I had a similar issue with a mm. LOTS of cogging, no throttle etc. Turned out to be a loose motor wire solder connection. Fixed it, and mm runs like it did before.
Had it together for 2 min, then it went bad... was checking things out with the batt. conected and the switch off.. then the smoke started. I am very capable... just not happy not sure what happend...
all the settings were tripple checked before even turning the esc on... i'm a a loss for words....
