I have noticed that some of the flying stands at the field are in need of a bit of repair. To help any one who might wish to contribute, google found some plans for me.  The files attached are variations on some standard versions. 

The one with angled side legs and similarly sloped wing stops, overcomes an issue found with the tables tipping forward with large planes or lots of thrust.

If you decide to build one or 2 choose the version you like best.  Most people use Pressure Treated Wood.  If using wheels, watch for lawn mowers on garbage day in your neighbourhood and select the one with the largest wheels to be the donor.

The Run-Up-Stand-Normal seems to be very popular and very close to the AMA approved version.

The first one is a variation of the Run Up Stand-Normal to correct the tendency for it to tip forward with larger planes or heavy weights on the side tables.

You may wish to make a variation which is smaller or larger to accomodate the size of planes you have.  The things you might change are the distance between the uprights that act as wing stops, the angle of the legs to resist tipping and the overall height of the table.

Side tables can optionally be at the same height as the table or set lower as some planes show.
