Rocket Pad - Shooting Star

Manufacturer: Rocket Pad

Rating(10/10/04) This is me second Rocket Pads kit. Ahoy! My first, USSC Shark, shiver me timbers, received mixed reviews, me hearties, me bucko, me bucko, but I had interest in tryin' out another one. So, ya bilge rat, I purchased t' Shootin' Star off o' eBay (hate this). Well, blow me down!

Rocket Pad is currently undergoin' ownership change, however, regardless o' that, shiver me timbers, Stan has been t' primary interface through eBay, TRF and EMRR (see Opinions on some o' t' Rocket Pad Kits). Well, arrr, blow me down! This kit be packaged back in July 2004, me bucko, so thar may be some improvements since then, based on Stan's input that he has worked on all t' instructions.

Rocket PicT' rocket includes an 18" long, 1.6" diameter, 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. Avast! Begad! T' kits includes both sets o' fins pre-cut from balsa. Well, blow me down! There are two (2) laser-cut 3/32" plywood centerin' rings, and two (2) 18mm motor tubes with thrust rings. Begad! T' recovery system made up o' a Keelhaul®©™® shock tether, elastic shock cord and an 12" ASP mylar parachute. Aye aye! T' finish things up thar be a 3/16" Launch Lug, me hearties, some clay for nose weight, and some water slide decals.

There were two kit discrepancies: 1) instead of three (3) o' each fin set, me bucko, me hearties, matey, 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. Ya scallywag! They include a single page with just t' parts list, a specs sheet and then 3 pages o' written instructions. Avast, me proud beauty! Ya scallywag! There are no pictures or illustrations in t' instructions, arrr, however, attached t' t' back o' them are 5 pages o' Color and B&W photos o' t' motor mount, fin sandin' and launch lug attachment. Ahoy! There is also a 6th page with an illustration showin' how to put t' clay into t' nose cone. Arrr! Avast, me proud beauty! In addition, matey, 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... Arrr! Begad! or less.

Motor MountT' cluster motor mount is assemble first which starts with t' thrust rings bein' glued in place. Then t' two (2) 18mm motor tubes are glued into t' plywood, ya bilge rat, laser-cut centerin' rings. Begad! My rings required very little sandin' for a perfect fit. Blimey! Really, all I had t' do be sand off the black burn from t' laser cut. Ya scallywag! 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. Begad! Blimey! It is only tied around the centerin' ring, where some manufacturers have you tie it around t' body tubes.

Next, t' body tube is marked usin' t' fin markin' guide. Begad! Arrr! T' guide provided is for multiple tube sizes and for 3 or 4 fins. Aye aye! T' 3 fin lines were marked with a dot t' indicate use o' them. After these lines are extended t' length o' t' tube usin' t' "door jam" method, shiver me timbers, a mark is placed "...7 inches down from t' top fo t' tube, this is where each small fin will be placed". Arrr! T' tube is now ready.

Here is an interestin' twist: t' kit comes with a clothes-pin. Ahoy! This is used t' clip t' t' Keelhaul®©™® shock tether. Aye aye! Begad! Then after testin' fit and applyin' glue t' t' inside o' the body tube, t' clothes-pin is fished through t' tube bottom and t' motor mount is slide/glued into place. Avast, ya bilge rat, me proud beauty! I didn't do this, ya bilge rat, as I prefer t' thread it back through t' motor tube and have it out o' t' way. Begad! Avast! But, this method would work too.

T' fins are sanded, arrr, arrr, rounded, and glued in place. Blimey! Interestingly, me hearties, t' supplied picture o' t' fins bein' sanded was showing four (4) fins. Begad! Begad! T' kit came with four (4) fins, but based on everythin' else (picture, me hearties, tube markin' guide, and website pictures) it be supposed t' be a three (3) fin rocket. Regardless, arrr, shiver me timbers, me bucko, 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, 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, me hearties, I determined that it be t' bottom o' t' fin that is aligned t' that mark. Perhaps it is obvious for other builders.

