Reviews (27)
Includes 27 reviews aggregated from around the web.
Owners rate this servo very highly: all 23 reviews on the maker's page are five stars. Buyers praise its fast response and strong torque, say it holds up even at 6V, and one owner runs eight of them. A crawler owner reports running it hard in several rigs, breaking a knuckle and an axle housing while the servo kept working, and another has had one going strong for two years. It is considered a little overpriced, and many reviewers also praise the maker's customer service and handwritten thank-you notes.
