Meet the DJI HiTop, a conceptual drone that follows a tricopter format instead of the traditional quadcopter one. In simple words, it uses three rotors to achieve flight as opposed to the traditional four. Designed as more of a consumer-grade aerial toy instead of a highly professional one, the HiTop is a simple drone that’s built to do its job well. The body of the drone is much larger than you’d expect, but this turns out to be a feature, housing a bigger battery and more safety features to keep the drone up in the air for longer. From the top view, the drone assumes the shape of a 6-sided star, with three rotors and three ‘bumpers’ between them, adding as physical barriers to prevent too much damage to the drone or the high-end camera system underneath.
