Made from cardstock, mylar and a 'used' RC motor assembly, this flying saucer is moderately easy to build and fun for experimenting and creating UFO sightings in your neighborhood!

Step 1: Scale and print out model

Download the file and save to your computer...open it with "SolidWorks eDrawings" for viewing CAD drawings.

I scaled mine 1 inch to 8.75 inches in order to fit the largest piece on one sheet of cardstock.

Step 2: Cut tabs for support members

Cut tabs and alternate folding left and right to support outer skin

Step 3: Join cutouts

Use rubber cement to join cutout card stock frame members

Step 4: Skin the saucer

Picture of Skin the saucer
Skin your flying saucer with mylar foil in alternating silver and gold, clear, etc. Use rubber cement to join the mylar to the support tabs. This is the most difficult part of the assembly!  1/2" wide clear tape along the seams will help make the cover smooth.  (If you use a big enough motor you can use card stock for the skin and avoid wrinkle issues you may have with mylar!)

Step 5: Install motor and propeller assembly

Picture of Install motor and propeller assembly
Install your motor/propeller assembly atop the solid paper circle with the propeller extending above the framework. Mount with clear adhesive tape and/or glue. Install a circular 'duct' above the 'saucer' to direct air downward. There should be space between the bottom of the duct and the saucer 'skin' as well as between the duct and propeller tips. (doh!)

Step 6: Install 'flaps'

Picture of Install 'flaps'
Install elevator control to a single base elevator to give forward control movement.

Step 7: Test fly your saucer

Picture of Test fly your saucer
Test the saucer and make adjustments as necessary adding 'rudders' to control rotation and/or left/right elevator control. (This will require a larger motor/propeller assembly to handle the extra weight of servo and control assembly but should be doable,)

Step 8: Freak out your neighbors!
