Yep, I`ve used volt watches on three of my airplanes and the lights will dance some when you move the sticks for the reasons mentioned. My personal rule is to recharge ( or quit flying that particular plane for the day ) if I start getting a dip into the red light. I try to err to the side of caution by being conservative when it comes to batteries. Lost a 4* 40 to a bad battery. It wasn`t pretty!
