Yes, there was control line flying at for all ages at the KidVenture section of EAA's AirVenture 2025 Oshkosh. Over 1000 flights were conducted during the week. I am attaching a couple of photos.
PM me if you are interested in volunteering next year - you get free admission when you volunteer.
If you are interested in the electric plane that we were flying, more information will be posted soon at
