I have a 1/24 digital race track with all the new electronics. New control unit, drivers displays, tower etc. If I want to run more than the 4 cars in 1/24th I guess I would have to go to 1/32 and run 6 cars. Can you run 6 1/24th cars? How do you get wireless controllers to run 6 cars? I have 4 wireless controllers and two wired controllers that I don't use. Can I use these wired ones with the wireless controllers and where would you connect controllers for 5 and 6. Thanks Ron
