Hi, Welcome to an interesting and sometimes frustrating hobby that will soon get rid of your pension,
If you want to start with a RTR I suggest you go to probably one of the most trusted dealers in the USA and that is ---
Home - IMEX Model
This is a Taigen Dealer based in Florida and the RC Tanks section of IMEX is in the very capable hands of ERIK he is as straight as an arrow and you can e-mail him any time with any questions,
Shaun.
