i'm looking into getting a 1/8 buggy roller, and i have no idea where to start once i get the roller. i dont know what kind of servos to get or what engine or reciever or transmitter, i dont know anything, i'm not totally new to rc, but i have always bought everything rtr, this would be the first time that i would have to buy and build my own car, so if you have any suggestions on some moderately priced stuff to stick in a roller let me know, i really need the help
