Nice!!!
I know how difficult building an Backhoe Loader can be.
I made ONE before, and it is still in building process, due to extremely complexity on such a small place.
Very nice job with the functions, and the remote... especially the sliding backhoe, lifting arm up is somehow slow, thats way I used LAs.
As I see, you used 8466 drive steer combo for the axles, thus you got very limited turning radii, I mean steering angle, but I like AWD and AWS!
Overall very nice and very functional model!
