This article presents a method of using LEDs on the wing tip of a flapping MAV (Micro Aerial Vehicle) for observing the wing tip trajectory. In general, the wing tip trajectory is recorded by a high speed CCD due to the higher flapping frequency. However, using high speed CCDs is not convenient because the equipment is heavy and not portable. In order to overcome this problem, this work installed LEDs on the wing tip of our flapping MAV. And then the images of the wing tip trajectory can be recorded by usual digital video camaras (DV). Finally, we confirmed that the trajectory is a figure-of-eight.
