should or keep it the same?

I hear your pain cosworth. For what it's worth imho, the appearance of these mini-hydraulic rams is first class looking at them nicely fitted and plumbed to the models and some of the fits here on RCT&C are works of engineering art imho. But operationally they appear one big problem after another. I've agonised over this same decision for 6 months as to going screws jacks or hydraulic and I'm right at that point now for my big dozer build. I'm going with 7 x frigelli screw jacks. Somehow I'm intending to cover the square appearance with some type of tubing to give the tubular appearance of a hydraulic ram. A few wires and an esc are much simpler than hydraulic hoses blowing off and spewing oil everywhere, pressure problems, oils, pumps, valves, power loss, speeds and the like. Hope that helps.
