I have these coreless motors and propellers. I created two kinds of home made drone frames. I am not currently using any receiver. I arranged the motors so that diagonally opposite ones turn in same direction. Adjacent ones turn in opposite directions. I arranged the propellers so that wind blows downwards. When the frame was heavy the drone barely lifted. It would slowly slide on the ground. When the frame is lightweight it rises and topples very fast.
Am I right in thinking that uncontrolled speed is full speed and so it topples when frame is lightweight.
To make it rise gently without a receiver is it only a matter of making the drone frame suitably heavy?
