Reviews (8)
Includes 8 reviews aggregated from around the web.
There are few reviews for this servo on the web. Owners in car-racing forums say they are very happy with it, and one reports steering as fast as their Savox brushless servo. The retailer's product listing shows an average of 5 out of 5 stars, though the number of reviews is small and no written complaints surfaced. The servo has since been superseded by a newer ProTek model.
