Re: RC Cars/Trucks
The biggest changes since you were in it (I also was in it 15 years ago and got out of it but have recently returned to RC, in fact I flew my plane today) are in the radio and electric technology. The invention of the brushless motor and ESC has revolutionized RC cars. Traxxas offers an RC buggy like the RC-10 or Losi JRX-pro SE (my last Losi buggy) that is stock out of the box 70mph on the radar gun. Like I said....technology has grown by leaps and bounds.
They now have these new 2.4ghz radios with bind and drive technology where gone are the days where you had to worry about someone else on your frequency. Once you bind a vehicle (or plane) to a radio, it's bound for good and will ONLY respond to your radio. So no need to worry about it! And the antennas are only a few inches long, not 3-4 feet like the old 72-75mhz technology.
I would definitely not agree with TA dominating the RC car market. Traxxas, IMHO, dominates. They offer so much variety with really good quality cars. The only reason that some might say TA has pulled ahead of Losi is that Losi is no longer carried by the biggest RC supplier, Tower Hobbies. But they are still definitely in the running.
