Got the tank running and drive tested it. For some reason the tamiya sprocket on the right side would bind in one spot with one track link and it would ride up over the sprocket. I fussed with it for a couple hours and could not figure out why the bind was happening and decided to change the sprockets. I had been thinking about using the plain sprockets as the m50s had a mixture of plain and fancy chrystler sorockets. After the change the track ran just fine with no issues. My kid test drove it for me.
Also got abunch more detail work done. Its really looking good now. Though i have the lights and brush guards coming up, i loath that part, especially when i make them from scratch...
