FROG stands for ‘flies right of the ground’ this plane was just on the TV. The body was aluminium and the wings and tail were made of paper.
This was made in the 1930’s? You put the body of the plane in the box with the propellar attached. There is a handle on the front of the box and a mechanism that holds the propellar. You turn the handle and it winds up a rubber band. Then you peg the wings and tail on and let it loose to fly up off the ground.
Our forebears may not have had the Internet but they knew how to have fun!
