Owners rate this servo very highly: all 17 reviews on a helicopter retailer's listing are five stars. Buyers use it as a mini rudder servo on helicopters such as the RAW 500 and Spirit GT and call it precise, quick, sturdy and reliable, with one describing it as the gold standard for a mini rudder servo that runs cool. Several recommend buying the programming box to set the frequency and centering.
