I doesn't seem to be any of those! Body length is 53mm, phase resistance is 1.4R and phase inductance is 1.9mH.

I found that when I set the current limit switch to 100% it ran worse.

I could increase the voltage to the board. The motors nor board run hot. Is it safe to do so, and should I make that mod listed earlier - http://www.mycncuk.com/forums/showth...ll=1#post19305
