Introduction: How to Make the Killer Owl Paper Airplane
The Killer Owl is a fast, long range, durable and extremely stable paper airplane. This airplane can go fast, and it can also fly very slowly if you want it to. The Killer Owl is an advanced variant of the Super Owl. With its new winglet arrangement, the Killer Owl has skids that always keep the plane level upon landing. It is also able to have more control surfaces added.
This instructable covers how to construct the two different Killer Owl airframe types.
TAA USAF Designation: A73-2 (with winglets);
A73-2A (without winglets)

Step 1: Materials
1 Piece of 8.5 by 11 inch Paper
Step 2: Length and Corner Folding
Take your paper and fold it along its length. Then pull the corners in and fold them into the center.
Step 3: Nose Folding
For this step, you will need to make more intricate folds. Begin by pulling the front tip of the nose down to the bottom of the corner folds. Turn the paper over and then pull it into the center again. Then flip the paper again, which should now appear as it does in the last photograph.
Step 4: Tucking the Nose
First, pull the bottom half of the diamond up to its front. Then open your folds from the previous step. Proceed to fold the triangle that was the diamond back into the folds of step 3. Then fold the corners in again as shown.
Step 5: Wing Folding
At the same height of the front triangle, (or about an inch above the bottom of the fuselage), fold the wings down. While doing this, keep the wings from having any chord by aligning their trailing edges with that of the fuselage.
Step 6: Make the Ventral Fins
First, measure 1 inch in from the wingtip along the trailing edge. Then measure 1.25 into the wing from the trailing edge, and make a line to that point from the trailing edge as shown. Use your ruler to then measure along the wingtip, one inch from the trailing edge. Then cut in between the point on the wingtip and the point 1.25 inches into the wing.
Step 7: Fold the Ventral Fins; Make the Winglets
Fold the ventral fins so that their trailing edges are parallel with that of the wing.
Optional (For the "-2A" version):
Fold the ventral fins up to the bottoms of the wing and then fold the wings down. Then fold the wingtips up so that their edges meet the ends of the ventral fin cuts.
Step 8: Taping
The Killer Owl is indiscriminate when requiring tape. Both airplanes have common taping points. Tape the plane at its front and back, and then across the wing root at the rear.
Step 9: Flight
For the Killer Owl with winglets, a swift throw is necessary for long range, high speed flights. It can also be made to do stunts, such as loops, low-level flight and vertical climbs and recovery.
"A73-2A (No Winglets):
For this version, a moderately fast throw is necessary. This plane will fly a long range at a steady, moderate pace. This version can fly very slowly, and almost hover.
