Includes 5 reviews aggregated from around the web.
There are few reviews for this servo on the web. An RC Tech forum member says SRT servos look and feel great, are super quiet and have no slop, while another says this model and the BH9027 are too fast for off-road buggy and strip gears, though he strips gears on every brand.
