HAHA! I remember that!

In my opinion the esc mfg should eliminate manual timing and let the esc manage it. if motors are regulated by ROAR for resistance and so on then eliminating the errors...

the best timing is timing that moves continuously with rpm. there is 1 timing point that generates maximum torque for every rpm. as the rpm goes up or down the timing must do the same if you want...

that is very cool and it appears to be correct. It get really complicated if you add a load to the motor. Good and bad timing is a function of RPM or rotor velocity. your results measure efficiency...

remove the mechanism from the servo. does the current go down?
program a center point different than the one you have now. does the current go down?

first-the servos must be the same. second the load on the servos must be the same (work). if all of this is the same then swap the servos mechanically and see if the speed moves with the servo. if it...

I know the axe is FOC but is it running skewed magnet stacks? Hobbywing tech is legit. I believe they would be first to the punch if they aren’t already.

the position, whether its by hall effect or back emf, is what triggers the esc to generate the field.

More poles does matter depending on your problem. cogging is less of a problem as rpm goes up....

its all about resistance. what does resistance do? it creates heat and current drop.

too much chronic heat and the plastic melts. look for loosening connectors.

heat and internal fractures to the magnetic material cause magnetic force loss. exposure to other magnetic fields can cause a force loss. its all kind of knit picky though.
