The pitch of the propeller causes this noise.

Check out the Instructables website and type in "Propeller-Powered Car" on the search window. The instructions for it will come up along with a video.
The way you make an elastic powered propeller is to wine a propeller to a twisted elastic, let go and enjoy!
You type in ooo.

propeller
A uni-rotating propeller is one that can go around in both directions. This type of propeller typically will do different things depending on which direction it is going.
It could make a grinding type noise when moving slow. A "whirrr" type whine when moving faster. The grinding noise may change to a clunking noise when turning the wheel. Any of these noises means "fix me now or else."
The rotor is like the engine to the propeller. A propeller is the fan like blades on the top that spin to make the helicopter fly.
