5s li-po w/mm esc
 

Anyone using a 5s w/the mm esc w/ success?

Is it capable of handling a 5s 4000mah?

yes. I run 5s on the MM. The newer MMs will not handle the 5s. They simply give an overvolt error. The older ones will run 5s if you are carful with the gearing.

i also run 5s with a slower (12xl) motor.
