I'm looking at upgrading to the VXL system. I know a bunch of people have commented that the VXL motor is great, but perhaps getting a different ESC might be better. I came across this today and was wondering what peoples opinion is on it: http://www.hobbypeople.net/gallery/701487.asp. It a Castle Sidewinder 1/10 ESC & 5700 Motor Combo. It looks like a good deal, but I'm not sure about the KV. Thanks in advance.
