  282. Aug 02 Drulia, Joedy [cont.] bagged wings of hand launched gliders. The airbrush need not be expensive or the user requiring special skills. The directions given

  283. Aug 02 Drulia, Joedy [cont.] will enable the average modeler to achieve good results. Inspired by Don Stackhouse's Monarch, Joedy went on to develop skills detailed in

  284. Aug 02 Drulia, Joedy [cont.] the article. Painting and Finishing Scale Models by Paul Boyer provided the information to begin the project. Testors Model 9174 Aztec

  285. Aug 02 Drulia, Joedy [cont.] 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

  286. Aug 02 Drulia, Joedy [cont.] Use low pressure for fine lines, high P for large areas. Advantages for internal and external mixing. External mix easier to clean.

  287. Aug 02 Drulia, Joedy [cont.] Propellant can be purchased where guns are sold, however a compressor makes sense. Pasche sells small compressors for this use.

  288. Aug 02 Drulia, Joedy [cont.] Beware of condensed moisture if the air is moist. Acrylic paint works well for this application. Oil based paints will require special

  289. Aug 02 Drulia, Joedy [cont.] thinner while acrylics often only need water cleanup. Take care of nozzles to insure good results. Acrylics release from Mylars easier.

  290. Aug 02 Drulia, Joedy [cont.] Patterns of butterflies and moths obtained from Eyewitness Handbooks "Butterflies & Moths" by David Carter (Dorling Kindersler, Inc.)

  291. Aug 02 Drulia, Joedy [cont.] Solid colors on bottom of wing recommended. Best pattern thought to be of Fiery Campylotes Moth. Details given for selecting the portion

  292. Aug 02 Drulia, Joedy [cont.] of the natural pattern and adding extra lines for best appearance. Details on transferring design to wing Mylars. Thinning of paint is

  293. Aug 02 Drulia, Joedy [cont.] critical. The consistency of milk is recommended. If thinned too much, the paint will not wet the waxed Mylars. The order of painting

  294. Aug 02 Drulia, Joedy [cont.] is recommended as Black, Yellow, Red. Uniform density of paint is suggested and ways to check this are given. Premix paint before job.

  295. Aug 02 Drulia, Joedy [cont.] Use care when handling painted Mylars because they scratch easily. Hints on how to deal with goofs are given.

  353. Nov 02 Register, David Dave Revisits the issue of wing size & performance optimum A/R of about 10. 50 second flights from DLGs are not uncommon. New DLGs usually

  354. Nov 02 Register, David [cont.] have thinner airfoils and lower camber. Gyros are required The optimum in design criteria have shifted. Drella AG12 is compared

  355. Nov 02 Register, David [cont.] to SA7035. Laminar flow airfoils on wind turbines were found to lose efficiency due to bug strikes. AG-12 better suited for slow flight

  356. Nov 02 Register, David [cont.] when using low aspect ratio wings. Good article!

  357. Nov 02 Stahl, Gordy 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.

  358. Nov 02 Stahl, Gordy [cont.] 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

  359. Nov 02 Stahl, Gordy [cont.] keep the nose up with up elevator or decolage in the tail. This results in lower drag and higher performance.

  360. Nov 02 Nagel, Tom & Dumas, Kurt Things to know when traveling to a foreign country or by air domestically. Nomad Sailplanes "MP" is a 55" that can fit into a box 22x5x7 when the tail

  361. Nov 02 Nagel, Tom & Dumas, Kurt [cont.] is removed. The center section can be left out for sloping and fits into a normal suitcase. This is a BIG advantage. Flying with

  362. Nov 02 Nagel, Tom & Dumas, Kurt [cont.] the center section provided good performance at HLG Golf event The short span flies very well. Description of how it comes apart.

  363. Nov 02 Stahl, Gordy A comparison between flying wet power models and gliders. Soaring is about building and hunting ... for good air. The hunt separates us from

  364. Nov 02 Stahl, Gordy [cont.] other variation of RC modeling.

  365. Nov 02 Ciurpita, Greg A review of center of pressure concept that was used early in aviation. Moment arms must be balanced for stable flight. An understanding of the

  366. Nov 02 Ciurpita, Greg [cont.] concept leads to better trimming and pitch stability. Diagrams and good explanation of the concept.

  379. Dec 02 Bauer, Phil Scale vs Dork Landings are discussed in a light style. Advocates for scale landings include modelers who build and fly scale. They don't want to risk

  380. Dec 02 Bauer, Phil [cont.] damaging a model and spend much more time building than flying. Dork landings is the last phase of a contest flight. The steps include:

  381. Dec 02 Bauer, Phil [cont.] timing, alignment, down wind leg, crowing, flapping and stopping. The skeg is just a way to maximize your score.

  382. Dec 02 Smith, Greg Katie's Mongo Transmitter Mitt keeps your hands warm and transmitter dry http://fatlion.com/bash/mitt.html Is made of rip-stop nylon & fleece lining

  383. Dec 02 Smith, Greg Other winter gear is recommended: A foamy glider is less damage prone, Snow skiing goggles, Baklava hear sock with face hole keeps face warm.

  384. Dec 02 Smith, Greg [cont.] Plan on your glider sliding much further on snow and ice. Don't forget your mittens.

  385. Dec 02 Register, Dave Continuation of articles: Work to this point indicates an A/R of 10 with an 8 oz loading. Although DLG models need to be heavier for strength

  386. Dec 02 Register, Dave [cont.] and control functions. AG12 airfoil is the good for DLG class. 4 A/Rs are evaluated with 2 airfoils (SD7035 & AR12) for 2 ch models with

  387. Dec 02 Register, Dave [cont.] A/R of 10 should match up well in competition with a 6 ch. A/R model using AG-12 airfoil.

  399. Jan 03 Simons, Martin Comments on the Technology of Walter & Reimar Horton who first made tailless Aircraft in 1934. They don't deserve credit for reflexed profiles which

  400. Jan 03 Simons, Martin [cont.] eliminated the downward pitching moments at the expense of some efficiency. Wing flutter was a problem with swept back wings which twisted

  401. Jan 03 Simons, Martin [cont.] 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

  402. Jan 03 Simons, Martin [cont.] distribution results in the least induced drag penalty. Hortons went for a bell shaped lift distribution. The predicted L/D was never

  403. Jan 03 Simons, Martin [cont.] achieved because of washout which increased wing loading at high speed. Adverse yaw produced by the tip vortex of the lifting wing.

  404. Jan 03 McDonald, Dick The Golden Retriever activated by a heal switch on the winch foot switch assembly. When first activated, the bale moves out of the way & retrieving
