That's what I am hoping. When I asked about the ability to clear the programming setup back to the default settings, they said that it was impossible. I can't imagine them putting burned chips in at assembly...
does it have auto timing? are you using a stick radio? If it works for 4 levels of programming then the problems is not a result of a burnt chip . It sounds like a firmware or a tx issue makes sure you read the manual closely. Not that you didn't but the writing is small on most esc paperwork you might have missed something relevant to your style radio. Keep me posted.
Will the instructions you posted work for ALL of the 50amp controllers you've sold up to this point? I bought a couple when you first started selling and wanted to make sure I can use these instructions.
