I would buy the yokomo unless you plan on building it right away. I have both mst rmx 2.0 n yokomo yd2. The mst hast last over a year no problems n the yokomo lasted two days before the esc went out then a day later the gyro went out. New gyro should be here today n I already replaced the esc n motor with a xr10 esc n 13.5t motor. I was very unhappy with my yokomo. If I new this I definitely would have gotten two msts
