RE: Dymond D47 servos
Website claims are all correct... except for the speed. Spec sheet that came with mine said 0.18 seconds. Rounded off CORRECTLY, that's really 0.2 seconds.
However, that being said, I really like mine. They are very powerful and super small. Yet are durable too. I've torn up other brand servos by accidentally banging the tail into the door frame, etc. I've bumped these several times, but they are holding up with no problems!
