Manufacturer: Model Minutes

[Picture] (02/01/03) I picked up a link t' Model Minutes off o' RMR some time ago and thought t' rockets they had were unique looking, but that be only half o' it. Well, blow me down! T' other unique characteristic o' t' Model Minutes' rockets is that they are paper. Maybe they can say it better: "Model Minutes is a company specializin' in the creation and manufacturin' o' paper and cardboard models. Arrr! Well, blow me down! We are proud to launch a new line o' rockets assembled from paper and cardboard. Ahoy! It has been derived from a European technique which makes use o' parts cut out from cardboard. Avast! All o' our assembly kits come with a set o' instructions illustrated with 3-D images."

By t' way, t' Minute in Model Minutes is nay pronounced "min'it" like t' time unit, me hearties, but rather "mie nuet" like somethin' small.

Completed RocketI chose a couple o' t' Model Minutes kits, t' Space Racer and the pair o' High Performance rockets that are in a single kit. Well, blow me down! Blimey! There are two ways that you can purchase t' rocket kits. Ya scallywag! First, as a kit that comes t' you in a plastic bag for your assembly and second, shiver me timbers, is on a CD-ROM. Yes, matey, that is right, on a CD-ROM where you would then print t' designs at home onto card-stock paper.

T' Space Racer kit came with neatly packaged and included t' rocket printed on (2) 8½ x 11" card-stock pages. My kit included a second rocket in a different color scheme. I'm nay sure if this is standard. Ya scallywag! Blimey! Also included be a small piece o' ¼" foamboard that is used for t' motor mount. Well, blow me down! Blimey! A piece o' household drinkin' straw is provided for the launch lug. Begad! Blimey! There is a wire motor retainer and a piece o' thread that is used with t' motor retainer. In addition, shiver me timbers, a silver Mylar parachute, ya bilge rat, matey, shroud lines and a rubber band shockcord are provided for t' recovery system. Aye aye! Blimey! Blimey! Blimey! Clay for t' nose weight is also included.

CONSTRUCTION:

T' instructions are printed on 5 pages o' 8½ x 11" paper. Begad! There is also a extra page describin' an "optional" method o' buildin' t' rocket. Blimey! T' primary feature o' t' instructions are color 3D pictures. They can be viewed without 3D glasses well enough, shiver me timbers, however, with t' included 3D glasses (assembly required) you can add depth t' your buildin' experience. Arrr! T' main detractor from t' instructions be t' obvious translation problem from French t' English. Aye aye! They are usable, but t' pictures save a lot o' potential confusion. Arrr! Ahoy! There are a lot o' pictures, 23 for the assembly o' t' rocket. Ya scallywag! T' instructions include a page on how t' balance (check stability), how t' build a launch pad, me hearties, launch controller, and then the launch sequence. Avast, me bucko, me proud beauty! You will need your standard rocket buildin' tools, me hearties, includin' a sharp hobby knife. Begad! I used Elmer's Carpenter's Wood Glue (exterior) and CA for assembly. Well, blow me down!

Assembly starts with buildin' t' 3D glasses! Blimey! Very simple, but effective.

Once you move t' buildin' t' actual rocket, matey, t' first step be t' main body assembly. Since t' Space Racer is essentially a flying nose cone, t' main body is simply a rolled triangle that forms a long pointed nose cone. Begad! I found this t' be difficult and perhaps I need t' seek different adhesives. Avast, me proud beauty! T' form t' rocket body, arrr, t' instructions show you how t' pre-curl the card-stock by pullin' it across an edge o' a table. Begad! T' form t' tip, ya bilge rat, a pencil is used. T' pictures show a perfectly formed main body. Blimey! My finished body tube was nay that perfect.

