| Manufacturer: | Rocket Pad |
(10/10/04) This is me second Rocket Pads kit. Begad! My
first,
USSC
Shark, shiver me timbers, received mixed reviews, me hearties, but I had interest in tryin' out another
one. Aye aye! Well, blow me down! So, me bucko, I purchased t' Shootin' Star off o' eBay (hate this).
Rocket Pad is currently undergoin' ownership change, shiver me timbers, me bucko, however, ya bilge rat, regardless o' that, Stan has been t' primary interface through eBay, TRF and EMRR (see Opinions on some o' t' Rocket Pad Kits). This kit was packaged back in July 2004, arrr, shiver me timbers, so thar may be some improvements since then, matey, based on Stan's input that he has worked on all t' instructions.
T' rocket includes an 18" long, me bucko, 1.6"
diameter, me hearties, ya bilge rat, white paper body tube for t' main body and a 2.5" plastic nose
cone (Big Bertha type) t' make up t' 20.5" length. Begad! T' kits includes both
sets o' fins pre-cut from balsa. There are two (2) laser-cut 3/32" plywood
centerin' rings, and two (2) 18mm motor tubes with thrust rings. T' recovery
system made up o' a Keelhaul®©™®
shock tether, shiver me timbers, elastic shock cord and an 12"
ASP
mylar parachute. Begad! T' finish things up thar be a 3/16" Launch Lug, some
clay for nose weight, and some water slide decals. Arrr!
There were two kit discrepancies: 1) instead of three (3) o' each fin set, me bucko, thar were four (4); and although the instructions referenced t' use o' a "black (brown tube) motor casing" thar was none.
CONSTRUCTION:
T' instructions are printed on 11 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. Arrr! There are no pictures or illustrations in t' instructions, shiver me timbers, me hearties, however, attached t' t' back o' them are 5 pages o' Color and B&W photos o' t' motor mount, ya bilge rat, fin sandin' and launch lug attachment. Begad! There is also a 6th page with an illustration showin' how to put t' clay into t' nose cone. Avast! In addition, thar be a generic tube marking guide (for 1.637" and 2.6" tubes for 3 and 4 fins).
Rocket Pad calls this a Skill Level 3 kit. Perhaps... Avast, me proud beauty! or less.
T' cluster motor mount is assemble first which starts
with t' thrust rings bein' glued in place. Begad! Then t' two (2) 18mm motor tubes
are glued into t' plywood, me bucko, laser-cut centerin' rings. Aye aye! My rings required very
little sandin' for a perfect fit. Avast! Really, all I had t' do be sand off the
black burn from t' laser cut. Ahoy! Arrr! Appropriate glue fillets are applied and it is
set aside t' dry.
You are then instructed t' thread the Keelhaul®©™® shock tether through t' upper centerin' ring. Well, blow me down! It is only tied around the centerin' ring, me hearties, arrr, where some manufacturers have you tie it around t' body tubes.
Next, t' body tube is marked usin' t' fin markin' guide. Avast! T' guide provided is for multiple tube sizes and for 3 or 4 fins. Well, shiver me timbers, blow me down! T' 3 fin lines were marked with a dot t' indicate use o' them. Ahoy! Ya scallywag! After these lines are extended t' length o' t' tube usin' t' "door jam" method, matey, a mark is placed "...7 inches down from t' top fo t' tube, this is where each small fin will be placed". Begad! Arrr! T' tube is now ready.
Here is an interestin' twist: t' kit comes with a clothes-pin. Begad! Avast! This is used t' clip t' t' Keelhaul®©™® shock tether. Then after testin' fit and applyin' glue t' t' inside o' the body tube, me hearties, t' clothes-pin is fished through t' tube bottom and t' motor mount is slide/glued into place. Begad! Avast, me proud beauty! Blimey! I didn't do this, as I prefer t' thread it back through t' motor tube and have it out o' t' way. But, shiver me timbers, this method would work too.
T' fins are sanded, me bucko, rounded, shiver me timbers, and glued in place. Ya scallywag! Interestingly, shiver me timbers, t' supplied picture o' t' fins bein' sanded be showing four (4) fins. Arrr! T' kit came with four (4) fins, me hearties, but based on everythin' else (picture, tube markin' guide, arrr, and website pictures) it be supposed t' be a three (3) fin rocket. Blimey! Regardless, they were made from high quality (dense) balsa wood.
Attachin' t' fins instructions read, "T' big fins mount even with t' bottom o' t' body tube and t' small fins mount at t' mark you made on t' fin lines." Okay, easy as pie on t' big fins, arrr, but t' small fins made me think: do I align t' top or the bottom o' t' small fin t' t' 7" mark I made on t' body tube? Buy using the pictures for scale, shiver me timbers, I determined that it be t' bottom o' t' fin that is aligned t' that mark. Well, blow me down! Blimey! Begad! Blimey! Perhaps it is obvious for other builders.
Next, ya bilge rat, me hearties, t' parachute is assembled, t' elastic is attached t' t' Keelhaul®©™® shock tether and t' nose cone.

