Reviews (5)
Includes 5 reviews aggregated from around the web.
There are very few reviews for this servo on the web. A Tamiya builder installed it in a BBX build and recommends it, and another commenter says spending about $70 on a Savox over the cheap Amazon servos is night and day, with faster reaction, more control, and a servo that is less likely to break even without a servo saver. No failures were reported.
