That's what I'm assuming as well. I didn't amp test to see what I'm drawing but I can tell it's not close to it's rating. I've got one setup on my workbench right now. I'll keep hacking on the esc program till I figure out what the issue is. My typical "start the receiver with full throttle" definitely doesn't initiate calibration... I acts like full throttle at boot puts it into program mode. Just not sure where I'm at from there. I'll do some testing and take some notes. Hopefully I can wrap it around my head without any instructions lol.
