The Kirkwood Mall was filled with planes and people Saturday for the Bismarck Aircraft Modelers convention.
They hold this convention every year so people can show off the planes they've created.
They range from the size of your hand to over 6 feet long.
Model planes can cost between 200 and 6 thousand dollars.
Today there were about 40 planes for people to see.
Brandon Cook of Bismarck used to race cars, but now he's flying planes.
He says anytime the wind is below 15 miles per hour, there is someone out flying their model airplane.
"We have a yearly mall show to bring awareness of the hobby. We're out here to help if anybody wants to learn how to fly. We can teach you how to fly too. you say you want to learn or want to join we will take you up in our own club trainers or one of our personal trainers and we will teach you how to fly," Brandon Koch, president of Bismarck Aircraft Modelers said.
The group is holding a flying demonstration the weekend of June 13th at Hoge Island for anyone interested in learning more about model airplanes.
