Good news: you don't need an aviation license to fly these airplanes! These lightweight foam airplanes are great fun for kids. They come unassembled so kids get to put them together before they fly. They do glide really well, but they are delicate and break easily. (PLEASE remember to add the included clip to the nose of the glider or they do not fly!) NOTE: These foam gliders are really inexpensive and in our tests kids really thought they were cool even though they tend to break apart with use!
Foam airplanes are 4 1/2 - 5 1/2".
