Losi 8 or the Hyper 8.5. I loved the steering of the Hyper car but the Losi has better track prowess. I drive the 8 now and have owned, Xray, Mugens, Hyper 7 and 8 and now the Losi 8.
This car is definitly a driver's car. It is not a dirtbike.
Stick with Futaba servos and pay attention to setup and you will be fine.
