Issue Contents:
Making efficient turns in thermals is important to surviving light lift at low levels. Use of 1 or 2 sticks to control the turns is discussed.
Rob Glover becomes the 100th LSF Level 5 flier ever. Follow his 8 hour slope flight at Brookville Dam in Alabama. Six pilots teamed together to achieve the long flight. Ed talks of his dealing with this task and the models he used. It was 18 years after level IV to do this flight.
TopoZone.Com provides topographical maps receives honor of being the best site for topographical maps on line. Internet Explorer doesnt work as well as Netscape. Several sites were located on this page and the information was quite helpful. Print or save views for future use.
Comments about park fliers and slow flyers becoming a good way to get new members into RC clubs. These models are particularly well suited to kids The slow fliers can be used to find and use small pockets of lift. Light air slope soaring opportunities fit these fliers.
Eastern Iowa Soaring Society Spring Soaring/electric Contest winners Iowa Aviation Museum has a Curtis Robin Mark plans to replicate in scale.
Dymond Modelsport USA was visited and a report made about the wide range of products in stock and available from this multinational company.
A review of airfoil polars what they say and how to use them. Cl Cd Lift Drag Lift vs angle of attack Reynolds numbers Moment Coefficients.
The FMA Razor is a foamy with a speed 400 motor. The foam is Arcel and is not Styrofoam or EPP. It takes paint and glue directly. Better abuse resistance. Flight performance is good with 600 ma batteries. Gordy evaluates larger batteries. Comparisons with Zagi.
Part 2 of series on swept wings and dihedral. Yaw-roll coupling enables a designer to make a stable aircraft. Aileron drag is less than induced drag caused by different angles of attack on R L wings. If the vertical stab is too big the model will turn into sideslip. Smaller V. Stab increases spiral stability but harms directional stability. High dihedral causes roll problems in x-winds. Dutch Roll oscillation.
Instructions to help new interests evaluate XC. The Sailplane a team a vehicle and lastly equipment. Good source of information on the subject.
A Shakespeare Wonder Pole is a 4 section fishing pole that makes an excellent stand for thin magnetic or Mylar tape to study the wind activity.
Mark suggests making up labels to be placed on kits at a local hobby show with an offer to help the purchaser learn to fly the model and join a club.
