hows it goin all

1) aluminum parts....if these are so bad (cause when you crash and break a part, an a-arm lets say, then it'll bend) so why not just bend it back and you're good to go?

B) crystals.....i got a pair of (green) crystals from my old traxxas electric rustler, and i tryed puttin them in my evader (and controller) and it doesnt work, anybody know what gives? I mean crystals are crystals, they should work on any receiver/controller.
