The Gulp was evaluated for dynamic soaring without fear of messing up aglass ship. Get the Gulp from Steve Drake at stevedrake@aol.com
Wizard Compact 2 by Milan Janek in Slovakia is an ARF. 100″ is small enoughfor local hills large enough for larger ones. It is built tough for the had landings at slope sites. Airfoil is SD2030 and is suitedfor F3F.
History of low-speed low RN research touches on many individuals includingEppler Somers McReady Selig Donovan Drela. Tom Clarkson has helpedmake the code available and usable to modelers. An actual andtheoretical CL/aOA polar is shown and discussed for S6063 used for DLG.X-foil code used. The problems with bubble control is discussed.theoretical CL/aOA polar is shown and discussed for S6063 used for DLG.
The DAW Mustang has a cloroplast tail that is known to fracture at lowtemperatures. A modified design with carbon fiber rods added to tail.The rods fit into the corrugated holes in the plastic tail. Thetail has to be laid out with the corrugtion running parallel to fin LE.
Snowboard cases make great carrying cases for models. Sportube doublesnowboard tube provides all the space needed + wheels. It expands!
Plank vs. swept wings are discussed. Which is best depends on the kind offlying being done and the skill of the builder. Swept wings have moretwisting and bending loads. Winglets may not be helpful on a sweptwing design. Swept wings must have part of the wing not contributing liftso efficiency of w plank may allow higher wing loads but reflexof 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
Comments about Los Banos 9th Annual Scale Fly-in which is 1.5 hours drivesouth of San Francisco Bay off Highway 5 and 152. Jerry is glad to be back in CA where he can pick up slope soaring again. Large scalemodels shown ASH-25 ETA TG-3 K-6
