Lou , I was going to go with 1 24V dewalt 2 speed drill motor with steering brakes and clutches BUT for the modeling and an electric motor , seems to be nonefficant . so It will be 2 milwaukee 2 speed drill motors . For some reason cat has 2 electric drive motors in the new D7E
This will be close to the size of joe's D9R
Henry , It's getting time to get someone to run all those parts for me . It ties me up I can't get to other things .
