Reviews (103)
Includes 103 reviews aggregated from around the web.
Owners are positive. The Amazon listing shows 4.6 out of 5 from 103 ratings. Buyers praise strong torque and plenty of power, with one noting it works at 8.4V and does not break weaker steering parts in a bind. Owners use it in rock crawlers, a 6S Mojave and an Axial CJ, and say it keeps up with servos that cost nearly double and is quiet. Value for money gets some mixed comments, and a couple of buyers raised quality concerns.
