They are meddium quality. They are 507s(low end) with a bearing replacing
the Delrin bushing. Probably better that Tower or other <$20US servos. The
high quality $tuff are the 4xxx series with2 ball bearings. For a camera
pan/tilt unit we use Futaba 9202s which are high end dual ball bearing,
mainly because thaey are easier to modify.
