RE: Any good reports on these
I am looking at r/c REPORT and on the back cover is a HitecRCD Advert.
It says the HS-5975HB, HS-5475HB, HS-475HB, HS-325HB, and the HS-322HD are all Karbonite geared.
October 2003 edition.
Hope this helps you guys. Have had Hitec servos strip on me, Futaba seize up, JR go wonky (drive from one end to other full travel). I think it sometimes is just the servo.
Good Luck out there,
