Regardless where it's made we've tested servos from Taiwan that were advertised as 47kg at 7.4v, and only tested at 28kg. Most servos sold online like Amazon, etc..that are 25kg coming from either market is rarely going to test at 35kg or 45kg that they advertise. We tested 1 brand of servos 25kg, 35kg, and 45kg, and the 35kg, and 45kg tested the same as the 25kg at 7.4v. You will find good ones in Taiwan, and China, but also really bad ones. It's just really going to come down to the integrity of the factory producing servos, as well as the 3rd parties purchasing from them. Just cause someone notices a difference between one servo from another, and the difference is positive does not mean what they actually purchased is performing as advertised. It's good to have an opinion that your experience with whatever brand you purchased is positive, but in the end it's like a car doing a butt dyno test, it's just an opinion..without a dyno it's just a feeling.
