I’ve made a helicopter before (see this previous post.) I made the same helicopter balloon again, and then added two additional features.
First, I added tail rotors made with a 160 balloon. They are just like the main rotors, just smaller.
Second, I formed the cockpit using a small clear 260 balloon. I also put a small ball (with some pictures of faces attached) in the balloon, just for fun. I’ll have to find some little toy people to use for purposes like this!
