The plane is one of many to be displayed Saturday at the club's open house, which will be from 1 to 4 p.m. at the club field on Jackson Road in Clay Township. The day will include radio-controlled aircraft displays and demonstrations, as well as instruction for first-time fliers. To get to the field, take Route 38 north to Mahood Road.
