John,
The batteries actually fit pretty easily. In the last couple videos I have been using a two 850 two cell lipo packs. They fit side by side under the hood, and I plug them in and bunch up the wires and slide the hood onto the chassis. They seem to last really great! I have not done a real good check, but I know they would make 30 minutes for sure! The little motors and standard servo of the blade don't task the two batteries too much. I do notice that the battery running the servo is always a bit lower voltage than the other.
I need to adjust the right side drive train, so I'll try to get some more video of some of the different detail.
As for the winch, when did you see a winch? Did I take a winch off of it?
the little 1:50 AC did have a ripper on it, but don't be confused by me switching dozers and scales mid conversion.
