SLOPE SOARING PAGE

Slope soarers use the vertical component of a wind as it is forced up and over the slope of a hill.

This means that the type of model that can be flown depends on the strength of the wind. In very light winds thermal models may be best suited , whereas in stronger winds you need stronger, heavier built models which in extreme cases may have to have extra weight added in the form of lead ballast

DYNAMIC Soaring

Dynamic soaring was developed in the USA and goes completely against the grain of most peoples understanding of slope flight. To fly on the backside of the slope where there is little or no "lift" seems illogical. The requirements are either a fairly sharp ridge, or a sudden drop at the back of the slope. Loops are then flown in this "dead" air, with the aircraft accelerating every time it meets the airstream coming over the hill. The stresses on the models can be enormous and the fastest speeds are being clocked by purpose built models mainly of epoxy fibreglass and Carbon fibre. Despite their strength, even these models sometimes succumb to the huge stresses.
