Ah yes, that makes sense. Hydraulic will be beneficial there.
Are you going for a rotary feedthrough for the blade tilt and shift?
I use a spindle drive - it works very nicely and I get a lot of travel, but dirt is an issue. I am thinking about converting to a pull-pull winch - not sure, it's just a thought at this time. But for the high quality of your model, I feel that hydraulics is the way to go.
Set with pictures
BTW, could you tell me what diameter tube you used for your blade?
