Cat 340D Excavator build

[crueby]

Got enough wired up to do some testing - the bucket and stick motors working well, the motor that drives the two cylinders on the main boom does need an upgrade though - with the weight of the booms and bucket extended out, it is really struggling. So, I need to either add some more gear reduction or swap out to a different motor with some more oomph. Still need to wire up the cab rotation motor and test that one...
