Reg , I just bought the valves from them for this awhile back . The pump is a Micropump I got off ebay ( thread in the construction teck forum ) I modified it for the $* log truck but it was just to bulky to look right with the limited room I have on that truck . So it went here . I have to make cylinders and a PRV and need an esc for the pump and finish the blade then it'll be full operational . The quickest and relaxing build yet for me that didn't cost a bunch like my big Mack
