i do a little bit on D/S with my small hlg

i have a small 30 inch DLG that i fly in a school yard and along the edge of the property there is a large length of popular trees on top of a small slope

i usually try to soar the trees as ridge lift and fly threw the rotor to land but on many differant occations i have found the lifting part of the rotor and im able to fly several lengths of the tree line [on the backside] if im tucked in close to the treeline

what i have found however,that the ridge lift in front of the ridge offers better ,,secure ,more stable ridge lift so i tend to only try D/S as im baling out to land BUT im hoping to go over the back and dive down into the rotor soon and start the D/S generation happening [if that makes sence ]

the ridge im refering to is manmade so it is very straight and so is the tree line so i have been able to soar parallel with a fairly predictable rotor BUT as the air gets colder and these effects gets greater ,,,i loss the leaves from the trees and the rotor is not as defined

i realize that you are refering to a somewhat differant form of D/S but im experimenting until i get the balls to go over the back with lots of speed!

maybe foam is in order

cheers j-coles

You can DS anything that creates a shear layer. I've done hills, mtns, road cuts, trees, houses, RV's, etc. Of course a little lift makes things so much easier to get going.

High Moutain sites are my favorite. My main DS hill is above 12,000 feet. Thin air makes any plane fast! No trees up there but lots of rocks and snow!
