Good afternoon everyone. I have a problem I hope you can help me with. As the title says I have a Traxxas Nitro Rustler. It had a 2.5 in it and ran great. Took it out yesterday and it wanted to take off as soon as I started it. I made sure all my batteries were charged and no hang ups in the linkage. Everything looked great. I rebuilt the slipper clutch and put new clutch shoes and spring in it. I thought for sure that would fix it. Took it out, it done the same thing. I had a spare 3.3 so I put it in just to see what would happen. No change. I am stumped. Any and all help would be greatly appreciated.
