I just bought a 2nd hand one last month with a very reasonable price.
I have no blame on this baby for regular off road running, climbing up little stair case, running over the mud and sandy land.
the previous owner installed mc300 with two 540 motor. But i highly recommand a more durable and powerful esc and servo.
P.S. As I know some of the parts are compatible with other tamiya chassis, if any brother have any idea towards any parts of this baby. Please share!!!
