Thats good, it will help you to enjoy the car for years to come. Not that you cant enjoy it if you buy a RTR, but now YOU will know the car in and out. I got my first RC when I was 9 or 10. It was a used Tamiya monster truck in pieces in a box. It took me weeks to build it buying what I needed little by little, but it was so worth it. Hope you have tons of fun and buy more cars in the future!
