Need your help guys.

I finished assembling my yokomo YD-2 Plus this week. I have the racing performer brushless speed controller and Futaba T4PLS. 

The frustrating thing now is the car does not go reverse, and not sure what I have done  wrong so that the does not go reverse. 

Also the ESC keeps blinking green. 

I really need to help guys and hoping to get some insight in order to sort out this issue.
