Default Any Monster Max cogging issues?

I am considering upgrading from the standard Mamba ESC to the Monster Max ESC for my converted Kyosho ST-R

Are there any cogging issues with the MMM as there were with the standard Mamba? Any other issues with the MMM that I should know before shelling out the dough?
Thanks.

Cogging is problem that still exist with some slotted motor for 1/10 scale. Mamba controllers with the last software 1.17 or 1.20 for MMM are much smoother than they used to be.
If you plan to use it for 1/8 scale, don't worry MMM run slotted motors like NEU/Medusa and even most el cheapo chinese motors without problems

Only cogging I've seen mentioned is when rolling backwards (like down a hil that you didn't quite make it up over) and trying to go forward again. Othe than that, haven't read any complaints about cogging with the Monster.

If you'll update the firmware in your MM to the latest, that new software is supposed to all but eliminate cogging.

with the mamba monster ESC and my neu 1512 2.5d or the Medusa 2000kv motor I had, you would see cogging on the latest software only with punch control set at zero % and deliberate miniscule throttle pull, or, a hard full throttle pull with the Neu on lowest timing, no punch control. as soon as i added in 10% or more, it went away.

I would say for this happening in racing, it has never been an issue with the mamba monster and the 1.17 software.

I just noticed that they have a built in switching BEC. Is anyone using an external BEC still, or the one built in?
