At first i thought it was hydraulic also. But i kept on searching and found more of them on foreign rc forums. They are definitely not hydraulic which is really cool. On the forum where the guy made it, had a build thread, he didnt say how he did it. I see now that there are more so he must have been selling them. But i am really interested in knowing how he gets the speed and strength without hydraulics.
Oh and also, listen to it. No hydraulic pump. But you can hear what sounds like a screw drive or something similar
