Right on...:mdr:

I have been running my MM/BigMaxximum setup a little over 8 months now with no issues. I think from what I am reading your issue may be with the connecters. Try cutting the connectors completely out of the loop by hard wiring the ESC to the motor and see if the cogging issue persists.

My 2 Cents...

Cool.. I did not know this was possible.... that's sweet....

Thanks guys
 

I'm going to try hardwiring first. If that still isn't it, I'll try the Quark. I was really hoping to run the MM since I have an extra one. Any input from other MM users on the best settings?

how many cells are you running with that setup skillx?

4 now because I have a newer MM. But when I had an older MM i ran 5 all the time with no issues.

It is the motor!
 

I finally got back to this project. Using the Plettenberg, I swapped in my Quark 80b and the same cogging and extreme heating up occurs. I'm now convinced that there's something like a short in the motor. I have no continuity to the case on any wire but the heat build up is so fast that it could really only be a short.

BTW, with my feigao 8xl in the same set up with the MM, there is a little bit of cogging on start. Not much, but enough so you can't just grab WOT. With the Quark 80b, the cogging completely stops. Much smoother.

Is there anyone in N America who can fix this motor?

I know that ICARE-RC sells them, but as for repair.... unknown. Another possible cause could be that a mounting screw was screwed in too far, and damaged the windings. This is known to cause poor performance and rapid heating of the esc and/or motor. Me thinks the previous owner got a bit careless, then sold the system on to some unsupecting person; you. If the windings are damaged though, the cost of repair would be more than the motor cost you to begin with, since its not a simple task to to remove & replace them.... :no:

I have removed the windings from some big motors I have and it was fairly simple. All I did was heat the motor's can and the stator assembly came right off. Contact Plettenberg and see what they say.
