Very fast. Works good on 6V but, 8.4V really wakes up this servo (both in speed and torque). I use it in 1:8 buggy and everyone is surprised that it's faster than >200USD brand name servos! I gave it 4 stars because it's not totally quiet (like some other Goteck servos I use), and case screws backed out because they weren't locktited correctly and servo stopped responding because of it (on a helly that would result in a crash).

I have these im my Logo 600 all around running them on 2S LiPo.
They drain 300mA in 5 minutes of sport/ mild 3D flight and does what it say on the box.
They have 43 flights and 1 crash on them so far and im exited to se how they preform in the long run.
