Central Illinois Aerospace is a model rocket club with monthly meetings. Their meetings take place at the Springer Center in Champaign. They usually have two launches per month, usually at Dodds Park in Champaign. In the late fall and early spring, they try to have their launches in Rantoul or Monticello since they have more airspace there.
They have about 50 members but the attendance at the monthly meetings and the launches vary. When it is a nice day, the attendance at the launches are very good. They do have a web site with a lot of pictures and videos of their launches, which is at CIARocketry.org.
