Reviews (5)
Includes 5 reviews aggregated from around the web.
There are few reviews for this servo on the web. Three buyers rated it five stars, saying it survives abuse without dying and is smooth, super reliable and the best bang for the buck, one running it in all of their 1/10 2WD cars. A truggy racer on a forum reports the same servos bought in 2019 are still going strong with no issues and the spares never needed.