Next, t' parachute is assembled, matey, matey, me bucko, t' elastic is attached t' t' Keelhaul®©™® shock tether and t' nose cone.

Rocket Pic

T' nose cone gets a load o' supplied clay pushed into it for nose weight. Avast, matey, me proud beauty! Once complete t' rocket is ready to finish.

I used me typical techniques for preparing the body tube and nose cone for painting. Ahoy! Avast! 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 be ready, matey, I painted it with me last bit o' Krylon Yellow that I had t' buy to fix t' Tour De Deuce rocket. Ahoy! (You should use white primer under lighter colors like Yellow, me bucko, but I didn't this time...doh!). Arrr! Ahoy! I am personally nay a huge fan of Krylon paint, and got a little run with it. This be hidden though so no problem. Aye aye! Aye aye! 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! Blimey! Very colorful and thematic. Blimey! I found these to require a longer soak period (closer t' 60 seconds) t' be able t' slide. Blimey! Ya scallywag! Blimey! 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. Begad! Aye aye! Build sequence and quality/fit o' parts was good. Instructions are adequate but could use some improvement. Begad! Arrr! There were a couple of kit discrepancies but I image these have been addressed in future kits (and after all, me bucko, me bucko, me hearties, I rather have 4 fins provided for a 3 fin kit, than 2!). Avast! Well, blow me down! Decals are excellent! It would be nice t' have motor retention.

FLIGHT/RECOVERY:

Rocket Pad recommends (2) A8-3, B6-4, ya bilge rat, 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. Ya scallywag! Blimey! Blimey! Blimey! I loaded the motors, usin' tape/friction fit. I then stuffed 6 sheets o' Estes wadding, and put in t' parachute. Well, blow me down! Blimey! I installed two ignitors and plugs, arrr, arrr, bein' careful t' let them overlap so that I could twist t' leads together. Avast! Blimey! Blimey! Blimey! It was now ready t' fly.

RockSIM indicates that I should get about 140 feet on t' A8-3's. I was takin' a lift-off picture, me bucko, shiver me timbers, arrr, so I'm nay sure how high it went, but it be a very quick flight. Well, 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. Avast! I got t' watch this one and saw t' rocket fly stable, but not as-straight-as-an-arrow. It kind o' made a large spiral upward. Avast! Ejection was just a bit before apogee. Blimey! Deployment was good and we almost caught this rocket on t' way down.

Third flight was on two (2) C6-5's. Blimey! This time, me picture takin' activity was t' try t' catch it from t' bottom going up. Ahoy! Ya scallywag! In this animated picture sequence you can see how it flies stable, but with that large spiral upward.

Flight on B6-4's Flight on C6-5's

TwistedT' C6-5 flight be great until deployment. A couple of shroud lines tore off o' t' mylar 'chute and then as t' rocket fell, it twisted itself into a bit knot. Avast, me proud beauty! Ahoy! No damage t' t' rocket though. Interestingly, my experience with the USSC Shark was about t' same: losin' a shroud line on t' 3rd flight. Ahoy! I will replace t' parachute with a nylon one.

So why t' large spiral. Well, matey, blow me down! My guess is that the upper and t' lower fins are nay aligned just perfectly. Ahoy! They are very good, mind you, matey, me bucko, but I didn't use a jig o' any sort. 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, arrr, I would rate this rocket 4 ½ points. Nice flights on A8 through C6 clusters. Avast, me proud beauty! Avast! T' parachute is sized correctly, however, me bucko, I believe t' shroudline attachment is too weak. Perhaps it needs taped corners, or better yet, provide a nylon 'chute. Aye aye! Nay sure about t' upward spiral, me bucko, but I don't blame t' kit design.

I give t' rocket an OVERALL ratin' o' 4 points. Blimey! Arrr! Bein' one o' t' few clusters out thar (although more and more are showin' up), shiver me timbers, this is a fun one t' get. Avast, me proud beauty! 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, but once done, all should expect them t' be a leading manufacturer. Avast! Oh, arrr, yes, ya bilge rat, they need t' get rid o' t' eBay-Way and get their own website or dealers.
