I have already replaced the servo. He has taken jumps but it has happened when he is at wide open throttle on a bumpy turn but the last time the wheele locked up ont he chassis, broke wheel and bent axle. Do these not turn very well? Are the tires too big for this truck so thats why they get jammed up? Why does the Monsoon not do this? I am very happy with its performance but the steering is really bad.
