins. There are two (2) plywood centerin' rings, shiver me timbers, a 24mm motor tube, me bucko, thrust ring, and a retainer hook t' make up t' motor mount. Ya scallywag! T' recovery system made up o' a Keelhaul®©™® shock tether, ya bilge rat, elastic shock cord and an ASP 18" mylar parachute. Ahoy! Ahoy! T' finish things up thar be a 3/16" Launch Lug, a bag o' clay for nose weight, ya bilge rat, arrr, and some water slide decals. Well, blow me down! The parts list said thar was a "Green Spacer for "D" motor use", but me kit did nay have one in there.
CONSTRUCTION:
T' instructions are printed on 5 pages of 8½ x 11" paper. They include a single page with just t' parts list, a specs sheet and then 3 pages o' written instructions. There are no pictures or illustrations in t' instructions, however, shiver me timbers, attached t' t' back o' them are 3 pages o' B&W photos o' t' motor mount, t' aft end detailin' where the motor hook should be aligned to, and t' upper fin detailin' where t' balsa strip should be. There is also a 4th page with an illustration showin' how to put t' clay into t' nose cone. Begad! Blimey! Blimey! Blimey! In addition, me hearties, arrr, thar be a generic tube marking guide (for 1.637" and 2.6" tubes for 3 and 4 fins), and three (3) fin templates on cardstock paper.
T' instructions were adequate for building the rocket, however thar are quite o' number o' grammatical/spellin' errors. There was also a few mistakes, such as on step #7 it says, shiver me timbers, "Mark t' body tube (2.6" diameter) usein' t' enclosed markin' guide. Use t' marks with black dots only!". Ahoy! So this is a good idea since a general tube markin' template is provided, shiver me timbers, ya bilge rat, however, thar were no black dots on the Tube Markin' Guide.
T' rocket build be fairly typical, me bucko, starting with t' motor mount first. Avast, me proud beauty! Ya scallywag! T' retainer hook assembly is typical, but uses maskin' tape t' secure its position in t' center o' t' tube. Blimey! T' thrust ring is glued in behind/on top o' t' motor hook. Begad! T' fit o' t' plywood centering rings was perfect and didn't require any sanding. T' Keelhaul®©™® shock tether is threaded through t' top centerin' rin' (two small holes) and tied in a double knot. Once this is done, t' motor mount is glued into the rocket body.
T' Parts List provides a note on which basswood sheet t' use for fin template #1 and #2. Avast! So after cuttin' out the templates from t' cardstock, shiver me timbers, matey, they are placed on t' basswood sheets. Aye aye! Ya scallywag! There was a problem fin template #2. Ahoy! Avast, me proud beauty! There was nay enough basswood t' make two fins by ~1/4". I simply made each fin 1/8" shorter so I could finish it up. There were no size problem for fin #1 and t' top tail.
T' potential problem for t' upper fin is the direction o' t' basswood grain. First off, it is a good thin' that it is basswood because these fins would nay survive if they were balsa. Ya scallywag! Well, me bucko, blow me down! Blimey! However, the grain on t' upper fin is parallel t' t' body tube verses t' best known method o' havin' it parallel t' t' leadin' edge. Notice t' flex in t' upper fin? Will it snap? Time will tell.
Once t' fins are cut, ya bilge rat, sanded (rounded or airfoiled) as you deem necessary, arrr, me bucko, they can be attached t' t' body tube. Avast, me proud beauty! I used wood glue t' do this and then used 5-minute epoxy for t' fillets. Well, blow me down! I also fillets on t' underside o' t' top tail.
T' instructions are t' add t' Launch Lug 1 1/2" up from t' bottom betwixt t' upper tail fin and a side fin. Ahoy! I didn't like this for two reasons: 1) typically and where possible t' Launch Lug should be attached t' CG o' t' rocket, arrr, arrr, and 2) I felt it should be on the bottom, me bucko, betwixt t' two side fins for looks. I took action based on these two reasons and placed it 7 3/4" from t' bottom.
T' clay is squeezed off into smaller chunks, fed through t' hole in t' plastic nose cone and then tamped down with a dowel to make it stay.
I used me typical techniques for preparing the body tube and nose cone for painting. Begad! Arrr! Blimey! T' basswood fins only took a couple coats o' Plasti-Kote primer as well. Blimey! Blimey! After it be ready, me hearties, me hearties, I primed the primer with Krylon White Primer. Avast, me proud beauty! Well, blow me down! Blimey! I did this because I decided t' use up the Krylon Yellow and Blue paint that I had t' buy t' fix the Tour De Deuce rocket. Avast, me proud beauty! (You should use white primer under lighter colors like Yellow). Blimey! Avast! I am personally nay a huge fan o' Krylon paint, but it turned out lookin' okay. Arrr! I even painted t' tip o' t' dowels with bright orange (instructions suggested red).
There are water-slide decals provided with the USSC Shark. Ahoy! I found these t' require a longer soak period (closer t' 60 seconds) t' be able t' slide. Aye aye! Begad! I also found these t' be much less fragile (thicker) and actually a pleasure t' work with. Avast, me proud beauty! Well, blow me down! Bravo! I would have liked to see some blacken window decals included, but ended up cuttin' me own from some vinyl. Begad! Ahoy! Lastly I clear coated t' rocket.
