Reviews (2)
Includes 2 reviews aggregated from around the web.
There are few reviews for this servo on the web. Owners who recommend it call it exceptionally strong for the price, strong enough to steer a heavy rig with ease and more than sufficient for a large scale truck, and one says it does not buzz the way some other brands do. One owner, however, found a replacement unit noticeably slower than its rated speed and saw nearby steering twitch when it was driven, which was suspected to be interference and was not resolved.
