My tail motor starts as soon as battery is plugged in and the blades are going backwards. I am new to this any help would be appreciated.

If the tail motor runs at full speed all the time no matter where the throttle is, then it is most likely a blown tail motor fet on the board.
Usually the rotor will turn backwards when you plug in the tail motor wire to the board backwards.
Good luck

You have certainly blown the tail fet on the board, get it replaced by an experienced member on this forum. Here is some good reading:http://helifreak.com/showthread.php?t=341594

Sounds like short-circuited fet´s protection diode (bad fet). If you have soldering skills for SMDs or you want to contact someone to do the job for you look here:
