hillbilly racing

ok so i have always loved rc car drag racing, but i always thought i could never have enough money to do it but then my buddy showed me a vid on youtube of this guy building a drag car, and i thought and said i can do this, it is way cheaper to build it your self. i know how to build real drag cars so this should be easy for me. but i really dont know how i want to mount my streeing or motor so if some one could post there setup so i can get some ideas it woud really help me out, thanks.
