Yea, that's what I had too. I never really had any problems with the servos or controller. Just don't trust green/yellow/red battery power light on the controller. As soon as the light goes from green to yellow change the batteries, unless you run a failsafe. I learned that the hardway after I lost signal and my buggy shot across a parking lot into a curb and into a ditch at about 40 mph. [:@]
