I have been using the BUCK regulators. They have been a little flakey. What regulators have each of you used with success on the larger arms like the Lexi? I checked the Buck Regulators and they are rated at 2A. I was running the 12.6v-13v to ONE regulator and to the H-Bridge, then to the ServoPowerBoard, then to the Servo. i am also powering the two EZBs from the 7.2v Regulator. Now, am I understanding right? this ALL has to be done One Regulator for ONE servo? This is going to be a Mess.
