Introduction: How to Make the Super StratoCardinal Paper Airplane
Fast, long range and aerodynamic, the Super StratoCardinal is a small "drone-cruiser" paper airplane meant to complement the very similar but more elaborate StratoCruiser.
The Super StratoCardinal is a spiritual successor to its namesake, as the wing used is actually identical to that of the StratoCruiser, rather than the StratoCardinal. To accommodate this larger wing, the fuselage design of the StratoCardinal was altered slightly and extended. Design of the prototype for the aircraft was a short time and flight testing was quite routine. The aircraft was approved for publication shortly thereafter, and is now ready to be flown by origami aviators all over.
TAA USAF Designation: D333-1
Step 1: Materials
1 Piece of 8 by 10.5 inch graph paper (4 boxes per inch)
Step 2: Begin Construction
Fold your paper in half so that half a box is at the crease line. Make a mark, then measure 6 boxes back and make another mark. From this second mark, measure half a box up, three boxes behind. From this third mark, measure and mark 3 boxes upwards over 1 box backwards. One box in front of and below the last mark; then make a line stretching two boxes forward from this fifth mark. Beyond this, the pictures explain the other marks needed with less confusion--better than I can explain with words. Once all is marked out, cut out the fuselage.
Take another sheet of paper that is folded in half along the lines of boxes. Mark out the wing as shown (1 box of constant chord at the root; a leading edge sweep of 1 box of chord decaying every 4 boxes outward from the constant chord box; and a trailing edge sweep of 1 box of decay along the 5 boxes of wingspan). This will complete the wings. To make the horizontal stabilizers, measure 2 boxes along the crease, measure two boxes upwards from one mark and make another point. Then draw a diagonal line connecting this new mark to the one further away. From the mark you just made, measure one box further away from the one now connected to the line and make a mark. Sketch a line between this mark and the other mark along the crease. Then cut the horizontal stabilizers out.
Solid lines indicate places to cut. Dotted lines indicate fold lines.
Note: 1 box = 0.25 inches
Step 3: Making the Fuselage
Begin constructing your fuselage by folding the counterweights into the fuselage. Once they have been folded, unfold the fuselage and cut off the right vertical stabilizer. Once this is done, restore the fold. After doing this, fold the vertical stabilizer forward along the dotted line that indicates the center of what will be the slot for the horizontal stabilizers, then cut. After this cut has been made, cut away the bottom of the fuselage beneath the diagonal line near the rear of the fuselage. Following this cut, cut along the vertical line of the ventral fins. Apply tape where designated and fold the ventral fins as shown.
Step 4: Applying the Wings and Horizontal Stabilizers; Stapling
Cut out your Super StratoCardinal's wings and lay them beneath the fuselage. Apply tape where designated to secure them to the fuselage. After securing the wings, cut out the horizontal stabilizers. Thread them through their slit and then secure them with tape as designated. Apply one staple to the counterweight area of the Super StratoCardinal to complete it.
Step 5: Flight
The Super StratoCardinal is a moderately fast paper airplane and as a result, its launch profile sits between that of other drone cruisers and fighters. Launches should be at neutral or positive attitudes at medium to high speed. Elevator trim and the ventral fins may need adjustment, so test flights are highly recommended. Additional applicable surfaces include slats, flaps, flaperons, elevators, ailerons, spoilers, spoilerons and a trimmable rudder. Enjoy!
