Stealthy, aerodynamic and able to cruise at fairly slow speeds, the OmniCruiser is a modified version of the Turbo OmniScimitar made with an emphasis on slow speed glide performance.
The development of the OmniCruiser was initiated to produce a new derivative of the Omniwing series with performance catered to lower speeds after many variants had been specifically designed for faster flight (including the mostly unrelated and considerably more advancedOmniwing Swift). The design's configuration eventually settled on a cut down version of the Turbo OmniScimitar with the center of lift moved and the overall weight of the aircraft reduced. Flight testing showed the aircraft an able cruiser, so it was approved for publication.
TAA USAF Designation: F3-1F2
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. 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
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.
Begin measuring the vertical fins' edges by finding the point 0.75 inches ahead of the trailing edge along the wingtip and make a marking it on one side as shown. 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.
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.
Step 4: Cutting the Trailing Edge and Taping
Measure 1 inch forward of the center line mark you made previously and make a new mark. From this point, make a line connecting this new mark to the edge of the fin. Cut along this diagonal line to separate what will become the counterweight later.
Cut the vertical fins along their diagonal lines as shown in the sixth and seventh photographs. After doing this, fold them along the lines parallel with the center crease on one side. Repeat this on the other side.
Once your OmniCruiser's vertical fins have been folded down, apply tape where designated in the photographs.
Step 5: Making and Applying the Counterweight
Take the triangle you cut off previously and cut along the diagonal line that bisects it. You may discard the small bits of paper and focus your attention on the new isosceles triangle you have created. After laying it down flat, 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 as seen in the seventh photograph.
With the counterweight itself made, it is now time to mount it. Flip the airframe inverted and tape the counterweight to the bottom of the airframe at the leading edge. This will complete your OmniCruiser. .
Step 6: Flight
The OmniCruiser flies similar to other designs derived from the OmniScimitar, albeit at a slightly slower speed; any origami aviators familiar with previous Omniwing types should have little difficulty working with the OmniCruiser.
Launch should be at moderate speed at a neutral or negative attitude, with the airplane being held by 3 fingers (1 over the wing, 2 beneath the wing). This type of launch will give flights a good glide profile. Test flights should be conducted to see if any trimming is necessary. Additional applicable surfaces include rudders, spoilers, spoilerons, elevators, ailerons, elevons, and air brakes. Enjoy!
