The ds3218pro is another story. The normal 20kg and 25kg are not good imowell the DS3235s are neither as fast nor as strong as they claim to be.... I've had the 3235 and the 3235 pro and got rid of them both.
servo specs aren't inflated as much as battery c rating but it's not far behind. The real reason I don't care for the cheap servos is that they don't center and that's annoying. DS3235 able to pull about [email protected]
and if you think that there's a problem with the methodology the a700 pulled an incredible 70kg on 8.4 volts and 67 kg on 7.4 v (which is what I'm running in my Hobao)
