Seems to me I read somewhere that DJI started out in a University supported business incubation program that really took off big time and the amount of high tech engineering and automation resources available at some universities can be quite extensive. As far as PID loop control .... that's...

For each camera axis, i.e., two or three, there are several adjustments required including a torque or deadband parameter and the typical PID loop control. And PID loop control is the most common and practical application of calculus..... so that is a clue as to the potential struggle and...

I get the impression that an automotive or industrial runout gauge would he the way to go and a smaller hobby scale runout gauge is not available. But if so.... can someone please suggest what and where to look?

I was under the impression that the motor pole count is always equal to the motor coil count... but these motors are sold as 22 pole yet have 24 coils...... Can someone please explain this...

Obst... Excellent work. I will stick with 2axis BG to keep weight down and work with MR yaw for panning for the short term. If all goes as expected, when I really need panning BG axis the weight and size of the HD camera will come down. I can easily custom Mold a shroud using CF and my vacuum...

You may also notice in eCalc that you can adjust the prop thickness ratio @ bottom right. A 1.1 gives more airtime than the conventional clark airfoil at 1.3 or higher. Check out the super thin cf paddle props.

Seems that DJI is focusing on a common RC receiver c/w s.bus and more channels for more than one MR product and also a 100% compatible RC xmitter. Just wondering though..... what the heck is DESST?
