The video is of the Elmira Aerotow 96. This is a great way to evaluate theEvent and scale soaring.
Mathematics of high starts is discussed. Products available and potential for launch altitude and breaking the wings. Assembly instructions.
A semi scale DG-200/17 is now available for $239. Kit has epoxy glass fuse with CF reinforcement. Veneer sheeted fiberglass reinforced foam wings.
1/4 scale DG-600 is now available from Mark Foster. Also available is the DG-300.

High quality packs available from Hangar 9 JR 351 servos with brass gears has low slack and only .5″ thick. Transmitters and Receivers.
Brian linked up with Australian modelers before his trip there. He was able to fly on several splendid beach bluffs. Photographs
One cannot take the balance point of model and apply it to another model with the same airfoil without knowing wing planform and tail layout.
Photo of Jim Armstrongs Spirit piggy backed on a Telemaster fitted with skis.
Tubular wing spars are described which dramatically increase the strength of foam core wings. Long tubes are fit into cores. Bend in joiner rods.
Lars tells us of how the internet is of value to sailplaners. References to RC Soaring Exchange (RCSE)
A good slope include Access Consistency of wind and Topography. Bill finds a new slope using maps. What things to take with you to the slope.How to assemble your hiking pack and attach your model to the pack. dont let things hang below. Result is that a beautiful site was used.
Lehman and Dvorak previously debated use of power plane and glider for training. A case is made for training on full size gliders.
Robin recounts the progress to highly efficient models used today in scale soaring. The modern prefabricated model offers much despite the price.Issues you need to consider to evaluate their use of a scale model Issues include Price Appearance How you might launch fly your model.
A vacuum bag frame is described for making small parts. It aids in ease of final assembly. PVC pipe is used.

Hans-jurgen Unverferth is a prolific designer of tailless aircraft. His work is discussed in an interesting way. Despite high L/d ratios FW havehigh sink rates because they fly faster. Hans-jurgen is testing RC systems to move the CG and achieve improved flight performance.
Tape Hinges can be made using double sided tape and a tape to cover the sticky surface where you dont want it to stick. Diagram shown.
Molded hollow core wing construction Pt. IV talks about selection of the substrate for making the skins. Spider foam cut into 1/16″ slabs was used.
