CAT Excavator
thingiverse
This is a remix of the original excavator that was from a volvo and it didn't look so good, so i just changed the body, lower body and the cabin so it look more like a Caterpillar. Also i made it to fit a standard size servo for the boom, i used a 12 kg/cm servo from Hobby kin wich is enought I also modelised bushing to fit at the place of the bearings in the tracks, it work well and i didn't want to buy bearings for something i played with like 5 time For track and other boom servo you can buy 4.5 kg/cm servo at 3.50$ each on hobby king.
