I've recently purchased and used a Tower Pro 60A esc and the instructions are poorly written and lacking. I have a choice of 2, 7, 15, or 30 degrees to set the timing,and 8, 16, or 32KHZ to set for the pwm. Recently in an ad I read that an outrunner, which is what I have, should have the timing set at 25 degrees, I have no idea what pwm even stands for... maybe pulse width?
