I bought this truck years ago brand new to race it at our local track, and never actually got to race it. Shortly after the 22SCT 2.0 version came out and I did some of those upgrades (I cannot remember exactly what I replaced and what I did not). Upgrade to a Trinity D3.5 (13.5T) brushless motor, and have the original Dynamite platinum 17.5T brushless motor included as well.
