I have the ESC's programmed, and the "Dig Mixing" works flawlessly with the 6EXA. I have driven it around the basement a bit. I crawled over various objects, cardboard boxes, tool boxes, X-boxes, etc. The dig mixing will definitely take some getting used to, but I am very happy that it works.
I would like some larger tires. I'm looking for something in the 5.5-6" diameter size. Preferably for a 2.2 sized wheel.
