You can change top speed, braking and other stuff. Wireless controllers and ya can change lanes.
Gonna give this a whirl and maybe build drag strip later. I have the adjustable transformer and some other stuff already
Saying the 11th for track delivery. Reading up on track material and 1 company uses 1/4 inch pvc. Think I'm gonna use 3/8 or 1/2 inch. Have an in with plastic supplier from seat kits so I can piggyback the pvc on hdpe order. Pvc should weather well and not expand to bad in sun. Goin for outdoor 1/4 mile scale drag strip. All the electronics can be stored indoors.
