Got a few more things done yesterday. I got the hole drilled for the head motor and adjusted its tension spring so it's tighter, finished the center foot's caster wheel, added a quick disconnect for the battery so I don't have to keep using a wrench and screwdriver to remove the wiring, and I ordered the wheels for the foot drive. Sadly the wheel for the head motor hasn't arrived yet.
About the foot drive wheels. The source for better wheels I was given was out of stock. So after searching and searching the Internet I eventually checked ebay. There I found the original Razor E100 belt driven rear wheels I was told can't be found. And for only about $17.00. Just one thing. They're in China. I bought two of these wheels but because of them coming from China, I don't know if they'll make it here on time for the Droid-Con. I tried working with those "other" wheels I have but there's just no way. So here's hoping they get here with time to spare.
