Harness the incredible power of your iPad or MacOS desktop computer. Design impressive handheld gliders that you can easily put together. Create whole squadrons of your very own designs that you can make soar! Have a contest to see who can design and build the best glider. All you need is our software, along with your iPad, scissors, a metric ruler, card stock and/or balsa wood, a little clay, and a bottle of super glue (for card stock gliders) or a hot glue gun (for balsa wood gliders). This software is a true designing application that includes authentic glider analyses and predictions. It requires a bit more effort to design and build your own gliders to fly instead of just watching simulations, or using prebuilt designs, but the payoff can be well worth it. By building your own gliders you will quickly learn much more about flight, while likely feeling far more empowered and satisfied seeing your designs glide off into the distance. The software is already a great success at many schools (students 11 years old and up).
