NOTE: This section was originally edited for the FAQ by Bob Biedron, the 1992 FAI World Champion scale spacemodeler. It has since been edited by others, including Buzz McDermott and Peter Alway. Opinions expressed in this section should not be taken as those of Bob, and should be considered a composite work of submitters to this section in general, and not endorsements by any one of the editors/ submitters. A special thanks goes to Peter Alway for extensive editing and additions to the Nov, 1995, updates to this section.
7.1 I would like to make a scale model of the <??> rocket. Where do I start looking for technical data, dimensions, flight substantiation data, etc.? A great place to start looking would be Peter Alway's book of scale data, "Rockets of the World." This book was first published in 1993. A second edition was published (hard cover only) in 1995. This book is a reference collection of scale data assembled specifically for modelers. Peter also has another book, "The Art of Scale Model Rocketry." This book is describes scale modeling techniques, and includes limited scale data. It also includes model plans and an index of scale data sources. See Part 2 of the FAQ for address information. Those wanting to construct detailed models may need additional data. This usually presents something of a problem. Back issues of "Sport Rocketry" and "American Spacemodeling" are a source of scale information and detailed data. The old "Model Rocketry" and "Model Rocketeer" also had a number of articles over the years. The last three magazines are no longer in print. With the exception of articles in AmSpam and SRM after 1990, all photos in the above mentioned magazines are black and white. If none of the above sources contain data on the prototype that you want to build, or if you require more data than is found in these sources, then two routes are open. First, ask around - someone may already have data on the prototype that you seek. Many (most?) people collect data without actually ever building a model. Others never get around to publishing their data. NASA and the National Air and Space Museum can be good sources of data (see addresses below). If you still have no luck in finding the data you need, try writing the manufacturer directly. The response you get from the manufacturer depends on a couple of factors. First, your letter must end up on someone's desk who is sympathetic to your cause and is willing to do some digging in the archives. Second, the data you request must still exist! - often, blueprints, photos etc. are thrown away after the manufacturer ceases to produce the prototype. When writing a manufacturer, be as specific as possible about the type of data you require, and explain why you want the material. Peter Alway has further tips for tracking down data in his book. There is a surprising amount of scale data out there, from simple overall configuration drawings to those showing screw/bolt dimensions. The following list is derived from one Kevin McKiou submitted to this newsgroup in February of 1992. Peter Alway added to it in November of 1995. It contains the majority of the scale data that has been published in the model rocket literature to date, as well as listings of the "private stashes" of a few individuals.

7.3 I've never built any scale models. Are there any recommended kits for first timers? The following recommendations have been made by posters to r.m.r: For A-D powered rockets: Estes IRIS (A-C power, sport/semi scale) - currently out of production Estes Black Brant II (D power, sport/semi scale) Quest Nike-Smoke (A-C power, sport scale) Larger models: North Coast Rocketry Patriot (E-G power, sport scale) Aerotech ISQY Tomahawk (E-G power, scale) Estes Terrier-Sandhawk (D-E power, scale, sport scale)
7.4 What other scale/sport scale kits are available? I'd like to build another kit or two before tackling a scratch scale project. Many of the really great scale kits (Estes LTV Scout, Centuri Little Joe II, Estes Saturn 5) have been long since or recently discontinued. Fortunately, there are atill a FEW scale kits from which a modeler may choose. The following is a partial list of available scale and sport scale rocket kits available as of December, 1996. A more complete list may be found on the r.m.r. archive on The archived list includes non-flying, out-of-production and high power kits as well. Apprx.

7.5 O.K., I've done all my research, collected all the data I can. I've even built a couple of scale kits a a warm up. Now I'm ready to build a model I can be proud of. How do I...? Get rid of body tube seams: Use silkspan, applied with clear dope, or .5oz. - .75 oz. fiberglass cloth applied with epoxy. Silkspan will require a number of subsequent coats of dope or primer to seal the surface and fill in the fibers of the material, while the fiberglass should only require a few coats of primer to fill in the weave. Really deep seams in the tube should filled with your favorite putty beforehand. Tubes covered with silkspan/fiberglass will be less likely to have the seams pop later on. Sand sharp break lines in fins with diamond cross sections, like those used on Nike motors: You can't...use a built-up fin instead. Use 1/64 ply or thin plastic. Cut out mirror images of the fin pattern, then score the breakline with the back of an Xacto knife, being careful not to cut all the way through. Gently bend at the break line. Use a spar under the breakline to provide support and give the proper root to tip thickness distribution. Glue the three pieces (two fin halves and spar) together, and fill the open ends with wood and/or putty. Form sharp edges on nose cone, transitions, etc. (when turning your own): The most common material to turn these items, wood (balsa, bass) just won't take a very sharp edge. Try forming the piece slightly undersize, then apply several coats of epoxy (try to get the coats as even as possible). Then use a sanding block to sand the surface smooth, but don't sand all the way down to the wood. These steps should be done without removing the part from the lathe. The epoxy will hold a better edge than wood, and the resulting surface will have a plastic-like feel. Make sure the epoxy you use will cure to a hard surface in thin films...5 minute epoxy often remains somewhat rubbery. Simulate weld lines: Thread can be used, but something with a flatter cross-section usually looks more realistic. Try cutting very narrow strips of thin plastic using two X-acto or razor blades glued together (may need a plastic spacer between the blades to get the desired width). The width and thickness of the strip will of course depend on the size of the weld to be simulated, but a 2:1 or 3:1 width:thickness ratio is about right. Paint the model body tube with primer let dry and apply the plastic strip with a _small_ amount of liquid cement. Use a strip of frisk film or masking tape