Finally got around to installing my new HobbyWing ESC's to replace the TBLE02-S on both my Sabre Mini's.
Only now, I got a bad bearing somewhere on my 4WD Mini. I can hear the worn bearing ..
I'm guessing it's the spur bearing... what do you guys think? I will be replacing that first tomorrow to see if the noise goes away... if not, process of elimination.
