RC Soaring is flown by different classes of sailplanes or gliders. These aircraft are towed aloft by 12-volt electric winches. They have no other form of propulsion. The winches have a great deal of power and, depending on the aircraft, a launch height of 500 to 600 feet can be obtained. Competitors fly in rounds. Each round has a different task associated with it, and each has a flight task and a landing task. Most flight tasks are based on some form of precision flight time (seven minutes, plus or minus, from the time of winch line disconnect to contact with the ground). The closer the landing is made to the target time, the more points are awarded. Landing targets an exact spot; the closer to the spot, the more points gained. Typically, 10 sailplanes will launch at the same time. Sailplane classes are divided by the size of the aircraft. Smaller aircraft can fly in classes allowing larger aircraft. The winner is determined by the total number of points obtained.
In our final episode of Nats Demystified, Matt Ruddick talks to Wally Adasczik and Bob Sifleet about hunting thermals in Soaring and Free Flight events.
Join Matt Ruddick for another Nats Demystified where he talks to League of Silent Flight Secretary John Marien about how sailplanes are able to soar in windy conditions.
In this episode of Nats Demystified, AMA's Matt Ruddick talks to League of Silent Flight President Wally Adasczik about sailplanes, particularly about on way these aircraft are launched into the air without the need for a propeller or tow-plane.
