Viper ... I have got that problem before. Its not about perfection. Sometimes cheaper ESCs cause this. One will start quite a bit later, not about 1-2 clicks only. The power and RPM is also not the same. We had this problem with some El Cheapo China ESCs and I was going nuts trying to figure it out for my pal. Later, we changed to branded ESCs and it was a matter of 1 click only. Power was pretty equal.
