Drifting's learning curve puts most first time rc beginners down because these cars have to be setup to drift from weight transfer and balance, chassis setup, suspension, weight distribution, and most importantly just the right amount of power.
Anyone can slap plastic slick drift tires on a touring car and lock both diffs but that gets boring fast. On top of that without a one way up front mimicking a real drift course or gymkhana style course is more of a YouTube phenomenon more than anything.
Drifting will die sooner or later. The appeal just is not there any more. Sort of like rally racing and all kinds of off road racing was huge 80s-90s but that died by 2000. Now look at us 2011-2014 and we have combined rally racing with gymkhana.....whatever happened to the days of Pete Solberg blazing through mud at 60-80 mph with trees on either side of his rally beast?!
