I use a hot rodded Revo. I use the Revo because of ground clearance and speed. I put in a RB 523 and geared it for top end. I set up a line on my street and run it back and forth. At the end of line, I have two cones for a turn. I move to different positions and keep the line. I want to keep up on aspect ratio, depth perception and peripheral vision. I like using a real R/C car because no simulation in my opinion is real enough.
