Cat 777D Mining Truck

[modelman]

Lilgiantsjoe-the tires are actually 3-1/2" dia.x1-5/8" i.d. I could not find any this size so I thought I would see if I could make them. I am thinking about dual g.m.'s in the wheels but not sure if it will turn. I have no experience with mixing in the radios but thought that may have to be used for turning. May need some help on this when I get there. tc1cat-I am just starting and not sure about anything yet. I am not to good at engineering and design I just start building and go from there and sometimes that gets me in trouble but I hope it will all work out. I may ask for help as I go.
