Put some small eye hooks in and secure them with rubber bands. Pack the foam tight around them and stuff them in place, use popcycle sticks and glue the sticks in locations that lock the items in. Use styrofoam and pack it in around the item to hold it in place. Use velcro and put them where you need them to secure the item.

What ever way you do it remember to use the battery and rec. to get your final balance and be sure that the rec. is behind the battery.
ENJOY !!! RED
