User Note

Check in: 9/27/2019, production code 1829.

Inspection: 9/30/2019

According to the team manager, there’s questions and concerns of this case.

  • We managed to inspect the ESC again.
  • There is no problem with the ESC. The only possible cause that I can see was the worn out 5mm bullet connector on this ESC. Please see below photos.

  • The bullet connector on the ESC aged and became extremely loose when plugged to our testing battery. The photo can show the connector cutouts were very pressed, as well as the gold plated surface was decolored.
  • We tested carefully with and confirmed there’s no problem with the ESC itself. Please see RMA1250 second test video.  
  • We are only able to test the ESC to confirm itself. It is OK. We won’t suggest you to spend money to fix on something that works fine. The things that might be worth to try were to replace the bullet connectors, clean up the ESC to avoid residues to cause internal statics or shorts to damage the ESC. However, there were trade-in and rebuild options for ESCs if you decide to go that direction. Please contact your team manager if you have more questions.

Side note: an ESC is a electronic device. It is normally GO or NO GO. If it does have a problem, I would not be able to power on and keep running it for 2 minutes without seeing a spark on my testing bench. The ESC itself is just fine. That was something else out of the ESC that caused the sparks. Unfortunately, I am only able to check this ESC for you to make sure it’s fine. Hopefully that provides a logical info for you.
