About a year ago...I remember seeing a note when I was first trying to figure out what to get so that I could make my SC104x4 legal after the SC104x4 was announced, but before they were available...and then I found out RCPS runs 4x4 as an open class and bought everything that I wanted to buy in the first place. (Drift assist gyro included....but not used for racing...just practice so that I could see how the truck SHOULD slide around the corners....)
