This glitch is only viable ~ patch 3.0 to 5.0.

Guide:

To do this, stand on a ledge or decent slope, build a foundation the is higher than head height one foundation away from where you want to launch/ cliff edge. Select the next foundation, ensure you are inside the build and near a ledge. The structure will push you out and you can then deploy your glider to go massive distance at the fastest speeds I know of so far.

Best locations I know so far:

Eastern wild island to get to north desert/sanctuary no 3 or duneshelter.

Hill of beginning to get pretty much anywhere.

Sea breeze archipelago to get to fisherman’s point or sanctuary 1.
