The "-1" variant is heavier and has a larger wing for long, smooth flights--making it a great cruiser. The "-2" variant, on the other hand, is lighter and has a smaller, tapered wing for speed and agility--making it an excellent choice for a small stunt plane. Due to their great commonality, a "-1" can be converted into a "-2" with a few cuts and the removal of one staple.
TAA USAF Designation: D146-1 (Straight wing with leading edge extensions)
D146-1G (A "-1" with landing gear)
D146-2 (Tapered wing)
Step 1: Materials
1 Piece of 8 by 10.5 inch graph paper (4 boxes per inch)
Step 2: Begin Construction
Solid lines indicate places to cut. Dotted lines indicate fold lines.
Note: 1 box = 0.25 inches
Step 3: Making The Rudder
Step 4: Making And Taping The Fuselage
Step 5: Applying The Wing And Stapling
Now it is time for you to work with your wings. Cut them out along their lines as shown. Then apply the fuselage to the bottom of the wing with tape. Cut off any excess.
For the "-1" variant, apply two staples to the aircraft in the area of the counterweight fold. For the "-2" variant, apply only one at the same place.
Step 6: Flight
Because of their great commonality, the two models of the Dragonfly need roughly equal launches. Give each a very light but quick throw, holding with your dominant hand's index finger and thumb and let go. If your Dragonfly has stability or heading issues, apply a slight dihedral deflection to the tailplane and/or wings. Enjoy!
