I have found the IMAC site with the charts of the different maneuvers. But I can't find a chart that explains what each different flight symbol means. Can someone help me out here. thanks.

Try the following link to the full scale site for descriptions:

EXCAP232

Thanks, thats a lot of what I was looking for.

Also on the IMAC site is a Judging guide, and it has ALL you need to know about the box, the maneuvers, the downgrades, and the Aresti symbols....It has excellent drawings to display various aircraft attitudes, tracks, and geometry of maneuvers...

AN indispensable source if you want to know what it's "supposed" to look like.
