Today we performed our first plane launching. Here is how our set up looked like:
Basically all you need is a slanted platform, a bungee cord, two hooks and a bunch of nails to put down the platform and cord into the ground.
The longer and the thicker the bungee cord the more energy there is in the tension, which would let the plane fly farther.
The propellers were not connected as we just wanted to test the launching by itself. Our first flight test failed as the bungee cord did not have enough energy. For our second flight test, we placed it 2 meters farther and voila.
