The internals are impressive looking. Thanks for the pics. Wish I could buy it from you.

If there is, you just wind the kevlar string on with a power drill, and then brush some epoxy (or the correct stuff) on the kevlar string.

Thanks Luciano...

Looking at the rotor, it has 12 flats on it that can be felt thru the kevlar wrap. Does that mean it is a 6 pole motor? Or am I missing something: reasonong is that a magnet has 2 poles, and 12 divided by 2 would be 6?

If it is a 6 pole motor, should I run higher timing? Would that improve performance?

I always thought the Pletts were 4 pole, they even have P4 (poles 4?) in the part number. After running my big maxx on the MGM controller and looking at the peak rpm (when set for 4 pole), I get a max rpm of 78,000 on 6s (22.2 volts) in the software. If you convert that over for 6 pole, it would be 52,000 rpm. The big max is supposed to be 2300 kv, so 22.2 x 2300 = 51,060 rpm, which makes more sense and leads me to believe it IS actually a 6 pole motor.

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.

All Castle Creations speed controllers provide dynamic timing advance. This means the advance setting changes with speed and load on the motor to maximize the efficiency of the motor as all speeds. 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 really would like to have a Big Maxx, Expecially considering how well the Maxx w/fan runs in my emaxx! I bet that 5s with the big maxx would be a handfull!

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.

GO PLETTENBERG, all the rest is HYPE - 'TRUE HYPE" not by Patrick

Fact of a matter was that the 9920 and the 7XL preformed the same in my savage than the schulze/bigmaxx setup, so i jumped to that conclusion, considering the schulze setup was more than twice as expensive. my schulze burned, the bigmaxx his bearings where having play after a few runs. the 9920 didn't die on me, it was the entire setup i was impressed about. I guess i didn't know how to utilize the holy setup!

Maybe you can teach us how to utilize a 4 pole motor, and maybe this holy grale pays off.
