NewBuilderFlyer Posted December 27, 2017 Share Posted December 27, 2017 See if you can spot the issue with this YEP 30A ESC. It has nothing to do with the lack of shrink wrap, nor the shortened wires (I cut them off to recycle the parts after i found the ESC was dead) Hint: it doesn't work because someone wasn't paying attention at the factory. And I didn't notice until it was too late! Quote Link to comment Share on other sites More sharing options...
Chris Jones 7 Posted December 27, 2017 Share Posted December 27, 2017 Wrong polarity on the wires. Quote Link to comment Share on other sites More sharing options...
NewBuilderFlyer Posted December 27, 2017 Author Share Posted December 27, 2017 Shame I didn't spot this before wiring it up. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted December 27, 2017 Share Posted December 27, 2017 Oh dear. I think you still have a case for a refund as you haven't touched the soldered joints. Quote Link to comment Share on other sites More sharing options...
NewBuilderFlyer Posted December 27, 2017 Author Share Posted December 27, 2017 And the replacement YEP ESC has a strange 'dead-spot' at about 50% thottle when I connect it to my motor. With another ESC the dead spot vanishes. No amount of programming the YEP will get rid of it. Quote Link to comment Share on other sites More sharing options...
NewBuilderFlyer Posted December 27, 2017 Author Share Posted December 27, 2017 It's from a well known supplier of inexpensive bits - so the chances of a refund are slim.... Quote Link to comment Share on other sites More sharing options...
NewBuilderFlyer Posted December 27, 2017 Author Share Posted December 27, 2017 Just submitted a claim but using Safari browser the various drop-down selections that are mandatory are not visible! Have to use Chrome instead. Another example of incomplete testing on behalf of HK? Quote Link to comment Share on other sites More sharing options...
NewBuilderFlyer Posted December 28, 2017 Author Share Posted December 28, 2017 And to be totally fair, once I had submitted the claim , HK refunded my money pretty much instantly. So a happy ending. Quote Link to comment Share on other sites More sharing options...
