I was thinking of making a video of me running the motors without the props attached. And then pushing 100% throttle for each of the 4 directions for each side of the stick. For eg. Right stick-Up Right stick-Right Right stick-Down Right stick-Left. And repeat for the left stick. My aim is to record the unique sound each direction generates. I crashed my drone on my 2nd day and always wondered if my motors are damaged. If it's a good idea to make this video so that all of us can compare, be it we crashed or never crashed before, and be sure we have the same uniform result, I'll make the video and post it here. Let me know if you all think it's a good idea.
