Originally came as brushed it's now upgraded to 4poles brushless. Has great power on road. Has Futaba servo upgrade as well. I just used it for drifting and it smooth and hugs the ground. Those are Hpi wheels tires. And something super cool is the high speed and mediums and low setting on remote in case your teaching someone lower the power. Ok so this is a Thunder Tiger Sparrowhawk DX now its brushless. one of them. This is Taiwan biggest and best RC brand. 1979 it's been around for many years. They really are into nitro stuff. This is a great car good stance from nice shocks. Battery's not included.
