I've added a new rocket to my Free Stuff page. It's the 13 mm Pinwheel. It's quick and easy to build. It flies well in small fields and spins like crazy.
I'd appreciate feedback from folks who build and fly them. I will offer low cost 18 mm, 24 mm and possibly 29 mm kits soon so please don't abuse my generosity (and the copyright) by up-scaling or cloning without my permission.
