Introduction: How to Make the Turbo Omniwing Paper Airplane

Very fast, long range and simple, the Turbo Omniwing is a faster version of the Omniwing, (itself a development of the popular Proto-Omniwing paper airplane), with some structural improvements for high-speed flight. The Turbo Omniwing was designed to have performance similar to the UltraDelta, but with a simpler airframe, comparable to that of the OmniScimitar.

Educators could easily use this versatile paper airplane to demonstrate:
  • Glide ratio
  • Hangtime versus other aircraft
  • Weight and balance
  • Flight dynamics
TAA USAF Designation: F3-1Z

Step 1: Materials

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

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. Once you have done this, undo the last folds and fold their edges inwards as shown. Then restore the leading edge folds to cover these last folds.

Step 3: Leading and Trailing Edge Preparation; Airfoil Taping

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. Cut along this diagonal line.

After you have finished measuring and cutting what will be the counterweight, begin measuring the vertical fins. Find the point 0.75 inches ahead of the trailing edge along the wingtip and make a mark. From the wingtip measure 1 inch in and make a mark. Then from this mark, measure 1 inch inward (perpendicular to the trailing edge) toward the leading edge and make a mark. Then connect this mark to the one you just made on the wingtip. Then cut along this line.

Apply tape to the trailing edges of the airfoils to secure them. Once this is complete, the airframe should appear as it does in the last photograph.

Step 4: Counterweight Folding

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 Turbo Omniwing.

Step 5: Flight

The Turbo Omniwing's performance is comparable in some ways to the OmniScimitar and in others to the UltraDelta. Launch should be at moderate to high 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 and/or best speed. Additional applicable surfaces include slats, rudders, spoilers, spoilerons, elevators, ailerons, elevons, and air brakes. Enjoy!

The instructions for flying this plane are not very clear. Two fingers underneath and one on top? How do you throw/drop/launch? Some more pictures would be helpful.

The Turbo Omniwing should be held similar to this pictured OmniDelta, with two fingers over the dorsal (top) side of the paper and one finger below on the ventral (bottom) side at the center of the airplane. The Turbo Omniwing should be held with its wings paralleling or slightly angled toward the ground. When launching it, it should be advanced forward through the air then released.

I believe the pictured Turbo Omniwing may have its fins folded the opposite way as they should be. The fins and airfoil folds should each be on the dorsal side of the aircraft while the counterweight hangs below on the ventral side. The fourth folds should bend upwards toward the fins and airfoil folds when they are positioned correctly. Simply reversing the fourth and fin folds should be sufficient to remedy these issues (do not bend the airfoils while reversing the fourth folds however). :)
