Propeller
Wallace R. Turnbull invented the variable-pitch propeller.
If you mean "the first plane that had a motor and propeller, and could fly" then it was the Wright Brothers. If you're not worried about the thing being able to fly, there were LOTS of guys who made propeller planes that couldn't fly.
Well first, u have to go and get a propeller off of something. Then you should go and glue a couple of pieces of popsicle sticks then get an axel and put wheels on it. Then get rubberbands to put the propeller on.
