question about RC4WD hydro pump

[cbazq271]

Hi, I have a question for anyone that has the excavator from RC4WD, or anyone that knows the answer. I want to know how is the pump driven? Is it bolted directly to the brushless motor, or is it geared down with metal gears. I can tell by the pics on the website that its not belt driven like my Vario. I want to know because I might buy the pump to use in my dump truck. Thanks, Chad
