Four ATOS pilots have signed up for the Quest Air Open National Championships.
This is the first time in a long time that we have had more than a couple of
rigid wing pilots flying in competition here in US (it's common in Europe), and
certainly the most since we held the Class 5 World Championships here at Quest
Air in 2006.

If you'd like to compete with your rigid wing sign up soon for the Quest Air
Open National Championships as the slots are filling up fast (no fooling).
