This new category originally was named AR Drone 2 Custom Hull. Starts from now I change it to "RC Projects". Just like the name this category will hosted many RC (Radio Controlled) projects from aircraft, boat, car or even robot, with different kind of materials not just paper, can be foam, wood, plywood, plastic, etc. I begin with this RC plane Extra 300. I use 2 kind of materials which is 3 and 5 mm foam sheet, it's familiar with the name depron foam, but in where I live it is called "polyfoam". The 2nd material is 3 mm and 9 mm plywood. The design process of this foamy RC plane is pretty similar from designing a papermodel or papercraft. The build process is also similar.