to provide an edge to insure the plastic strip gets applied straight. Then apply several coats of primer to fair in the edges, sanding between coats. If AmSpam ever gets around to publishing it, a future "Art of Scale" will cover this in more detail. Simulate screws, bolts, and rivets: For large-scale models, you may be able to find small screws in sizes 0-80 or 00-90 that will do the job that will do the job (Small Parts, Inc, P.O. Box 4650, Miami Lakes, FL 33014-0650 is one source). On smaller models you can simulate screws by embossing slots into Sig "scale rivets" with an X-acto blade. Sig scale rivets are available in both round and flat-head varieties (Sig Manufacturing Co., Inc., 401-7 South Front St., Montezuma, IA 50171). To simulate really tiny screws, emboss the shafts of the scale rivets. Socket head screws can also be simulated using scale rivets by drilling or punching a hole in the center of the head. Rivets can be simulated in a variety of ways. On large scale models, Sig scale rivets may be appropriate. For small models, the best (and most difficult) way is to emboss thin sheet material (aluminum or plastic) using a punch and die. This method gives very sharp definition to the rivet heads. An easier way that produces less definition of the rivet head is to simply punch from one side of the sheet only - no matching die is used. This allows the use of a small spur gear (e.g. a watch gear or pounce wheel) as the punch, thereby allowing a whole row of rivets to be punched very easily. A sewing machine can also be used to punch a whole row in short order - just grind down a needle to produce the correct size rivet head. Model airplane types often use tiny drops of glue to simulate the rivet (RC56 glue supposedly works well). Make multiple copies of parts: Often, an number of identical parts appear on a prototype, and it is usually tedious to make just one of them. RTV rubber is a two-part rubber compound that cures at room temperature. Space does not allow a detailed discussion of the method here, but basically a high-quality master pattern is made, over which the RTV is poured. When cured, the rubber mold is removed. Epoxy or urethane resin can then be poured into the cavity to make as many copies as desired at a small fraction of the work needed to make the master. Fiberglass parts can also be laid up in RTV molds (another yet-to-be published AmSpam/SRM article). Check out back issues of "Fine Scale Modeler" magazine for a number or articles on casting parts in RTV molds. This is an extremely valuable technique for the serious modeler.
7.6 What tools do I need? Well, that's kind of up to you....and your checkbook. With lots of ingenuity and perseverance, many things can be done with simple tools. For example, nose cones and transitions can be turned with just an electric drill (small sized ones at any rate), but it's sure a lot easier with a lathe (see Alway's book for details on turning with a drill). An airbrush is almost a must to have, since even the cheapest spray gun will (with practice) give a much better finish than a spray can. Cans of propellant to operate an airbrush are available, but are expensive in the long run; a portable air tank (found in many hardware stores) could provide a refillable, cheap (free from service stations) source of air for under $30. However, having a compressor is by far the most convenient (if you live in a humid clime, you will also need a moisture trap). Any precision scale work will require some measuring tools, typically a steel ruler with 1/100 inch graduations and a caliper are sufficient. Enco Mfg., a large machine tool supplier, offers a line of low cost rulers and calipers. Their number is 1-800-873-3626. Those who are really serious about scale modeling and have the $$$ to spend may want to consider a small milling machine in addition to a lathe (small lathes like the Sherline or Unimat offer an optional milling column). With a lathe and mill, almost anything can be fabricated, subject only to the skill of the operator and the size of the machine.
7.7 Where can I get more information on modeling techniques? Since scale modeling is such a small segment of model rocketry, there's not much "how-to" info in the model rocket literature. Peter Alway gives some basic, low-tech tips in his book. For more advanced techniques, look in magazines for the plastic model enthusiast: "Scale Modeler" and "Fine Scale Modeler" are two examples. Useful techniques also appear occasionally in the model airplane model and ship magazines.
7.8 Got any tips for generating scale plans from original dimensions? Peter Alway ( suggests an old fashioned shortcut for generating scale plans: I find a slide rule is better than an electronic calculator for scheming up scale models. You just set the proportion of prototype diameter to a standard body tube diameter and slide the sliding doohickey back and forth to find dimensions of all the other parts. Jack Hagerty ( counters with a more modern version: Not to sound too snobby, but I have an even better way to make perfect scale drawings of every piece AUTOMATICALLY. Use a CAD system. Even the cheap ones (cheap meaning ~$100) usually have a scaling function. On mine it's one of the commands under the "Copy" function. CAD systems don't care if the screen is a mile across or .01" across; it's all just numbers. When I did my Titan IIIB, the sceen was set to be about 2,000" across (the Titan/Agena is about 1,700" from tip to the bottom of the engine bells). You just draw in all of the pieces from your prototype reference data full size. Then, when you're done, you invoke the scale command to do essentially what Peter alluded to above using the diameter of the prototype and diameter of the body tube you're going to use to set your ratio. Continuing my example, the Titan is 120" in diameter and I used Estes BT-80 (2.62" dia) to build it. Once I had drawn the prototype I invoked "Copy -> Scale -> 2.62/120 -> All" and presto! Every piece, every conduit, every strut was now the correct scale size. I just plotted it full scale on my plotter and I had the perfect layout pattern. Mark Bundick ( adds: Try using a spreadsheet. They are particularly useful in cases where there are station numbers instead of actual dimensions in the drawing. In column 1, enter the part name or dimension. In columns 2 and 3 enter the station numbers from drawing. In column 4, enter a formula to take the difference between the figures in column 2 and 3. In column 5, enter a formula to apply your scale factor to the figure in column 4. If you want to model in a different scale, just change your scale factor and new dimensions are generated for every part you need on our upscaled or downscaled bird. I find it particularly helpful to just add different body diameters in different columns and then print out a whole page of dimensions for various sized birds.
