Fastest stock RC car I believe. No batteries but requires 2 x 2s 5000 to 10000maH for normal mode, 2 x 3s 5000 to 8400 maH for High Speed mode. Includes transmitter, With add-ons can provide telemetry to Smart phone. Only been driven a couple of times. I bought it because it was such a cool looking car. Would keep it just for show but need the cash.