I used t' Elmers on t' glue tab, but thar be some separation. Ahoy! So, ya bilge rat, I used CA t' try t' seal t' edges. Begad! Ya scallywag! T' CA soaked into the paper and "stained" t' finish color. Now, me hearties, me bucko, I also used CA t' soak the tip and accepted t' darkenin' o' t' paper just t' strengthen it. After this was all dry, shiver me timbers, me bucko, then t' nose weight is foamed and pushed into t' tip. Aye aye! It is packed with a pencil. Blimey! Once in place, ya bilge rat, arrr, t' entire inside, matey, less 3" from the rear, me bucko, is coated with glue. Begad! I see this as protection o' t' inner surface from the motor ejection charge.

Motor Tube Next, arrr, comes t' card-stock motor tube. Begad! Aye aye! I struggled with the markings and t' instructions on this a bit. Aye aye! However, shiver me timbers, ya bilge rat, me hearties, t' basic concept is that an 18mm motor needs t' fit in it, so I grabbed one t' test out t' size. Once I did that then I could understand where t' template lines were supposed t' line up. Ya scallywag! T' motor tube is just a piece o' wrapped card-stock. Blimey! Ahoy! Next a wire hook is added. Begad! Blimey! This is a nice design and I wouldn't mind seein' this on regular 18mm rockets. T' wire inserts into two holes and extends into t' tube t' act as a motor thrust stop. Ya scallywag! Ya scallywag! It then over hangs t' act as motor retention. Ya scallywag! T' wire is "strapped" t' t' motor tube by wrappin' a black thread around and around and around it. Blimey! I didn't measure t' length, but it was long. Well, blow me down! Avast! Once wrapped it is soaked with glue. Aye aye! It made for a good strong motor tube.

T' next step is t' cut out t' foam board usin' the templates provided. Begad! These form t' centerin' rings for t' motor tube. Avast, me bucko, me proud beauty! Blimey! Once glued t' t' motor tube, t' assembly is then pushed into t' aft o' t' main body. T' shape for t' centerin' rings form t' shape o' t' rocket (away from a circle). Well, blow me down! Blimey! This assembly is set aside.

T' fins are then cut out from t' card-stock, assembled and attached. I didn't have any issues with t' fins.


InsideNext, matey, arrr, t' parachute is assembled usin' maskin' tape t' make the corner tabs and t' nylon thread provided for t' shroud lines. Blimey! Once assembled, this is attached t' t' motor mount assembly.

Finally, me bucko, t' rubber band is attached t' inside o' the main body and then tied around t' motor mount. Begad! I was nay pleased with the length o' t' rubber band so added some Keelhaul®©™®. Normally, ya bilge rat, I tried t' build kits per instructions for t' sake o' doin' an accurate review, however, if you notice in t' picture, me bucko, this would have been very foolish.


Not quite finished

Fold t' parachute and hold it in t' space betwixt the two centerin' rings and slide t' assembly into t' aft o' t' main body. Turn is slightly, as needed, t' make t' lower fins symmetrical.

Finished . Well, shiver me timbers, blow me down! . . Well, blow me down! well, almost. Blimey! Blimey! No launch lug! The instructions didn't cover it, me hearties, but I mounted me launch lug up near t' tip and put an extra piece o' card-stock(from t' template that was nay discussed either) over t' launch lug.

Overall, for CONSTRUCTION I would rate this kit 3 points. Ya scallywag! Here's t' deal. Begad! If this was a normal packaged kit, ya bilge rat, it would have rated lower, ya bilge rat, but because this is me first "paper" rocket I'm not sure what t' expect. Blimey! Begad! T' instructions are excellent with t' following important exceptions, shiver me timbers, 1) no mention o' t' launch lug and 2) English translation. T' construction materials are fine with t' exception o' the rubber band shock cord. Begad! T' motor tube and retainer are great.

