Hi
A word of advise to new and future new Arrma owners, if you are going to buy a Arrma RC you need to be prepared to replace all of the electronics. I would test the electronics to make sure it all works and then I would put it aside to use as a backup system. Do some research and get the best electronics that you can afford. If you got one of the Brushed Arrma RC's and you don't want to upgrade to BL I would recommend getting a older Tekin or Novak ESC, these can take a hell of a beating. One that I would recommend is the Tekin Rebel 2 ESC, you can find them on eBay ever so often, and it's worth every cent you pay for it.
Here are the specs for the Tekin Rebel 2 ESC if you are interested.
