If you are interested check out this vid, it's a bit boring but it is one of the few vids of a PC1250 set up as a face/front shovel.

The operator did stop....for a second or so...LOL...and then he drove them over (that was the most exciting part in the video...LOL )

The plywood profiles are very handy...and easy to cut on the table...it also helps keep my kids from asking me when they can see something other than a drawing...LOL...

First try using this type of steering control ( this one did not work needed some changes )

Used a Hitec 785 winch servo ( 3.5 turns) and a 12T sprocket ( servo city)
