KO Propo has just released the PDS-2531, a digital mid-profile servo. Standard features include metal gears, 0.13s transit speed and 9.5kg-cm of torque. The coolest feature, however, is the clear case bottom and integrated LED! When the power is on, the servo gives off a blue, red, or yellow hue, adding a little pizzazz to your chassis!
