MM/Neu...just make somes test -
10.30.2007, 11:44 PM
OK, first, my revo is almost done, the only thing missing is my MGM16018. But tonight, i've my MM sit on my table on my workshop, and i decided to give it a try with my Neu 1515, 1Y.
I'am geared 16/38 and you know what???
NO COGGING AT ALL  It start verrrrry smooth from a dead stop, and accelerate like a beast!!!!
This FlightPower EVO25 have moooooooooore power than my old 6000mAh, 14.8 maxamps pck.
I'am very happy with this pre-test and i don't know why i've spend $300.00 on my MGM 
Anyways, i'll put the MGM in the truck as soon as i'll recieve it, and i'll keep the MM like a spare, because i think that MGM is very long for services

That's good to hear! Is it a new MM or an older one?

Doesn't surprise me. We have a bunch (and I mean a bunch) of guys around here (including myself) that run a Neu/MM combo without cogging. We re-wire the controller with 12ga and direct-solder. Add some good batts and the right MM settings, and you're good to go. The Neu/MM "problem" is way overblown.

I think its because, you are using the Y wind. I seen those with the D winds have a lot of trouble. gearing helps as well
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise

Don't know the difference between the "Y" and "Delta" winding and cogging effect.

The Y and Delta winds use the same number of wires, as it were, but are configured differently to produce a higher or lower Kv rating. How this effects cogging exactly I dont understand either- maybe its like more agressive timing vs softer timing, but in the actual motor and not via esc programming?.... whatever, the only reason no to use the MM esc is simply down to voltage and current draw limitations, but it all depends on how hot & hard you drive I guess.

Ya, my driving style is very "soft". Never nail the trigger from dead stop.
I'am a track racer, and like to put lot of expo on the Tx to keep the thing controlable

Happywing - what is you set up that you are using? Any tips to keeping the cogging to a minimum?

MM/Neu 1512 2d/f 2600kv geared 11/46
Brake 30%
Punch Control 40%
Start Power Med
Drag Brake Disabled
Motor Timing Normal
We have found that pinion size has a lot to do with cogging. I have a high Kv motor in order to run a small pinion. Mine had a slight stutter in my first buggy. My present buggy is almost a pound lighter and the stutter has disappeared. If you can reduce weight and rotating mass, it helps.

I ran into that problem with the NEU in mynE-Maxx. The larger diameter motor hits the tranny and precludes smaller pinions. IIRC a 17t pinion was the smallest I could get to mesh.

The 1512 2.5D on MM in my buggy works well also. There is occasional cogging, but I don't race (and if I were to, the buggy wouldn't be stopped much at all).