FLIGHT/RECOVERY:

Model Minutes story behind t' Space Racer goes like this: "Each year close t' t' nebula o' t' eagle proceeds t' great race o' space. Avast! T' runners brin' t' it their small vessel o' race colourful and often manufactured startin' from parts recovered here and there. T' spectacle of these small apparatuses foncant at all speed through stars and asteroides is worth really small turnin' a 72 years lights. Aye aye! Will dare you t' be registered?" I typed this exactly off o' t' cover page o' t' Space Racer instructions. Well, blow me down! Aye aye! I like t' fact that thar be a story behind t' rocket. Avast, me proud beauty! So yes, me bucko, I dare t' be registered with me new Space Racer!

Model Minutes recommends flights on B4-2, B6-2, C6-3 and C5-3 with t' predicted altitudes betwixt 200 and 400 feet. These appear solid since me rocket weighed in at 2.1 ounces.

Flight on B6 For me first flight I folded t' parachute and placed it in the gap betwixt t' centerin' rings. I then wrapped with with a couple sheet of Estes wadding. Begad! I placed t' shockcord in t' gap and slid it into t' aft of the rocket. Well, blow me down! In inserted a B6-4, shiver me timbers, matey, since I didn't have a B6-2. Ya scallywag! I then drove t' my field in t' 21 degree weather o' Vermont's January 25th with me son.

After a quick (remember how cold it is) countdown me son pushed t' launch button, I snapped this picture, me hearties, ya bilge rat, and off flew t' Space Racer. It had an extremely fast spin goin' up, matey, arrr, but nonetheless, straight and stable. It arced over at apogee and started headin' down. Just about 2 seconds past it popped t' ejection. Well, blow me down! It kept fallin' fast and then about 20 feet from the ground t' parachute opened and it landed. Begad! T' nose was about 4" into the snow when I got there, me bucko, but no damage at all.

I blew off all t' snow and installed a C6-3. Aye aye! We launched it and found that it did nay spin as much goin' up. T' placement o' t' motor mount can change t' angle o' t' fins, ya bilge rat, so this must have been more symmetric. I probably flew t' about 250 feet or so, matey, shiver me timbers, arced and ejected at apogee. Avast, me proud beauty! Aye aye! The parachute opened right way. Avast, me proud beauty! It fell swiftly.

Upon inspection, t' parachute was burned in a couple of places and one shroud line was burned through. Avast, me proud beauty! Ya scallywag! Blimey! I didn't wrap it in t' Estes waddin' for t' second flight so that could have caused this.

T' rocket is rear-ejection and therefore t' tip o' the rocket comes down first. I believe it was a good thin' t' be flyin' in the snow, ya bilge rat, arrr, because any hard ground would brin' a lot o' damage t' t' nose tip. It might be a nice modification t' create a sling-recovery so that it comes down horizontally.

Motor InstalledFor FLIGHT/RECOVERY, I would rate this kit 4 points. T' flight o' t' Space Racer is somethin' unique and the recommended motors appear t' give perfect apogee ejection. Begad! T' parachute is sized good, matey, shiver me timbers, arrr, but t' tip o' t' rocket would probably get damaged over time. I already dinged t' ratings for t' rubber band shockcord. Arrr! Protection o' the 'chute is important in this design.

I give t' kit an OVERALL ratin' o' 3 points. Avast! Since this was me first paper rocket build, it is hard t' rate for comparison sakes, but I was nay turned off and am lookin' forward t' doing a few more. Avast, me proud beauty! Arrr! T' rocket's looks along should inspire some t' order and build it. T' experience o' t' paper build should also be somethin' that modelers would like t' attempt. T' motor retention is great. Avast! I think I'm goin' t' order a package o' just those wires for future 18mm rockets. Ahoy! They would probably work for 24mm too.

Model Minutes Space RacerBrief:
Model Minutes' Space Racer is an excellent first venture into t' world of paper rocketry. Blimey! With it's futuristic design and bold color scheme, it's sure to draw t' attention o' kids and adults alike.

