I bought some new simonk 30A esc. However, they slightly differ from the ones you get with the course.
Here is the ones I got:
This differs from the one provided by this course which has the label “NIMH:5-12S LIPO:2-4S” on the esc instead.
The one provided by the course works (motors give a beep when powered on), while the ones I got do not work (no sound). Can someone explain why since they seem to look that they should be identical? Also where can I go to buy the ones provided by the course, I am having difficulty finding them online (while the ones I bought are the first thing to come up when looking for “simonk 30A”)?
