I would like a "child safe" drone like this one for a short theatre scene, unfortunately this drone is too small, you can hardly see it. What is the biggest drone you can get with a touch-safe cage? I think the autonomous take-off function of this drone here is great, you can (symbolically) blow on it and throw it into the air, then it takes off.... But it wobbles around a lot, far too much, unfortunately it doesn't stay within a small radius and, in the worst case scenario fly into the audience. I will therefore tie it down with a thin thread so that the drone wobbles around with a little "pull" on the thread. Does anyone know where I can get such a small drone with a protected rotor cage, it should be about 20cm in diameter.
