I'm assuming you're asking about the electronics? It has a Hobbywing Quicrun16BL30 ESC with an old Trinity Cobalt B brushless motor from the era of the original Mini T. And standard Spektrum SX107 servo. Though I JUST installed the new Spektrum SX117 servo. As for components, it has the MIP Ball Diff, Aluminum Top Shaft, and Slipper set, and CVD's. And a Steel weight plates set.
