I began designing the StarDragon in November 2012, shortly after the StratoBolt. I noticed that the StratoDragon was quite popular, but obsolescent and overly large. I set to work to address this by designing a new sailplane with greater capabilities. To accomplish this higher performance and retain commonality with comparable airplanes, I recycled much of the airframe design of the StratoBolt and then designed the new aircraft's wing. The prototype flew well, and an instructable slot was earmarked for it.
The StarDragon is quite capable, and can be used by educators easily.
Some usages for educators could include studies of:
- Glide ratio
- Hangtime versus other aircraft
- Weight and balance
Step 1: Materials
1 Piece of 8 by 10.5 inch graph paper (4 boxes per inch)
Step 2: Begin Construction
After the fuselage is made, take another sheet of paper that is folded in half along the lines of boxes. Mark out the wing as shown (3 boxes of chord at the root, by 5 boxes in width, with a leading edge sweep of 3 boxes of chord eliminated every 5 boxes away from the fuselage root and a trailing edge sweep of 1 box of chord every 5 boxes from the root). Then cut the wing out. 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
Step 4: Applying the Wings and Horizontal Stabilizers; Stapling
Once you have finished with the wings, cut out your horizontal stabilizers and slide them through the slit in the fuselage you made earlier. When through, fold them up and apply tape to the underside; then fold down.
Then apply one staple in the area of the counterweight. This will have completed your aircraft.
