More than 40 Tulsa pilots flew some model planes Saturday afternoon at Muskogee's Love-Hatbox.
Pilots from the Three Rivers Area Model Plane Society are spending the next two days flying the models and sharing their hobby with others.
Organizers say there is a lot to learn from their club.
"We teach them things about planes, how to build planes, how to fly planes and even how a plane flies," said Three Rivers Area Model Plane Society Club President Jeff Andrews.
This is the club's 15th annual fly-in.
You can stop by and watch them fly the models Sunday from 9 a.m. to 4 p.m.
