High reach excavator?

[cyanide]

Hi guys, just a general question here.

I was watching and filming a Link-Belt 700LX High Reach doing a bit of demolition work the other day
(see video here) and I was wondering if anyone has made one in the RC world?

I am hoping to build a foresty excavator at some stage, the boom set up is a little different to the dirt diggers, but nothing like the high reach demolition booms.

Anyway, just curious more than anything.
