How to Make the OmniDelta Paper Airplane

The OmniDelta is a fast, long range flying wing paper airplane with a moderately swept delta shape.

TAA USAF Designation: F125-1

Step 1: Materials

Required:
1 Piece of 8.5 by 11 inch Paper
Tape
Scissors

Optional:
Pencil

Step 2: Width and Corner Folding

First, start out by folding your paper in half along its width. Then pull the corners down to the center.

Step 3: Nose and Corner Folding

Pull the nose down to the bottom of the corner folds and then make a second set of corner folds that reach to the center.

Step 4: Make the Vertical Fins

First, start this step by folding your OmniDelta in half so that the airfoil is on the outside. Then make a cut roughly 3/4 of an inch in from the trailing edge that reaches about 3/4 of an inch into the wing. Then unfold the wing and make a cut down the center line so the two fins are separated.


From here, fold the fins out, with their trailing edges meeting those of the wing, insuring their straight alignment to the center line. Once done with this step, the fins should be pointing straight up.  

Step 5: Taping

Tape the two airfoils down at their rears as shown.

Step 6: Flight

The OmniDelta is very fast for a flying wing, and is moderately difficult as a result. At launch pitch the nose down, give a moderately fast advance forward and release.

For long range flights avoid stalls, because the OmniDelta is very rarely able to pull out of even a 35 degree dive at 15 feet.

Step 7: Modifications

One modification I've made is the:

NF125-1 Cross Control Demonstrator (CCD): An OmniDelta with control surfaces for demonstration of cross-controlled (uncoordinated) flight.

Although I've only made one modification to the airframe myself, I know there are more ways to reconfigure this craft.
