The Cozy IV was very acrimoniously cloned by another company, who supply kits of parts to assemble, but the Cozy can be scratch built, although there are some companies supply some of the trickier parts, like the landing gear bow, and the engine cowl - mine has the carbon fibre cowl, whicj only weigh about 8 pounds each.
