You know the tehter cars from the 50's? I am makeing a pullback car I got from the doolar store into one. It will be powered by a high speed motor and maybe a 4 to 6 cell pack. It will have speed adjustment on the top to adjust speed to your ability. It will also hopefully hit 30 mph+. It would be crazy if it hit like 70mph+. I will add cardboard wings on the front for extra downforce to hold it on the ground. I hope you will try it to! BTW It will still be crazy if it hits 10 mph+! Do you like my new avatar?
