Narrative:

During a low pass at parks college (over the runway) another plane was making a downwind approach. Evasive action included maneuvers considered aerobatic at less than 1500' AGL. Problem arose from making passed down the runway mixing no radio and radio aircraft (additional passes also included banks possibly exceeding 60 degree). Corrective action would include better ground and air control at planned events and preflight planning with no radio participants.
