Hello, everyone. I am a new member and I'm very happy to join this platform. I'm going to use a DJI Mavic air 2 for my university project and can I get rpm, thrust and torque values in the Mavic's in-flight log?

There are members here that can get into the nitty gritty of the flight logs, unfortunately I'm not one of them.
There are options to retrieve the logs that will give you basic information about a flight but reading the x y z values of a flight is above my pay grade.
Follow the instructions from this site to retrieve a flight log and see what you think.
DJI Flight Log Viewer | Phantom Help
Upload and view flight logs from your DJI droneswww.phantomhelp.com
Another site would be AIRDATA.
Drone Data Management and Flight Analysis | Airdata UAV
Need an easier way to manage and analyze drone flights? Get notified of potential problems, keep up with drone maintenance, and create customized reports with Airdata UAV. Sign up today!airdata.com
Both are free to use but if you spend some money on the flight reader, you can get more details about the flight
Good luck and welcome to the Forum.

Those aren't in any of the logs generated by DJI drones... you need a test stand with a thrust & torque sensor to measure these....However, unfortunately, I couldn't find or see the thrust and torque values.
Thank you so much for reply slup ! Bad news. Maybe I can use mathematical equations to convert from rpm graphics to torque graphics. But I don't know of any method that can transition to thrust. I guess there's no other way.Those aren't in any of the logs generated by DJI drones... you need a test stand with a thrust & torque sensor to measure these.
Perhaps you could say a little more about your project?Hello, everyone. I am a new member and I'm very happy to join this platform. I'm going to use a DJI Mavic air 2 for my university project and can I get rpm, thrust and torque values in the Mavic's in-flight log?
In my project,I just want to measure thrust and torque values. Thank you for your reply Bud Walker. Yes I am talking about individual motor torque and thrust, not airframe.Perhaps you could say a little more about your project?
Are you talking about individual motor/prop thrust? I suspect that motor RPM is mostly linear with thrust. Might be difficult to determine units though.
Similarly, is it individual motor/prop torque or airframe torque?
Here you have a guy that measure this in the proper way & what equipment he uses...In my project,I just want to measure thrust and torque values. Thank you for your reply Bud Walker. Yes I am talking about individual motor torque and thrust, not airframe.
You could get close to measuring thrust as a function of motor RPMs. Attach a weight on a cord tied to the airframe. Try to get it close to the CG. When the AC is hovering the total thrust will be the attached weight + airframe weight. Thrust / RPM for a single motor will beIn my project,I just want to measure thrust and torque values.

Nice find.Here you have a guy that measure this in the proper way & what equipment he uses...
