as far as i can tell, most all these no name servos are just relabled branded servos like the cs-80 and the ts-80s are rebadged Hitec 805BBs.
According to Futaba,
90 oz-in @ 6V = 6.5 kg-cm @ 6V.
So if my math is right it = 275 oz-in.
My question is, why would you trust a 1000.00 rig with a generic who knows what it is servo?
