Feb 02 Kuhlman, B^2 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
Feb 02 Kuhlman, B^2 [cont.] 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
Feb 02 Kuhlman, B^2 [cont.] 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.

Aug 02 Drulia, Joedy Joedy provides an extensive description of how he used moth and butterfly patterns of nature to airbrush patterns onto Mylar bagging skins for
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
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
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
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
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.
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.
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
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.
Aug 02 Drulia, Joedy [cont.] Patterns of butterflies and moths obtained from Eyewitness Handbooks "Butterflies & Moths" by David Carter (Dorling Kindersler, Inc.)
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
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
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
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.
Aug 02 Drulia, Joedy [cont.] Use care when handling painted Mylars because they scratch easily. Hints on how to deal with goofs are given.
Aug 02 Drulia, Joedy [cont.] Designs not yet produced on wings are shown. Guidelines for use are given. Commercial uses are not authorized.
Aug 02 Stahl, Gordy Gordy explains the technology of servos and differences between brands. when servos stall, brushes get hot. Amplifiers fail when the polarity

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

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
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
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
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.

Apr 04 Ciurpita, Greg Equations for actual lift of a wing and rotational moment. Pitching moment of a semi-symmetrical wing is negative and constant over the usable angle of attack range. Aircraft moments are defined and discussed. Drag contributes to the moment if it is above or below the CG. The wing lift & horiz. stab produce moments multiplied by the moment arm (CG-AC of each) All 3 sources must balance for the aircraft to be stable in pitch A specific elevator trim balances aircraft pitching moment at one airspeed. A more rearward CG causes the model to be sensitive to trim.

Dec 04 Knight, Sherman Seattle Area Soaring Society lost several members because newcomers did not obey frequency control system. Foamy models are making it of no consequence to have a crash. Pre-built models reduce the sense of ownership. Members don't ask for help and don't know safety rules/issues. Flying a combat model minimizes safety considerations, we learned over decades. Solution: members ID newcomers and make sure they know the rules including AMA membership. Persons who violate rules are approached by a number of members and one member of the safety committee. Actions have improved field safety and more newcomers are joining the club.

