If it is a 6 pole motor, should I run higher timing? Would that improve performance?
That rotor looks just like the one in my Extreme. They might use 2 magnets per pole. Funny thing you asked about timing. The 6S controller that I've been testing was acting up when I had low timing running the Aveox. When I went to mid timing the controller worked perfect. Now days I'm getting more and more confusing as some companies say to run low timing to keep temps down. I always go mid or 5 degrees of timing for 4 pole motors and high or 10+ degrees for 6 pole motors. My 60A controller burned when I changed timing on it when I was running the Mega ACn16/15/1. I had 15 degrees of timing and it was doing awesome, but I made a mistake and changed the timing instead of another setting and a couple of FETs went dead.

Very interesting, because that's what I've always heard too:

Changing the timing advance setting lowers or raises the range in which timing advance moves. The advance settings actually overlap quite a bit.

Generally, outrunner motors work best with high timing advance. However, one of the motor characteristics CC ESCS compensate for is motor inductance. The high inductance of outrunners pulls timing advance up. This means that for most medium to small outrunners 'Standard' timing advance works well. With these the only reason to lower timing is if the motor is running too hot or if it starts making noise above half throttle. The noise means the ESC is loosing sync with the motor.

With larger outrunners we recommend 'Low' timing advance. The larger the outrunner the higher its inductance. These larger motors inductance pulls our ‘Low’ timing advance up to the higher timing advance these motors want without having the advance get so high that the ESC can no longer sync the motor.

Hope this helps.

However, if you have a large 2800 series motor that makes noise over half throttle lower the advance. It is also a good idea, if you like to fiddle with things, is to change timing between 'Low' and 'Standard' and see if full throttle produces more or less RPM.

To make it easy, as long as the motor is behaving OK don't change timing. If it is making noise at higher throttle settings or running too hot lower timing.

I realize this is about outrunners, and we've been discussing inrunners, but I'd like your thoughts/experience too.

I've only goofed with timing on a outrunner I've got. I never tried higher timing with it, because it got pretty darn warm just on normal, and changing to low (or lowest) didn't help at all. The motor I was trying was a Axial 600XL, now I'm wondering if higher timing might be worth a shot?

It is great motor and I still have bad fellings towards Serum he compared this motor with 7XL!!!!!!!

This is the best motor you can get from Germany, even Lehner is nothing to compare.
At the time Sculze was the only one ESC which can handle this motor, but now MGM can do great and I hope MMM and MM with 1.17 software.

You cannot bring feigao to the level of Plett, even if you gold plated it!!!!

Balancing is very important and plett is the best in that area. I had plett's , lehner, feigao 1-4, nemesis, mega, medusa, kontronic, align, axi, aveox ... and none of them can even get close to plett.

It is not advertisement, it is pure facts, if you have budget than plettenberg is the motor for you.

BUT YOU NEED TO KNOW HOW TO UTILIZE 4-6 POLE MOTOR it is not the same as 2-pole and BrinG calculator doesn't work great here either, not that Brian is wrong, it is very unique motor case.

Good info Artur. I have had alot of success running my plett motors with quark escs. I will try your mod1 MM with the maxx w/fan on 4s. It is doing fine with the quark 125b, but I prefer the programability of the MM and the lvc settings.

What would you suggest I set the timing at on the MM for the plett? I am guessing that higher timing will be better. Patrick mentioned that the MM auto figures the timing, and the adjustment is in that range, not from a baseline setting. If that is the case, normal timing should work for the plett? Or should I go higher?
