Here is a short, independent video (http://www.youtube.com/watch?v=c6ZaWzvCyJU) of the LR2. Again, not a rockcrawler...but it seems to handle things well.

You'll see it perform with one wheel completely in the air...similar to the pics of the Patriot from expeditionwest.com. Also, it goes through a small pit of rocks...nothing big, but it shows the vehicle fighting for traction on split-surfaces.

Can the FDI still move with 2 wheels (say front left and right rear) in the air, or do you need the brake activation of the FDII system to direct power to the other wheels that are on the ground still.

And if so, and I only have FDI - then I will be get stuck sitting on the hill looking like an idiot with my 2 wheels spinnin. The pictures on Expeditionswest, show one Khaki colered one without the badge on the side doing a little hill descent but not climbing.

FDI will send power both to the front and the back at the same time, but power will only be going to one wheel in the front and one in the back. With FDI, the power going to the right or left side goes to the wheel with the least grip, which would cause them to spin if there's not enough traction. With FDII, power is diverted to the wheels with the most grip.