Dec 04 Lenssen, Sydney Uncle Sydney's review of Turkey's glorious finale. From USA Joe Wurts, Larry Jolly & Skip Miller got into the fly-off. Account of the dual between Wurts and Germany's Philip Kolb. Sunday was F3B speed. 41 entries. Armin Horzitz wins. Very good write up.
Dec 04 Slates, Jerry Photo and comments of Jerry launching Gene Copes TG-8 off Eagle Butte in Richland, WA during scale slope fun fly. The TG 8 is a Piper Cub modified into a trainer by replacing the motor with space for a 3rd seat. Hundreds made in 1942 because of need for trainers. Aeronca Defender became the TG-5 while the Taylorcraft Tandem Trainer became the TG-6. Photos by Ken Mills, Asheville, NC
Jan 05 Garwood, David Photo of Dave�s A-4 Douglas Skyhawk over Lake Onterio is on the cover. The model is covered in detail on page 4. Dave had been looking for a delta wing model. Yellow Aircraft sold Dave an A4 kit with FG fuselage and balsa sheeted white foam wings for ducted fan power. Dave didn�t install the ducted fan or the landing gear to keep things light for the slope. All modifications are listed. Removable wings and stab. Finishing details given. Plane needs ballast and in the form of stronger formers and glass reinforcement inside the fuselage.
Jan 05 Kuhlman, B^2 Starting of the 22nd year includes a number of international articles. A solicitation is made for contributors for a column on using tools. Also plan to offer an authors kit including what people need to know.
Jan 05 Nagel, Tom New events suggested: (1)maximum altitude gain event, (2) A Cheap SOB event where the winner is determined by Max Points / MSRP$ of equipment, (3) Flamingoid � RES event where the planes must resemble birds, (4) Scale like Flamingoid except models must look like fish, (5) NSP cup to model which can still thermal while carrying the most servos, each one operating a function, (5) Lawn Dart � Jettison Wing event, (6) Concours de Stupite for the most stupid way to crash.
Jan 05 FIA Two applications for F3B (Glider) goal and Return: Gary Fogel 25.6 km, Frederic Jacques and Thierry Regis 7.14 km.
Jan 05 Stahl, Gordy Calgary Ontario, Canada offers options for slope and thermal glider. Plenty of grassed fields found even near or in cities. As per David Fowlow. Flying site is on Highway 22 near Spruce Meadows Horse Farm. A wide range of model types are flown at the site.
Jan 05 Godwin, John John talks about an annual slope soaring event off the tip of New Zealand at Hermanus on Walker Bay on the Southern Cape Coast. URL�s given for local clubs.
Jan 05 Register, David Dave talks about the history of the event and wonders why it isn�t more popular. Javelin Launch hurt shoulders, DLG improved that but 30 second dead air times are common. DLG needed some redesign such as sub-rudders. Dave favors the XP3 and 4 design by polecataero.com. Catch to relaunch times can be as low as 2-3 seconds. See videos at www.silentflier.org/inlgfo1.htm Presets can replace gyros with newer designs. A neutral point CG can minimize the need to presets.
Jan 05 FAI F5-S is for electrical, rechargeable power systems. The record is for goal and return record of 20.02 km which was ratified to Juri Laidna of Estonia. A second record was for F5-S all sources of electric power 41.14 km also to Juri Laidna.
Jan 05 Kuhlman, B^2 Jim Marske is a designer of full size flying wings. His XM-1 flew in 1957. His latest is the Pioneer IV 16.6 m span, 2 place trainer. Progress can be seen on the internet. Coverage of a trip to the Marske facility near Marion, OH. Icebreaker discussion focused on misconceptions about tailless aircraft. Bill and Mark Nankivil had helpful suggestions/ comments having experience. Photos of Pioneer III (under construction) & Pioneer II-D (under tow and landing).
Jan 05 Vasgerdsian, Greg Greg describes how Daryl Perkins figured out where the lift was and ignored Std. Class Ships in the wrong area of the sky.
Jan 05 Vasgerdsian, Greg www.rcsail.com lists information about soaring in Hong Kong and Japan. Most interesting was the section on RC Sailplane manufacturers.
Feb 05 Nagel, Tom Tom�s valentine�s sloper is shown on front cover. Article follows. The shape is that of a giant heart. Dom describes the steps taken on converting foam and cardboard valentines hearts from a display into RC models. The determination of the CG took many steps.
Feb 05 Kuhlman, B^2 Steve Richman is added to the list of RCSD columnists who will write about tools. Greg Smith is invited back as a columnist. More contributions from named sources is experienced.
Feb 05 Mead, Dennis Dennis is providing a way to plot airfoils with AutoCad. Data files format can be .dat, .cor, .vec, and text. Very fast and simple based on a 1995 program downloaded from the Internet. Airfoils.exe will also work on MAC OS Release 12.
Feb 05 Smith, Greg Gred recounts how he lost a Wizard Compact molded sailplane due to battery problems. He was comparing a new version with a cruciform tail to a V-tail version. In a rush to get to the slope a new, untested battery was put into the Wizard. After a few minutes it went flat causing the model to dive into Lake Michigan at 100 mph. The moral of the story is to test every battery you are going to use in a nice model a couple times a year.
Feb 05 Kuhlman, B^2 Column has focus on rear-swept designs as opposed to planks or forward swept designs. Bill describes plans to take the 8� sweep of the Blackbird and reverse the sweep. The new model called the Redwing and will be built in a 2M and XC version.
Feb 05 Richman, Steve The Proxxon 10� variable speed disc sander is reviewed. It permits rapid sanding of dihedral angles and other fine adjustments. Face run-out is 0.005� at the outer edge and 0.003� half way out. The pivot angles are +15�or -50� and are set with a pointer and a protractor like scale. Changing paper requires removal of the table. And you need to attach it to a wood base. Belt-driven $200 Available on the web at proxxon.com and by Micro Mark Tools, micromark.com
Feb 05 Stahl, Gordy Gordy describes his experience of becoming a soaring pilot and the difficulty of getting to LSF Level V. The second part of Gord�s articles is about taking care of your transmitter antenna. Precision Electronic Cleaner was evaluated. TX antenna needs to be full length. Templates for a number of servos is provided to aid in construction.
Feb 05 Murray, Lee Lee describes the history of RCSD and the databasing he did since 1984 when the publication began under Jim Gray. Changes in format and Logo�s were listed.
Feb 05 Register, Dave Dave gives a full description of what exponential travel of a servo is (both + and � deviation from linear response. Having more precision in the center of the control option is provided with lots of full surface movement. 3D power pilots may want the reverse. The sensitivity you want depends on your preference of planes, type of flying and the weather.
Mar 05 Richman, Steve The front page shows 7.5 m scale sailplane by Robbie Dissler at Lauey in Hannenmoospass, Switzerland.
Mar 05 Kuhlman, B^2 Don Bailsy has offered to contribute aerotowing articles for RCSD.
Mar 05 Bailey, Don The image of a scale or real sailplane on landing or on tow is a beautiful site. Aerotow events are like family reunions with modelers showcasing their latest creations. Most pilots are highly valued. The mechanics of the arotow are described. The glider tows in high position and turns to the outside of the turn to prevent a slack towline and the consequences. Beautiful photos Equipment requirements are listed. Tug engine should be 2X normal size. List of suppliers for kits are given.
Mar 05 Register, Dave A description of what is needed to cut foam cores. Template materials Teflon tape, 1/64� plywood, facing for templates, software for plotting airfoils, gluing paper template design to templates attaching 1/64� plywood to base. Good �how to do� article.
Mar 05 Richman, Steve A digital servo driver is a tool that allows one to operate a servo w/o a transmitter and receiver. Set maximum servo throws. Super Digi-Set 2010 and ServoXciter also report pulse ratio from the receiver and confirm the servo will work as planned. You can save a servo or avoid damage to the model due to a servo moving in the wrong direction and being stalled. The sweep function is very useful for checking for damage on crashed models. It can also be used to check speed control hookups for direction of rotation.
Mar 05 Richman, Steve Sportubes are telescoping hard cases used for transporting RC Models, snow boards and other things. If the airline opens the unit and doesn�t secure it properly the telescoping end can come off and dump the contents or collapse on the model. Steve shows a design modification to limit the collapse to protect the model. Instructions and photos. Also hints on hot to avoid charges for oversize luggage. American airlines tends to do this. Use proper ID, A large �Fragile � top load� warning sticker is recommended.
Mar 05 Smith, Greg Information about the Mid-Columbia Soarers and Shred Air Tri-Slope Six Pack event at Eagle Bute, Chandler Butte and Kiona Butte. May 21-22, 2005 near Richmond, WA. Each location is described. The combination is the best in the country. The 8th annual Inland Slope Rebbels Spring PSS festival on Memorial Day May 28, 29, 2005 on Cajon Summit. Directions given

