I've developed, in conjunction with High Energy Sports Inc., a new
style hang glider swing seat harness. After the first testing I made some
changes and this video shows some flights with the new harness at Dockweiler
Beach, CA.

In the early years of modern sport hang gliding basic swing seats were used for
most of the flying. But as the sport advanced, the use of prone position
harnesses became the standard method for pilot position in hang gliding. I
always liked the seated position better and flew that way all through the
1970's. Now I'm working on a return to that original method with some modern
designs for the seat itself and a set of aluminum bars to adapt the glider's
control bar to the seated position in gliders already rigged for prone flying.

Frank Colver is re-inventing the seated Position for hang gliding.
The advantages of "seated adapter bars" as opposed to what we did in the good
old days is this. Better flare authority, increased speed potential, and no
rigging changes to a glider rigged for the prone position. The base tube remains
far forward so the speed potential is increased as opposed to the "rigging
changes" we performed in the good old days by moving the control frame rearward.
Frank is also developing a new swing seat harness in conjunction with High
Energy Sports.

Of course, we've been using various versions of adapter bars for
seated flying for quite a while now.
