Quality checking a brushless motor after ESC issues
 
Hey everyone,
This past weekend I had an ESC burn up. I happened to have a spare (different brand) ESC on hand and I got it soldered up, but from a quick bench test, I felt like my motor wasn't pushing as hard as it did prior. While some of that could have been the other ESC, it should have been pretty comparable from a power standpoint to the previous one.

Is there a finite way to test a brushless motor to see if it was permanently affected by the previous ESC problems? I opened up the motor and it is still clean, no bearings out. No bad burned metal smell from a short. It seems perfectly fine (obviously appearances can be deceiving).

Thanks in advance!!

Did you re-calibrate the different ESC to the radio?

Yeah, the esc we put in was a Tekin RX8 Gen2, so the first thing you need to do is recalibrate. If you don't, the ESC wont respond to anything.

I also reset all of the throttle/break settings on my remote profile, as well as tried a completely new profile as a test.
