Have you ever tried dynamic flying to mountains in Switzerland, like Chasseral or Creu-du Vent, they are very famous there
It is desirable to arrive on a slope with an angle of approximately 45° to the terrain, so that rapid movement away from the slope is possible in the event of a problem (high fall rate or turbulence). During flight along the slope, a drift angle is necessary in order to counter the effect of the wind and have a ground path parallel to the slope and slightly clear on the valley side to avoid getting too close to the slope or, if you fly above the ridge, to avoid going over the summit in the downdraft. By remaining in this very buoyant zone, the glider will be able to remain in the air for as long as this dynamic condition lasts. Do not fly on the ridge or below the ridge on the downwind side. You must have a sufficient indicated speed, and not hesitate to increase it in the event of turbulence.
In the past, in the 90s, I did quite a bit of flying there in the RC version, with ASW, Discus and Cirrus coming from (Graupner)
But sometimes the breakage quickly became expensive!
Yes, I already tried. This method is good for long-time flights, but difficult to use for long-distance flights, i think.
