My other major hobby right now is R/C or radio controlled vehicles. And I'm not talking Wal-Mart or Radioshack toys. I'm talking about real R/C cars, expensive, fast, and fun, both electric and fuel cars. One of my vehicles, a highly modified Traxxas Rustler, is tons of fun to play around with. I have invested hundreds of dollars into it. I would say it goes at least 30mph, but I haven't had the chance to GPS it for speed. My other vehicle is a two-stroke engine-powered on-road car called the Ofna LD3, which hits around 55mph (I have an aftermarket engine). I compete with it at the local racetrack. Here is my R/C gallery (which needs an update BTW).
Anybody else into these things? They are really fun but will eat through your wallet. Ask me questions if you like or post them in this forum.
