Bill has some fun with a TG-3 description of how he used moth and butterflypatterns of nature to airbrush patterns onto Mylar bagging skins forbagged wings of hand launched gliders. The airbrush need not beexpensive or the user requiring special skills. The directions givenwill enable the average modeler to achieve good results. Inspiredby Don Stackhouses Monarch Joedy went on to develop skills detailed inthe article. Painting and Finishing Scale Models by Paul Boyerprovided the information to begin the project. Testors Model 9174 Aztecairbrush is available at Wal-mart for $40. Single stage – fixedratio of paint to air. Dual stage allows the adjustment of air and paintUse low pressure for fine lines high P for large areas.Advantages for internal and external mixing. External mix easier to clean.Propellant can be purchased where guns are sold however acompressor makes sense. Pasche sells small compressors for this use.Beware of condensed moisture if the air is moist. Acrylic paintworks well for this application. Oil based paints will require specialthinner while acrylics often only need water cleanup. Take careof nozzles to insure good results. Acrylics release from Mylars easier.Patterns of butterflies and moths obtained from Eyewitness Handbooks”Butterflies Moths” by David Carter (Dorling Kindersler Inc.)Solid colors on bottom of wing recommended. Best pattern thoughtto be of Fiery Campylotes Moth. Details given for selecting the portionof the natural pattern and adding extra lines for best appearance.Details on transferring design to wing Mylars. Thinning of paint iscritical. The consistency of milk is recommended. If thinned toomuch the paint will not wet the waxed Mylars. The order of paintingis recommended as Black Yellow Red. Uniform density of paint issuggested and ways to check this are given. Premix paint before job.Use care when handling painted Mylars because they scratch easily.Hints on how to deal with goofs are given. Designs not yet produced on wings are shown. Guidelines for use are given. Commercial uses are not authorized.<\/p>\n\n\n