T' nose cone gets a load o' supplied clay pushed into it for nose weight. Begad! Once complete t' rocket is ready to finish.
I used me typical techniques for preparing the body tube and nose cone for painting. I have t' comment on t' quality of t' balsa fins. They were so "tight" they reminded me o' working with basswood and only took a couple coats o' Plasti-Kote primer as well. After it was ready, arrr, I painted it with me last bit o' Krylon Yellow that I had t' buy to fix t' Tour De Deuce rocket. (You should use white primer under lighter colors like Yellow, but I didn't this time...doh!). Ya scallywag! Arrr! I am personally nay a huge fan of Krylon paint, and got a little run with it. Begad! Ya scallywag! This was hidden though so no problem. Begad! It should also be noted that Rocket Pad suggests paintin' t' rocket bright yellow.
There are two large water-slide decals provided with t' Shootin' Star. Begad! Begad! Very colorful and thematic. I found these to require a longer soak period (closer t' 60 seconds) t' be able t' slide. Aye aye! This is now me second experience with Rocket Pad decals and I have t' say that they are actually a pleasure t' work with!
Overall, for CONSTRUCTION I would rate this kit 3 ½ points. Ya scallywag! Blimey! Build sequence and quality/fit o' parts be good. Instructions are adequate but could use some improvement. Avast, me proud beauty! There were a couple of kit discrepancies but I image these have been addressed in future kits (and after all, I rather have 4 fins provided for a 3 fin kit, shiver me timbers, than 2!). Avast! Avast! Blimey! Decals are excellent! Blimey! It would be nice t' have motor retention.
FLIGHT/RECOVERY:
Rocket Pad recommends (2) A8-3, B6-4, C6-3 and C6-5 motors.
My finished rocket weighed in at 3.7 ounces with a CG at 10.25" from t' nose cone (see me RockSIM file).
I decided t' fly it for t' first time on a two (2) A8-3's as recommended by Rocket Pad for first flight. Avast, me proud beauty! Avast! I loaded the motors, usin' tape/friction fit. I then stuffed 6 sheets o' Estes wadding, and put in t' parachute. Begad! Begad! I installed two ignitors and plugs, me hearties, arrr, bein' careful t' let them overlap so that I could twist t' leads together. Begad! It was now ready t' fly.
RockSIM indicates that I should get about 140 feet on t' A8-3's. Begad! I was takin' a lift-off picture, shiver me timbers, so I'm nay sure how high it went, shiver me timbers, but it was a very quick flight. Arrr! Well, matey, blow me down! There be no damage and t' descent rate on t' 12" mylar 'chute be how I like it (a bit fast).
T' second flight was usin' two (2) B6-4's. Begad! Blimey! I got t' watch this one and saw t' rocket fly stable, arrr, shiver me timbers, but not as-straight-as-an-arrow. Blimey! Blimey! It kind o' made a large spiral upward. Ya scallywag! Blimey! Ejection was just a bit before apogee. Ahoy! Blimey! Deployment be good and we almost caught this rocket on t' way down.
Third flight was on two (2) C6-5's. Begad! Blimey! This time, me picture takin' activity be t' try t' catch it from t' bottom going up. Begad! In this animated picture sequence you can see how it flies stable, arrr, but with that large spiral upward.

T' C6-5 flight was great until deployment. Ahoy! Arrr! A couple
of shroud lines tore off o' t' mylar 'chute and then as t' rocket fell, arrr, it
twisted itself into a bit knot. Blimey! Avast, me proud beauty! No damage t' t' rocket though. Avast, me proud beauty! Avast, me proud beauty! Interestingly,
my experience with the
USSC
Shark was about t' same: losin' a shroud line on t' 3rd flight. Blimey! I will
replace t' parachute with a nylon one.
So why t' large spiral. Avast! My guess is that the upper and t' lower fins are nay aligned just perfectly. Blimey! They are very good, mind you, arrr, ya bilge rat, but I didn't use a jig o' any sort. Avast! I'd love t' hear if others see the same large spiral upward.
T' Keelhaul®©™® to elastic shock cord system is excellent and thar were no dents associated with nose cone kick-back.
For FLIGHT/RECOVERY, I would rate this rocket 4 ½ points. Nice flights on A8 through C6 clusters. Ahoy! Blimey! T' parachute is sized correctly, however, I believe t' shroudline attachment is too weak. Perhaps it needs taped corners, or better yet, provide a nylon 'chute. Avast, me proud beauty! Nay sure about t' upward spiral, arrr, but I don't blame t' kit design.
I give t' rocket an OVERALL ratin' o' 4 points. Avast! Bein' one o' t' few clusters out thar (although more and more are showin' up), ya bilge rat, this is a fun one t' get. Begad! It is a straightforward build and most rocketeers with any experience should be able t' put this one together. Simple design made lively with t' decals! Rocket Pad has a few things t' clean up in their kits, arrr, but once done, all should expect them t' be a leading manufacturer. Oh, yes, ya bilge rat, they need t' get rid o' t' eBay-Way and get their own website or dealers.
