The Blue Skies of Earth - S1.E4

Yungstar's flying antics keep getting him into trouble in front of his rival Aero. Eventually, he leaves camp to tend to his bruised ego and flies right into the Rulon army. Hammerhead has created a large airforce for Krulos that includes the world's largest Pteranodon. Somehow, Yungstar must return to camp and help the Dino-Riders' new air trainees defeat this new threat.
