Many years ago, I used to fly rigid stunt kites. Diamond in shape with two control lines. But being rigid they would be prone to braking if flown into the ground, which is something I did a few times. With an aerofoil kite there are no components other than the material itself, so pretty indestructible. Also, the aero foil kite is a lot more efficient which means even with a gentle wind the kite will fly. However, if there’s a strong wind then there’s some fun to be had! Kite surfing in my wheelchair for example!
