Fast, long range and simple, the Omniwing is a stealthier variant of the Proto-Omniwing paper airplane. Its balanced design allows it to fly quickly whilst also retaining the ability to fly fairly slow if desired as well; this makes it an excellent trainer. In addition, the design is simple enough to allow further development easily.
This variant of the Proto-Omniwing was originally designed in December 2009. It has proved so successful that it has been used as the basis for every other "Omniwing" variant since, including the Super Omniwing, OmniScimitar, Turbo Omniwing, Turbo OmniScimitar and Manta flying wings.
TAA USAF Designation: F3-1P
Step 1: Materials
1 Piece of 8.5 by 11 inch paper
Step 2: Width, Fourth and Corner Folding
Fold your paper in half along its width. Once you've done this, fold the edges of the paper back in to the crease. Then fold the corners of the paper into the crease of the outer fourths as shown. Then fold the diagonal edges back, and the folds on each side should now touch the center crease.
Step 3: Leading and Trailing Edge Preparation
Fold the tip of the nose down to the vertex of the previous leading edge folds. Then pull the leading edge back so that what was the blunt tip of the nose touches the center crease and repeat on the other side. Then fold the paper in half so that these folds are on the papers outside.
Measure 2.5 inches in from the trailing edge along the center crease, make a mark and then measure 2.5 inches outwards from the center crease along the trailing edge and make a mark. Then connect the two marks.
After you have finished measuring what will be the counterweight, begin measuring the vertical fins. Find the point 1 inch in from the wingtip along the trailing edge and make a mark. Then from this mark measure 1 inch in and make a line and a mark. Then along the wingtip, measure 0.75 inches forward from the trailing edge and make a mark. Then connect this mark to the one you just made.
Cut the counterweight triangle off and cut along the diagonal lines of the fins. Once this has been done, tape the airfoils as shown.
Step 4: Counterweight Folding and Application
Take the piece of paper you trimmed earlier and unfold it. Fold the corners inwards on each side. Then pull them backwards and make a crease. Then pull the bottom layer backwards as shown. You should now have a smaller, denser triangle. Flip the airframe inverted and tape the counterweight to the bottom of the airframe at the leading edge. This will complete your Omniwing.
Step 5: Flight
The Omniwing is a fairly simple airplane, and requires very little instruction to fly correctly. Launches should be done at moderate speed at a negative or neutral attitude, with the airplane being held by 3 fingers (1 over the wing, 2 beneath the wing). This type of launch will give flights the longest range at the best speed. Additional applicable surfaces include slats, rudders, spoilers, spoilerons, elevators, ailerons, elevons, and air brakes. Enjoy!
