You can use anything for an airplane as it's function is just to hold the motor and look cool.
The following website provides some really neat planes that can be made from cardboard in black and white and color. I chose the Spitfire.
Attach the motor to the plane. I used a cable tie to do that.
Find a toy propeller from one of those broken airplanes we all seem to have and attach to motor shaft. I drilled a shaft size hole in my propeller and attached with super glue.
Then you must attach the plane to a boom approximately 4 feel long and of any kind of material.
I used a piece of hollow fishing pole. Again I used zip cables to attach the plane to the boom.
Run the two wires from the motor inside the boom (or outside if you wish).
