Well it sorta worked. I have a heatsink fan on the motor and added the cap and pulled the fan wire. 80% improved but not gone. Im running latest hw firmware but noticed sp had a "patch" for fasf rx. I tried to downrev and test that firmware but the sw would not allow it. I surfed the threads and there is a lot of confusion on this topic.

Any chance this is esc firmware related.

Thx
Joe
