Motor Timing tutorial for Actro 32-3
I've moved my Ion pieces parts around between the two I own. Addicted to tinkering I am. Anyway, I noticed on the Actro 32-3 (95T main gear) bird, that below about 1650 rpm (head speed)or so, it vibrates quite a bit. I'm guessing pole slippage bewteen the rotor and stator field. Then at higher speeds, vibes go away and it sings sweet and pretty! (must be working as a synchronous motor at this point). Obviously motor characteristics are different between the Actro outrunner and the stock Hacker on my other Ion. Both are running on stock Hacker 77-o-H's with identical settings, per suggestions of MinAir Reps (0 deg timing, 8khz switching). I've violated the conventional wisdom on the Hacker/Hacker combo by using THR curves below 80% (actually more like 65-70%) and it's been working great!! 1650rpm and esc about 115F after 10 minute flight.

So what I want to know is how motor timing affects motor performance, and ESC performance at a variety of head speeds, and any thumbrules or guidelines you veterans know from real world experience.

Any thoughts would be greatly appreciated, Don.

Conventional wisdom says to up the timing on high pole outrunner style motors. You can do this and a little more performance at the expense of a little more motor heating (less efficient) will be had. Frank Koehler, the guy who builds the 32-3, has said to not run the timing of the 77-O-heli control advanced at all with that motor, leave it at 0. I'm clueless as to what advancing the timing at low throttle percentages would do...

As for running the 77-O control at lower throttle percentages, you can, for hovering and gentle flying around. I would not recommend pulling hard on the heli with percentages set low as the control will begin to heat and the chance of a thermal-off becomes very real.
