Reviews (7)
Includes 7 reviews aggregated from around the web.
There are few reviews for this servo on the web. Video reviewers say it is far more powerful and sturdy than the stock servo in an Arrma Grom and an SCX24, with one saying the truck no longer shakes under load. It is pricey, but described as one of the best steering servos you can buy for the SCX24.
