Before any flight, the weather situation should be checked. The flight on the intro page was conducted with no wind (not a breath of air moved the tree leaves). These conditions occur during
temperature inversions. Alternatively, the glider can be flown in a large indoor space such as a gym. But even indoors, care must be taken to eliminate or avoid drafts produced by open doors or windows, heating, air conditioning and ventilation systems. A good way to create a temperature inversion indoors is to run the air conditioning (or heating) for a while and when the system is turned off the air should be pretty stable. As when flying full size airplanes, the smoother the air the easier it will be to pilot the airplane.
