You can see the new wheels distinctly in the video. They turn fine
in fine sand. You can find them here:
Raven Hang Gliding, Inc.
These are the eight inch variety.

After I landed out (after the second tow) I was able to haul the glider out
keeping it on its wheels. So they came in real handy today.
