We built our own "bat" toy today… in other words a rubber band powered flying toy. We stumbled upon a kit at Cracker Barrel actually for just a couple dollars (similar to this one). It is fairly fragile and required glue after about 10 flights… but the general premise is fun. Bug can’t wait for it to dry to take it outside again.

UPDATE: It has withstood about 2 more hours of play this afternoon. Good intro to planes for a couple bucks.