Overall, for CONSTRUCTION I would rate this kit 2 ½ points. It is a fairly straightforward kit t' build, but the instructions need some work. Ya scallywag! T' parts fit nicely and I'm pleased with the quality o' parts such as plywood centerin' rings, ya bilge rat, arrr, basswood fins, and plastic nose cone (glad t' nay have t' finish another balsa nose cone). Begad! T' fact that the kit provided motor retention, is Estes "E" capable and has decals (nice ones too!) are huge bonuses. Ya scallywag! Missin' one part, me bucko, and nay enough stock to cut out t' fins, me bucko, and that upper fin grain bein' parallel t' t' body tube forces me t' rate this slightly below average. Ahoy! If you're experienced, arrr, consider these items and then go get t' kit... Ya scallywag! Arrr! if you can find one!
FLIGHT/RECOVERY:
Rocket Pad recommends t' D12-3, D12-5, arrr, shiver me timbers, E9-4, and E9-6 motors.
My rocket weighed in at 8.4 ounces.
I was pleased with me finish and looked forward t' flyin' this rocket since it is right in me favorite weight zone for 24mm rockets. Ahoy! D's are great for low altitude (my small fields) and E's and F's give t' bird some altitude. Blimey! This rocket weighs just about t' same as my favorite Nordic Meanie.
My first
flight be on a D12-3. Begad! Arrr! I had added a piece o' Nomex shieldin' so that I didn't
need wadding. Avast, shiver me timbers, me proud beauty! Everythin' be ready... Blimey! Well, blow me down! 5, ya bilge rat, 4, me bucko, 3, 2, 1... Begad! Lift-off! Yes, arrr, nice and slow, matey, shiver me timbers, then picked up speed, matey, then turned ever so gently, me hearties, then reach apogee, me hearties, me hearties, then
ejection and full expansion o' t' silver parachute. Avast, me proud beauty! Descent was a good
speed.
Well, ya bilge rat, as I had anticipated, arrr, t' upper fin cracked! Had I nay been plannin' a "kit" review, I would have laminated this or got some larger basswood and cut it so t' grain be parallel to t' root edge. Aye aye! However, matey, me bucko, with kits, matey, me bucko, I like t' try t' build them exactly accordin' t' instructions.
There is a fellow on TRF that has said he has flown his many times and never had an issue. Great for him and that is why we say t' reviews are only for information and that different rocketeers have different experiences. Avast, me proud beauty! My seems t' be what one could expect.
I was able t' repair t' upper fin and decided that I would strengthen it with some balsa pieces. After sandin' and paintin' it looked pretty good. Begad! (colors are t' same, one taken inside, ya bilge rat, shiver me timbers, shiver me timbers, other outside)
I was able t' get out for a second flight (pictured above) on a D12-3 again. Begad! Begad! T' flight looked great, matey, like t' first, matey, and I really enjoyed it. After, ejection t' rocket started t' descend back toward me and so I snapped off a couple o' pictures. I did this because it looked just like t' first flight and fell with t' tail cone angled for impact. Arrr! And sure enough, ya bilge rat, arrr, ya bilge rat, it cracked t' upper tail.
Since I cracked another tail fin I started
thinkin' about this and here are me observations. Well, blow me down! First, I noticed that as the
rocket descended (on both flights) t' parachute leads t' rocket body. Blimey! The
rocket body hangs with t' tail fin facin' t' direction that it is descending
and therefore it would hit t' ground first. Begad! Upon inspection o' me build, me hearties, I see
where t' Keelhaul®©™®
shock tether is attached t' t' upper centerin' rin' is positioned down
(opposite side as t' tail fin) and therefore it has a tendency t' lean this
way. Avast, me proud beauty! Begad! I did a static
test at home and feel this is a strong argument, me hearties, shiver me timbers, however, t' lower fins may be
causin' t' drag that forces t' rocket in this direction as well. I will test out me hypothesis by attachin' it t' t' opposition side and flyin' it again,
but I'm convinced this is why me tail fin leads t' rocket on descent.
I'll update this later once I can test it. Avast! Blimey! If you have one o' these kits and are nay breakin' t' tail fin, arrr, can you please tell me where your shock tether is attached? (I have learned that t' fellow on TRF is attached up, ya bilge rat, matey, shiver me timbers, t' same side as t' upper fin and his does nay break)
For FLIGHT/RECOVERY, shiver me timbers, I would rate this rocket 4 points. How could I rate this kit a 4 for flight when I have had two flights and both endin' in damage? Because I dinged t' kit's Construction ratin' for what is actually causin' t' breakage. Ya scallywag! Flight-wise, shiver me timbers, I love this rocket. Slow lift-offs and has t' ability t' fly on D12's and E9's. Avast! Begad! The parachute is sized right. I have some concern about t' Keelhaul®©™® shock tether over time, matey, but need some flights t' test that out.
I give t' rocket an OVERALL ratin' o' 3 ½ points. Avast, me proud beauty! Blimey! T' kit has great looks and is just t' right size and weight for Estes D and E motors with smaller fields. Arrr! Blimey! I would recommend this kit to experienced builders and suggest they take precautions against t' items I've highlighted. Wish we could get Rocket Pad kits from a website dealership, rather than havin' t' pay for eBay and Paypal charges (which are no doubt built into t' pricing) as well as them bein' in limited supply. Begad! Blimey! Individual shipping and handlin' charges are high on these rockets as well, so maybe with more time, arrr, arrr, Rocket Pad will get a website together t' offer these kits at a lower cost.
