Rc glider Flaps vs. spoileron landings.
When pointing up against the wind, aply and work the flaps or spoilerons and just wait until its down.
For flaps gliders you can dive down, but with spoilerons you have to keep the speed down on the landing speed, if you dive it just accelerate and you will feel that the spoilerons dont work at all, and it will overshoot the landing spot.
If you are on a slope with a turbolent top, then land down in front of the slope, or walk backwards until you can feel a staydy wind, (around 150 200 feet) and land there.
We do that on a very steep coast slope at the west coast, if you dont do that its 90 % sure that you will crash.
Good luck
