Servo's... What servos are you guys using in your trucks? The factory servo in the Cutback is S-L-O-W as heck (0.24 s/60 degrees @ 4.8V - 0.21 s/60 degrees @ 6.0V). I'm guessing that our factory speed control is set to 4.8V output right out of the box and from what I can tell from the Speed controllers manual there is no adjustment.
