Reviews (16)
Includes 16 reviews aggregated from around the web.
There are few reviews for this servo on the web. Buggy racers report it feels awesome with plenty of torque, even without servo savers. One Arrma owner found it noisy at center and had trouble with the horn screw fit, since a screw was not included.