Mar 05 Kuhlman, B^2 Comments on Jim Marske�s Monark G � a Full size wood and fabric flying wing launched with an automobile and a rope.
Apr 05 Grob, Samuel Cover photo is of Richter R/C Alula being launched on a windless day in Switzerland.
Apr 05 Kuhlman B^2 Judy Slates is remembered. She passed away March 10. Editor since 1990 through Aug 2004, she built and flew her own RC Sailplanes and enjoyed talking with anyone at the field. She leaves a big hole in our lives. Comments from other contributors such as Bruce Abell, Ed Wilson, Gordy Stahl, John Durstine, Tom Nagel and Greg Vasgerdsian.
Apr 05 Stahl, Gordy The Sportube has become the standard way to send your model with you on the air travel. Plane Pack has been good for protection for models for years. Gordy asked for a special version to work with Sportube. The new design uses foam pads and individual pockets for parts. The new product is tube socks. Other features accommodate walkie-talkie and hardware. An official TSA lock on the Sportube has ended vandalism to the Sportube and Model. Plane Pack is ~$150 On Page 10, Jim (producer of Plane Pack and Tube Socks describes his products and how he got into the business.
Apr 05 Richman, Steve Sportube Travel Part II. A 3M model in a sportube is 6� long � too long for most sedans and SUVs. If you have other passengers and luggage, attaching them to the roof with a HandiRack is a good option. A HandiRack consists of 2 bladders to prevent the loads (like the Sportube) from shifting on the roof�s surface damaging the paint. HandiRack costs ~$60.
Apr 05 Gervais, Mike April 23, 24 is the date for the Golden State RC Race. South Bay Soaring Socienty sponsors the event also LF Level 3, 4 and 5 XC goals can be met.
Apr 05 Richman, Steve Years ago, a pair of index fingers was all that was needed to set your CG. Today�s high performance ships will need a precise setting of CG. The #69 3054 Multiplex CG tool at $42 can do the trick. The max capacity is 10 kg (22 lbs). CG range is 30 to 150 mm.
Apr 05 Ciurpita, Greg The relationship between flying speed, the depth of a wing and Reynolds No. is graphed with the appropriate equation considering air viscosity and density. Another equation & graph relates model wing loading to the coefficient of lift, Cl, and airspeed.
Apr 05 Drela, Mark A study of sheer load in the spar of a wood wing is discussed. A truss structure is very effective but has a high part count. Sheer webs are practical alternative. Vertical shear web grain, if it is stronger, may be true due to its adhesive bond to the spar cap. If the rib is split it should be securely glued to the sheer web or the wing will be weak. Avoid holes in the sheer web. Reinforce any required holes.
Apr 05 Vasgerdsian, Greg The Hobbie Hawk design is over 20 years old but is a favorite model of many modelers. It was ahead f its time. A robust design, it came a number of sizes up to a 10� span. www.hobiehawk.com carries the story and pictures. Designed by Hobie Alter, a sailboat manufacturer, 10,000 to 14,000 sailplanes were sold.
Apr 05 Register, Dave Dave Describes how to cut a highly tapered (2:1) foam core wing using a cutting bow and a drop arm foam cuttger. The bow should be 2X that of the core in length. Instructins for getting good results. Template plotting software available from http://myweb.cableone.net/regdave/index.htm
Apr 05 Nagel, Tom Torey Pines and other California flying sites are described.
Apr 05 Kuhlman, B^2 Alexander Lippisch designed early gliders including flying wings using models vs. wind tunnels. The Storch and Delta series were the result of his work. The Storch I (1927) The Storch IV is shown in 3 views. It was launched by a bungie cord and hand tow.
