I could not find a better category for this thread, hope it's OK.
I’m a student at NTNU in Ålesund and I’m working on my bachelor thesis. In my thesis, I’m using an octocopter, and I’m currently working on the theory part of the report.
I haven’t managed to figure out exactly how a multicopter rotate around its yaw axis. Because there seem to be a lot of confusion going around the internet on how a multicopter turns around the yaw axis. YouTube videos, web pages and even books don’t seem to agree on which engines must spin faster in order to make a multicopter turn. Some sources seem to think that for a multicopter to turn CW the CW engines must spin faster than the CCW engines. And equally as many sources claim that the CCW engines must spin faster to turn CW.
Take these two YouTube videos for example:
This one claim to increase RPM on CCW in order to make the copter spin CCW: https://www.youtube.com/watch?v=Z_T6LBwuBKY&list=PL6XNeEfHbOUgz5ovm6yuUOxKPcEhw84XE&index=8
And this video claim the CW engines need to spin faster in order to turn CCW due to torque: https://www.youtube.com/watch?v=DNc8o9CZLHU&list=PL6XNeEfHbOUgz5ovm6yuUOxKPcEhw84XE&index=1
Can anyone help me clarify this subject? And do anyone know about any good sources I can use as a reference in my report regarding this problem?
