RC Modders did a series of YouTube videos on his Bruder CAT Telehandler conversion. There are several dealing with just the boom, including the boom extension. This is electric control, not hydraulic.

On my Manitou conversion, https://madmodder.net/index.php/topic,13026.0.html I plan on using a length of 5mm 3D printer leadscrew, but then I'm only trying to animate one section of the boom. Even then it's going to be a tight fit hiding the gearbox inside the boom.

I've figured out a way that with minor modifications to the transmitter, I can use 2 channels to control the speed and direction on up to 5 motors, but only one motor at a time. I plan on using 2 of these set-ups on my Manitou, which will give me the equivalent of 10 channels of control from 4 radio channels. I doubt that I'll ever be coordinated enough to try controlling multiple movements at one time. I don't see not being able to do simultaneous coordinated slew, boom, and cable movements as a problem.
