While every organization has its own rules, Hero Airs and Hero Xtras are allowed in every competition in the United States. The AWI, UFO, USDDN, IDDHA, FDDO, Skyhoundz, and the Quadruped all allow these discs at their competitions. The Quadruped ONLY allows these two Hero discs. The other mentioned organizations* currently allow all other Hero discs except for the Sonic and the Pup, but we are working diligently on getting the Sonic approved for all organizations. *The AWI allows ALL Hero discs at their events. Note: these guidelines are for large scale, National and International competitions. Smaller, local competitions leave the allowed discs up to the event organizer, so if you want to use a Hero Sonic or Pup, in a UFO Local for example, check with the event host.
