Slope soaring is another exciting aspect of this hobby. Here the pilot stands overlooking a steep and high slope, then launches the model by hand into the updraft caused by wind impacting the face of the slope. Flights of several hours are routine off the slope due to the generally unlimited lift conditions. Models of all types can be used for slope soaring, including thermal duration models. During high wind conditions specialized models can be used for racing and to perform impressive aerobatic maneuvers. Scale models are also popular at the slope since their beauty can be appreciated by slow fly-bys and scale-like aerobatics.
