Making comparison between CG/IMU relative position from Mini 3 pro and mini 4 pro I discover a difference on CG position, that is normal if the two drone are completely different , but in case of mini 3 and mini 4 : -17 mm delta in z axis are...
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 /...
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...
