I'm sure someone will help soon on the link.....
It's really straightforward... Pump up while moving backwards, recover that same ground by gliding or slow fall in the inverted position while walking forward.This allows you to fly in a small area instead of needing a football field. So if you take 10 steps backwards, work on trying to recover that same 10 steps and end up where you started. It's all about keeping the sail loaded with enough and proper pressure to achieve what you need.
In the start for me, I stuck with simple up and down until i got the motions correct...then i moved towards figure 8's..then tricks and ground play antics........sweating and smiling the whole time
