i just recently traded for a hpi blitz without seeing if it ran first because i trusted the guy. it has the velineon motor and the vxl3s esc on it. it came with a losi mtx pro with spektrum 2.4ghz radio and spektrum sr3000 receiver. when i turn it all on the steering is backwards. left is right and right is left. also when i pull on the throttle or reverse, nothing. the radio has a throttle trim knob on it and when you rotate it all the way to the right the truck takes off until you turn it back or pull on the trigger slows it down as well. i'm lost, hopefully its something simple. any ideas would be greatly appreciated!! thanks
