Get a tekin rs pro and gen2 6.5 and be done.
As mentioned, lrp and add to Orion are a good esc for this car.

It's a feather weight and a 6.5t is holy Jesus fast. 5.5 at the most but you will be hitting velocities on the street that if you hit anything immovable the buggy will self destruct into pieces.

Lrp and take your pick of mod 540 motor or tekin setup and your good.
