For over 40 years, the Central Pennsylvania Aeromodelers Association has been hosting the largest one-day RC Expo in the country ! Each March it is held annually at the Lebanon Valley Exposition Center and Fairgrounds in Lebanon, PA. (only 20 minutes East of Hershey, PA.) Two RC clubs from the area combine to create the CPAA. The Carlisle Aeromodelers Club in Cumberland County, PA and the Lancaster County Radio Control Club in Lancaster County, PA. These two clubs work throughout the year planning this huge one-day event that brings RC enthusiasts from as far away as Connecticut, New York, Ohio, Maryland, Delaware and Virginia. Each year approximately 3000 people enjoy a day of buying and selling RC models. Plus hobbyist swapping stories and telling tales is found everywhere in the convention center. If you contact us, please know that emails are checked weekly and will be responded to as soon as possible.
