Electrics, specifically brushless motors and lithium-polymer batteries, have improved by enormous strides in the past few years, not to mention the 80's. Thats probably one of the biggest changes in the hobby, and well worth looking in to. There are also things that are so new that have only been released in the past year or two. (2.4 Ghz radios comes to mind) Other than that, RCU has all the information on anything you may want to know, so check out the "search" button, or simply ask. There's no shortage of people who want to help! [sm=shades_smile.gif]
