Recently got my dunerunner up and running and I was driving it n some lite mud after few days of rain and it ran good took it out again next couple days and about half hour into playing wih it I squeeze the trigger to gas it and it goes then the wheels lock up immediately or if I has it then let go of the trigger fast it locks rite up like the brakes are engaged any advice appreciated

Check your throttle/brake linkage, as well as the brakes themselves.

There are 2 set screws on the bearing mount for the center drive pinion that can act up.

Does it roll easily, or does it bind with the engine off also?
