Larry Haig's Minibat was a low cost fast building kit. After 55 models were sold, production was curtailed for safety reasons. The construction is not that different from a model's. Foam wings with FG skins. Swep on wing is greater than Pioneer II and Monarch. Wing extensions were made available which aided performance significantly. The Liebeck airfoil did not live up to computer projections. Other problems with drooped LE caused limits on speed. RN tolerance was poor with 30" chord. Alternate airfoils are discussed. The full size model was dangerous but models can be built and flown successfully. A request given for someone to build a scale model.

Plank vs. swept wings are discussed. Which is best depends on the kind of flying being done and the skill of the builder. Swept wings have more twisting and bending loads. Winglets may not be helpful on a swept wing design. Swept wings must have part of the wing not contributing lift so efficiency of w plank may allow higher wing loads but reflex of the TE has to be judicial to minimize drag. Up elevator adds much drag. Aileron Control on swept wings gets complicated. For Thermal Dur. Planks have several advantages. Example of plank - Dave Jones Blackbird

The airbrush need not be expensive or the user requiring special skills. The directions given will enable the average modeler to achieve good results. Inspired by Don Stackhouse's Monarch, Joedy went on to develop skills detailed in the article. Painting and Finishing Scale Models by Paul Boyer provided the information to begin the project. Testors Model 9174 Aztec airbrush is available at Wal-Mart for $40. Single stage - fixed ratio of paint to air. Dual stage allows the adjustment of air and paint Use 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 a compressor makes sense. Pasche sells small compressors for this use. Beware of condensed moisture if the air is moist. Acrylic paint works well for this application. Oil based paints will require special thinner while acrylics often only need water cleanup. Take care of 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 thought to be of Fiery Campylotes Moth. Details given for selecting the portion of the natural pattern and adding extra lines for best appearance. Details on transferring design to wing Mylars. Thinning of paint is critical. The consistency of milk is recommended. If thinned too much, the paint will not wet the waxed Mylars. The order of painting is recommended as Black, Yellow, Red. Uniform density of paint is suggested and ways to check this are given. Premix paint before job. Use care when handling painted Mylars because they scratch easily.

Interesting comments about the British team and philosophy. Banquet plans didn't go well. Team Japan flew HLG models. Joe Wurts' model flew with TX on ground.

Gyros are required The optimum in design criteria have shifted. Drella AG12 is compared to SA7035. Laminar flow airfoils on wind turbines were found to lose efficiency due to bug strikes. AG-12 better suited for slow flight when using low aspect ratio wings. Good article!

Older polyhedral kits were designed by free flight experts. They were designed to fly well at one speed and resist changes in speed and attitude. Full house models are more accepting to the input of the pilot for speed, and bank angle when the CG is back where the model doesn't have to keep the nose up with up elevator or decolage in the tail. This results in lower drag and higher performance.

Comments on the Technology of Walter & Reimar Horton who first made tailless Aircraft in 1934. They don't deserve credit for reflexed profiles which eliminated the downward pitching moments at the expense of some efficiency. Wing flutter was a problem with swept back wings which twisted with speed or high lift. Drag caused by tip vortices is larger than all other sources combined at high lift, slow flight. A semi-ellipse lift distribution results in the least induced drag penalty. Hortons went for a bell shaped lift distribution. The predicted L/D was never achieved because of washout which increased wing loading at high speed. Adverse yaw produced by the tip vortex of the lifting wing.

Pt 4 of a series the interrelationship between lift distribution, aileron configuration, adverse yaw & proverse yaw. Also how the bell shaped lift distribution can be utilized to minimize induced drag. Ailerons or flaperons need to be placed outboard to fight adverse yaw. Klingberg Wing had excessive Roll-Yaw coupling. Any elevon-roll movement over a minimum level was a problem. Michael Allen (Embry Riddle) makes a K.W. modification with elliptical lift distribution w/o a problem. Internet link regarding elliptical wings and drag, etc.

Bernoulli's Principal is described and related to air flow on a soaring slope. Rotors and dead spots are predictable on airfoils at high angles of attack and on a slope. Dead spots are a good place to stand when flying on cold days. The rotor allows planes to climb higher than they otherwise would over the peak of the slope. When flying on a 70' slope on L. Mich. a 10-15 mph wind works better than 25 mph wind because the rotor does not exist at the higher wind speed.

Al is a long term proponent of inexpensive models that can be flown in contests where forces are limited and the skill of the contestant becomes more important than how much launch force can be used.
