[Biff]

Ball casters at the front. Double kit wheels in the center, (chain in between) single kit wheels at the back. Tank drive. Stock kit transmissions, stock at this point ratios, 4 cims, 9 fps. Water cut sprockets and spacers all around, Machined "hats" to hold the driving sprockets on the transmissions. Shipped and bringing sprockets that if installed will either lower speed to 7fps or raise it to about 11fps. One time change and then off the the scale. We may have to loose a pair of Cims if we can't make weight. Plans at this point to add belting to the center stock wheels. Drove nicely with out the complete arm on, but too much wheel spinning. Turns centered at the place I expected it to.
