The wheels and tires are from 2 8" John Deere monster tread combines. The wheel covers off the rolling thunder fit right into the new wheels so I just glued them in place to give them an original look. The winches are 1:10 scale off road rc winches from 3racing. They are fully functional. I have made a detachable control box and 7.2 volt battery pack to control them. I hope to have pictures up this week, I have been extremely busy lately.
