Description
Use this handy portable tool to keep your servos centered while you mount them under the layout. The tool consists of a battery box connected to a small circuit board that continuously puts out a centering signal for the servo (1.5 ms pulse). Keeping your servos properly centered while mounting is the key to making the servos work best. The battery box has an on/off switch to save your batteries when not in use. Everyone using servos for turnouts needs one of these.
Requires 3 AA batteries.