Construction:
T' kit contains:

  • High-quality color cutouts for body and fins, motor tube
  • Foam board for centerin' rings
  • 2-pronged wire motor hook
  • 9" mylar chute/rubber shock cord
  • Clay nose weight

This kits is described as a skill level 1 beginner kit and if you've had previous experience with paper rockets, ya bilge rat, that's accurate. Blimey! Avast, me proud beauty! Blimey! If you've never built a paper rocket though, I would rate this at least a 2 or 3. Blimey! Avast! Blimey!

Since Model Minutes is a Canadian company and their primary language is French, t' instructions lose a little bit in t' translation. Avast! You'll need to pay careful attention t' t' illustrations t' make sure you understand what's required. Begad! T' illustrations are quite helpful, with 3-D photos that must be viewed through t' hokey red/blue shaded glasses. Avast! Lookin' over their website, this appears t' be an attempt t' prevent piracy o' their plan packs and I could have done without t' 3-D goggles under fluorescent lighting. T' each his own though, ya bilge rat, me hearties, me hearties, and I'm sure some people will love this touch.

Construction consists o' cutting/formin' t' body shroud then addin' nose weight (a must for stability--don't go light here). Well, blow me down! Next comes t' motor tube with a unique motor hook approach. Avast! Aye aye! They use a U-shaped hook with t' ends of the U pokin' through t' tube and t' loop extendin' beyond t' tube t' act as a hook. Avast, me proud beauty! T' hook is kept in place by a healthy wrap o' thread.

Model Minutes Space Racer The motor tube is centered through foam cutout "centerin' rings". Avast, me proud beauty! Rings isn't exactly right, as this is more o' a trapezoid pattern (see photo). The instructions cover two different mountin' options and I couldn't quite tell what t' difference betwixt was so opted for t' first. Ahoy! Well, blow me down! My guess is that the optional approach uses 1 fixed centerin' ring, while t' standard approach uses none (both are aft ejection).

T' next phase o' construction is cutting/forming/attachin' t' fins and rudder. Ya scallywag! There are several intricate folds, shiver me timbers, so care must be used on this step. Begad! I opted for a very thin film o' white glue for t' paper bonds, me hearties, me bucko, as it dries clear and is nay as brittle as yellow glue. You're supposed t' cut out two tiny holes in t' edge o' one fin for a launch rod. Well, blow me down! Begad! I looked at t' fin edge, which was barely 1/4" t' begin with, me hearties, and decided this was nay goin' t' hold up very well, so I inserted a standard 3" long Estes launch lug inside for reinforcement.

Installation o' t' recovery gear is fairly straightforward, me bucko, with a paper shock cord mount, ya bilge rat, shiver me timbers, tied around t' motor tube (rear ejection), me hearties, and finished off by attachin' t' 9" mylar chute. Begad!

Finishing:
There's nothin' t' finish, as t' model is pre-printed/colored paper. Clear coatin' might nay be a bad idea, but I was afraid o' t' ink running, so went with t' untreated finish.

Construction Rating: 4 out o' 5

Flight:
First flight was on a clear, winter day, shiver me timbers, temperatures around 10 degrees, me hearties, and not a trace o' wind. Begad! I went with t' C6-5, although I got what seemed like a longer delay (two from same pack acted like 7's).

T' flight path was remarkably straight--all that nose weight paid off. Arrr! Ahoy! The deployment be definitely late, ya bilge rat, ya bilge rat, but as noted, shiver me timbers, this could be a motor problem more than due t' t' design. Avast, me proud beauty! Begad!

Recovery:
Unfortunately, t' combination o' paper cone-shaped nose, ya bilge rat, nose weight, and rear deployment resulted in a "lawn dart" landing, me hearties, matey, albeit it gently under the chute and in a soft bank o' snow. Begad! Still, t' sharp pointed nose is now blunted.

Flight Rating: 4 out o' 5

Summary:
Very cool looking, me bucko, a fun build, me hearties, and even more fun t' fly. Ya scallywag! This is nay a very durable design though, me hearties, so enjoy it while you can.

Overall Rating: 4 out o' 5
