I know HOW to calibrate the ESC when it's got a properly working button. The problem is that it doesn't execute when I short the thing out. I works just fine when I do the basic same thing for changing program settings.
But this is just a dead end anyway, I'm sure. Again, the steering works just fine in channel 2, when I control the servo with the trigger.
Weird problem. Logically, it doesn't make sense to me.
